Description

Diamonid disk

Technical field

The present invention relates in upward installations such as disc grinder as whirligig (throw), carry out that concrete, stone material etc. are various to be ground the grinding of object (in the scope of this specification and claims, except specific occasions, " grinding " speech uses comprising on the meaning widely of " cut-out ") Diamonid disk of work.

Background technology

Had on the disc face in various fronts at the discoideus matrix that steel plate etc. is made with proper spacing, utilize soldering, laser weld or bonding agent (binder) etc., except the Diamonid disk of the fixing a plurality of diamond particles in the position central portion reaches the degree (Japan Patent discloses flat 6-210571 communique, the Japan Patent spy opens the 2000-167774 communique) of practicability.

The installing hole that this Diamonid disk forms by the described central portion at matrix is installed on the rotating shaft of shape device such as disk type grinder, speed with regulation makes its rotation, faces concrete component, stone material, brick and tile and be covered in coating on its upper surface etc. with described disc to be ground (grinding) object and to carry out the grinding operation.And this Diamonid disk changes size (diameter), the form of disc according to the purpose of using or is fixed in the granularity and the configuration density of the diamond particles on the disc face.

But there is technical problem as described below in existing Diamonid disk.

At first, the diamond particles that fineness ratio is bigger on the same rotational trajectory with less configuration distance and generally under the fixing unevenly situation of density, in actual grinding work, form the state after the diamond particles that the diamond particles that is positioned at the back on the common rotational trajectory is hidden in the place ahead.Under these circumstances, the diamond particles that is disposed at the rear can not be made effective contribution to grinding, causes overall grinding efficiency low.Such tendency is remarkable especially in the grinding operation that with overburden operation of for example elastic coating film etc. is the bigger adhesive material of having of representative.

Again, under the situation of aforesaid structure, if long-time the use then taken place and the loss inequality corresponding to the contribution of grinding operation in the diamond particles on the disc face.Consequently, grinding efficiency thereafter reduces, and the life-span of Diamonid disk is reduced.

Again, if with the diamond particles random arrangement on the disc face, it is inhomogeneous that it is not had on the whole, then when carrying out the grinding operation from central division the side direction periphery grinding chip of discharging can be subjected to the influence of diamond particles, stop up easily, this is bad to the grinding efficiency influence.

Second, in above-mentioned Diamonid disk, the diamond particles one by one that will be fixed on the disc face is configured to make each diamond particles can have independently rotational trajectory respectively respectively, consider further to improve grinding capacity, if but increase the number of diamond particles like this, configuration as mentioned above, then the configuration of each diamond particles in process of production and fixed operation are numerous and diverse, and production efficiency significantly descends.

The 3rd, central portion and particle nearby thereof wear away not so much in the grinding operation in each diamond particles on the disc face, discarded at last but in case the particle of disc face periphery configuration is subjected to wearing away disc, it seems it is unfavorable from the viewpoint of resources effective utilization.

The 4th, under the situation of existing above-mentioned Diamonid disk, just the grinding special use on the meaning of carrying out narrow sense such as chamfering with the disc face can not be used in other purposes.

The present invention makes in view of such situation, the 1st purpose of the present invention is, provide just to replace without any change with the commercially available prod and use, and all diamond particles can both be to the grinding operation effectively, make contributions with having equal opportunities, it is uneven that long-time use also is not easy to take place each diamond particles abrasion, easy from the outwards peripheral chip of discharging of the central portion of disc, the Diamonid disk that grinding is used.

The 2nd purpose of the present invention is that the grinding Diamonid disk that can irrespectively simply set the position of diamond particles on the disc face with number that is fixed in the diamond particles on the disc face and position form thereof is provided.

The 3rd purpose of the present invention is, the existence that is conceived on the disc face in the fixing diamond particles the low diamond particles of the percentage contribution of grinding operation is provided, utilize this part diamond particles, discern the manufacturer of this Diamonid disk etc. easily from outward appearance, brand-new and grinding Diamonid disk that appearance design is excellent.

Also have, the 4th purpose of the present invention be, provides out of trade except doing with the grinding of the narrow sense of disc face, can also be used in the grinding Diamonid disk of purposes in addition.

Summary of the invention

In order to realize the 1st purpose of the present invention, the 1st kind of form of the present invention provides the grinding disc, fixes a plurality of diamond particles on the grinding function face of disc, it is characterized in that,

To be on the common rotational trajectory, the spacing distance between the diamond particles before and after having on the direction of rotation is set at than big with the spacing distance of the diamond particles that is in the vicinity on the adjacent rotational trajectory that directly makes progress.

Adopt such structure, spacing distance between the diamond particles before and after having on the common rotational trajectory, be set at than big with the spacing distance of the diamond particles that is in the vicinity on the adjacent rotational trajectory, therefore concrete or stone material etc. is being carried out in the operation of grinding, when Diamonid disk rotates, be between the diamond particles of front and back of common rotational trajectory and can guarantee sufficient interval.Consequently, the diamond particles that the diamond particles that the back can not take place is gone ahead of the rest on direction of rotation covers and causes wearing away uneven situation, and each diamond particles can both be made contributions to the grinding operation effectively.Again, between diamond particles adjacent on the direction of rotation, the gap can be formed effectively, therefore the grinding chip can be repelled smoothly.This also can improve grinding efficiency.

Because each diamond particles can roughly wear away equably, therefore can bring into play grinding performance long-term and stably, thereby can prolong the life-span of Diamonid disk again.

Again, in above-mentioned Diamonid disk, adopt the structure that above-mentioned a plurality of diamond particles is configured to the row shape, the structure that formation can more smooth repulsion chip makes the Diamonid disk of production efficiency excellence.

Again, use in the Diamonid disk in described grinding, the row shape of described a plurality of diamond particles configurations is, can make to be on the described adjacent rotational trajectory, and, form continuously to periphery from the central portion outer rim in the gap that forms between each diamond particles of contiguous front and back mutually on the direction of rotation, the inner diameter end in the gap that this is continuous is gone ahead of the rest on direction of rotation, the external diameter end is back row ground on direction of rotation, forms the row shape in the gap that tilts diametrically

So form and to utilize the structure of the rotation of disc from the more smooth discharge grinding in the gap chip between each diamond particles.

Again,, form the inner diameter end in described continuous gap and external diameter end, so can realize utilizing the structure of the described grinding chip of the more smooth discharge of rotation of disc at the vortex shape of skew more than 20 ° on the direction of rotation at described grinding Diamonid disk.

In order to realize above-mentioned the 2nd purpose, the grinding Diamonid disk of the 2nd kind of form of the present invention, on the grinding function position of disc, fix a plurality of diamond particles, it is characterized in that, the fixed position pattern of adjacent a plurality of diamond particles is turned to the configuration of regulation, be formed on the diamond particles group unit of grinding function position configuration usefulness, this diamond particles group unit in the configuration of a plurality of grinding functions position row shape, is fixed on each diamond particles on the grinding function position with this.

Adopt such structure, in grinding function portions such as disc faces, as a unit, the mutual configuration relation of only considering each diamond particles group unit is configured and gets final product with the diamond particles group unit of one or more medellings.Therefore can be rapidly and easily on the grinding function position of disc face etc., set the position of diamond particles or be fixed.

Its reason is, the a plurality of diamond particles that belong to identical diamond particles group unit are mutually near expansion on the whole, when concrete or stone material are carried out the grinding operation, these diamond particles are in aggregates to carry out grinding, so can regard a diamond particles group unit as a big diamond particles on apparent in fact.

And on performance, can bring into play not second to being the grinding performance of object existing disc of desired location on the grinding function position of disc etc. with diamond particles one by one.Here, the medelling of the configuration of described regulation is not limited to a kind of pattern, also can be various modes.

Again, in above-mentioned Diamonid disk, consider the grinding workload (grinding burden) that diamond particles bears, the direction of the affiliated diamond particles group unit of this diamond particles is differently disposed, so the difference of this direction has changed the rotational trajectory of each diamond particles of the diamond particles group unit that belongs to identical.In other words, by changing above-mentioned direction, can change the width of the rotational trajectory of diamond particles group unit.Therefore can adjust the grinding burden of each diamond particles.Again, the position deviation on radial direction mutually in diamond particles group unit, under the situation that the part of rotational trajectory overlaps, reverse alternately by the direction that makes this overlapped diamond particles group unit, the inhomogeneous of grinding can be eliminated, the weight difference of the grinding workload of each different diamond particles of allocation position can be eliminated.Consequently, each diamond particles is worked effectively, improve grinding efficiency on the whole.

Again, at above-mentioned Diamonid disk, grinding function portion is planar, to external diameter end one side each diamond particles group unit is configured to continuous vortex shape from inner diameter end one side of this face, so from practical face in fact, can realize face (for example disc face) configuration of the diamond particles group unit of balance generally simply for the grinding function position.Can access again and meet practical purpose and Diamonid disk easy to use.Here, described vortex shape can be a vortex, also can be two or more vortex.

Again, at above-mentioned Diamonid disk, the grinding function position is planar, along with the external diameter end side to this face is close, make the interval configuration straitly gradually between the diamond particles group unit, so, from practical face (grinding function face), to obtain the balance of the configuration of diamond particles group unit on the whole as for example above-mentioned disc face at grinding function position.Just usually at the grinding function position of disc etc., close along with to peripheral part, speed on circumference is also fast, diamond particles group unit in this place's configuration is big more to the percentage contribution of grinding, the grinding burden of diamond particles is also big more, and constitute as mentioned above, then can be suitably corresponding therewith, can carry out grinding with high efficiency.And owing to be outer part, the grinding chip is also discharged than being easier to.

Again, in above-mentioned Diamonid disk, described diamond particles group unit constitutes to be configured to 3 leg-of-mutton diamond particles, so, diamond particles group unit has directionality, thereby only a pattern also can change various direction configurations, can realize that reality goes up more satisfactory structure.

In order to realize above-mentioned the 3rd purpose, the grinding Diamonid disk of the 3rd kind of form of the present invention except the central portion of disc face, to periphery, is fixed a plurality of diamond particles from this central portion outer rim footpath one side, it is characterized in that,

Fixed diamond particle at least a portion of disc face utilizes a plurality of diamond particles to form the literal or the figure of point-like.

Adopt the Diamonid disk that constitutes like this, purposes, performance or the producer's title etc. that show this Diamonid disk by the point-like literal described or figure during work on showy disc face can design processing attractive in appearance simultaneously, the value of raising commodity.Can bring into play in fact roughly identical grinding function generally by considering the configuration position of literal etc. again with existing Diamonid disk.

Again, at above-mentioned Diamonid disk, the disc face of fixed diamond particle is roughly divided into by the part of central part and other parts, in described part by central part, the configuration diamond particles, make described diamond particles form the literal or the figure of point-like, so, the low part of grinding function on the position by central part, the zone of point-like literal or figure ground fixed diamond particle is described in formation, produce the effect in the appearance design, other parts that grinding function is high on the position are mainly made contributions to grinding work.Make it produce the grinding performance identical in fact thereby can access, have in recognition function and the design simultaneously, the Diamonid disk of the effect in the propaganda with existing Diamonid disk.

In order to realize above-mentioned the 4th purpose, the grinding Diamonid disk of the 4th kind of form of the present invention, to installing hole from its central portion of rear side depression to whirligig one side is being set with the degree of depth of regulation, one side's disc face is fixed a plurality of diamond particles from this depressed part to external diameter, it is characterized in that

Outer peripheral portion fixed diamond particle also from the outer peripheral portion of disc face to the disc back side.

Adopt the Diamonid disk of such structure, in grinding work, can bring into play the grinding performance identical with existing Diamonid disk to concrete and stone material.And outer peripheral portion that can enough discs is ground object to concrete or stone material etc. and carries out the cut-out on the narrow sense (meaning) or form groove thereon.

Outer peripheral portion at the described disc back side is arranged on rear side spherical with circular projection, adopts such structure, so can access the well behaved Diamonid disk of sense stricto cut-out.

Again, in above-mentioned Diamonid disk, the outer peripheral portion of formation from the outer peripheral portion of described disc face to the described back side, the configuration density of fixing diamond particles impartial structure on whole circumference is so can access the well behaved Diamonid disk of sense stricto cut-out.

In order to realize above-mentioned the 4th purpose, the grinding Diamonid disk of the 5th kind of form of the present invention has installing hole at the central portion of disc face, and front shape is rounded, it is characterized in that,

And each diamond particles 2 is configured to the row shape.Under the situation of present embodiment, the above-mentioned row of each diamond particles 2 be it seems from the part, each nearest 1 diamond particles 2 (2b, 2c) of adjacent diamond particles 2 (2a, 2a) and each rotational trajectory of its two neighbour before and after on each rotational trajectory is seen from the front to be arranged as rhombus.And on the whole, keep at a distance and form continuously in the many places that are arranged in of above-mentioned rhombus.Again, on each adjacent rotational trajectory, also close mutually in direction of rotation, as to form between the diamond particles 2,2 (2a, 2b or 2a, 2c) before and after each a plurality of gaps 76 form vortex shapes from the above-mentioned outer rim 5 of disc 1A inboard a little continuously to above-mentioned disc neighboring.This continuous gap 7 is as formed on the position between the dotted line adjacent among Fig. 3 (imaginary datum line), its internal diameter end 7a goes ahead of the rest on direction of rotation, row behind the external diameter end 7b, and on the front, see, circular-arc inclination formed from internal diameter end 7a to external diameter end 7b.The part of the internal diameter end in above-mentioned continuous gap 7 and the part of external diameter end are offset predetermined angular α and form vortex shape (with reference to Fig. 3: angle [alpha] is approximately 20 degree in this embodiment) and arrange on direction of rotation.But the afore mentioned rules angle [alpha] also can be more than 20 degree.

The grinding of the present invention of Gou Chenging can utilize the installing hole 3 of the central portion setting of Diamonid disk to be installed on the rotating shaft of commercially available disk sander (not shown) etc. with Diamonid disk like this, concrete or stone material etc. is being carried out in the work of grinding, each diamond particles is made effective contribution to grinding work, can improve grinding efficiency.

Again, continuous a plurality of gaps 7 of Xing Chenging form to above-mentioned disc neighboring 6 continuously from the inner a little place of the above-mentioned outer rim 5 of disc face 1A as mentioned above, therefore disc face 1A goes up the grinding chip that produces and can be discharged to the disc neighboring smoothly from these gaps 7, can not stop up.Thereby the grinding performance that can play stably can improve grinding efficiency.

Embodiment 2

With reference to the accompanying drawings 1 embodiment of the present invention's the 2nd form is described below.

Shown in Fig. 4,5, be formed on disc face (grinding function face or the grinding function position) 1A on 1 face of the disk shape matrix 1 that steel plate makes limited range fixed diamond particle 2.

The disc central portion of above-mentioned disc face 1A forms it is installed on the installing hole of using on the disk sander (not shown) 3.The central portion that has this installing hole 3 in central authorities is made tabular (flat condition), and, whole central portion is caved in to rear side (downside among Fig. 5) with the degree of depth of regulation, form depressed part 4.The periphery of this depressed part 4 (outer peripheral portion), face side form the circular-arc shape that bloats, and the place that forms described outer rim 5 is to the disc face 1A of disc neighboring 6, make its have curvature that outer rim one side in the past slowly increases overleaf side form the form of flexure plane.Diamond particles 2 utilizes said method to fix at the disc face 1A from the inboard a little position of above-mentioned outer rim 5 to the zone of disc neighboring 6.

Among the embodiment of the 2nd form of the present invention, diamond particles 2 fixing on disc face 1A, be by with the form formation pattern of a plurality of diamond particles 2, form 1 unit A of diamond particles group, the configuration of many formation of the unit A of this diamond particles group row shapes is carried out with regulation.In this embodiment, forming above-mentioned medelling carries out with 1 pattern.

The unit A of diamond particles group of present embodiment forms 1 unit A of diamond particles group with 3 adjacent diamond particles 2 with the pattern form that is disposed at each summit of triangle respectively.

Under the situation of this embodiment, the configuration of each diamond particles group unit on disc face 1A, shown in imaginary datum line 17 among Fig. 4, on with the rightabout of the direction of rotation (direction shown in the arrow R of Fig. 4) of Diamonid disk along forming 17 configurations of 1 Vorticose datum line to outside diameter from internal side diameter, again, along with close to disc neighboring 6, interval between the unit A of diamond particles group (interval of adjacent front and back on the Vorticose baseline) becomes narrow gradually, near neighboring 6, the density of diamond particles 2 is higher.

Again, be configured to the Vorticose diamond particles unit A of group, in order to eliminate the inhomogeneous of grinding, each a part of diamond particles of the unit A of diamond particles group that is configured to these Vorticose front and back is overlapping on rotational trajectory top on radial direction, be configured to the unit A of diamond particles group of these Vorticose front and back, the direction that is configured to the unit A of this diamond particles group on the radial direction is reverse mutually.But the direction of the unit A of diamond particles group is not limited to reverse, also can be in the same way, and perhaps the direction of the unit A of diamond particles group with the angle deviating of regulation, for example departs from 30 ° of configurations in regular turn one by one.

The grinding Diamonid disk of the present invention of Gou Chenging like this, when grinding because a plurality of diamond particles that will effectively dispose form medellings, constitute diamond particles group unit and be disposed on the disc face 1A, so can simply and promptly each diamond particles be located on disc face 1A.Therefore, even fixing diamond particles number increases on the disc face, also can irrespectively obtain Diamonid disk simply with this increase.

Embodiment 3

With reference to the accompanying drawings 1 embodiment of the present invention's the 3rd form is described below.

Among Fig. 6, Fig. 7, diamond particles 2 limited ranges are fixed on disc face (grinding function position) 1A that forms on 1 face of discoid matrix 1 of steel plate manufacturing.

On the disc central portion of the disc face 1A of present embodiment, be formed on commercially available disk sander (not shown) and go up the installing hole 3 that usefulness is installed.Central authorities have the central portion of this installing hole 3 and make tabular (flat condition), and, whole central portion is caved in to rear side (downside among Fig. 7) with the degree of depth of regulation, form depressed part 4.The periphery of this depressed part 4 (neighboring) forms the shape that bloats to the face side circle, make from as the place of above-mentioned outer rim 5 to the zone of disc neighboring 6 with the curvature that increases gradually to outer edge side to the curved one-tenth flexure plane of back side lateral bending.

In the Diamonid disk of present embodiment, the regional rough idea of the fixed diamond particle 2 of disc face 1A is divided into by the part 1a of periphery with by the part 1b of central part, the part 1b that connects the outer rim 5 of depressed part 4 by central part, form and see from the side and be roughly tabular surface (face of correctly saying so and constituting) with larger radius of curvature, arrive the described part 1a of disc neighboring 6 thus, form along with the arc surface structure that progressively retreats to outer circumferential side toward rear side (downside among Fig. 7) by periphery.And the face that links to each other with arc surface with the face with above-mentioned general planar constitutes.

By on the part 1a of periphery, pay the utmost attention to grinding function configuration diamond particles 2 as described below above-mentioned.That is to say, each diamond particles 2 is that the fixed position of adjacent a plurality of diamond particles 2 is formed pattern (immobilization) with the form of regulation in the configuration by the part 1a of periphery, form the diamond particles unit A of group, the unit A of this diamond particles group is configured to row shape (vortex shape) on a plurality of disc face 1A.

The unit A of diamond particles group of this embodiment forms 1 unit A of diamond particles group with the pattern form that 3 adjacent diamond particles 2 is disposed at leg-of-mutton each summit.

So, implement with the fixing method such as temporary fixed diamond particles 2 of for example can utilizing on the adhesion sheet that above-mentioned pattern form is carried out.

Again, the above-mentioned diamond particles unit A of group is 1 the vortex shape baseline configuration that forms to outside diameter from internal side diameter on the rightabout in the direction of rotation (direction of the arrow R of Fig. 6) of Diamonid disk in the configuration by the part 1a of periphery, the interval that makes the unit A of diamond particles group during configuration along with to disc neighboring 6 near progressively narrowing down, near the density that makes diamond particles 2 disc neighboring 6 is high density.

Again, it is inhomogeneous in order to eliminate grinding to be configured to the Vorticose diamond particles unit A of group, each a part of diamond particles that is configured so that to be configured to the unit A of diamond particles group of these Vorticose front and back overlaps on rotational trajectory top, again, be configured to the unit A of diamond particles group of these Vorticose front and back, the direction that is configured to the diamond particles group unit on the radial direction is reverse mutually.

On the other hand, the diamond particles 2 that is fixed in by the part 1b of central part carries out the setting of position according to the viewpoint of considering outward appearance.This near the part 1b of central part except the part (being part in this embodiment) of footpath direction by central portion, utilize a plurality of diamond particles 2 to be configured to form the literal 27 (or figure) of point-like in the front, do not form the part (the part in the present embodiment) of point-like literal 27 at this, with the vortex shape form configuration diamond particles group unit A identical with the part 1a that leans on periphery by central part.

Take such structure, utilize the diamond particles 2 that is fixed near peripheral part 1a, on performance, can bring into play the grinding performance of the excellence identical with existing Diamonid disk.

Again, the part 1b by central part makes the part that forms point-like literal 27 in a circumferential direction join together harmoniously with the part maintenance at the partial function configuration diamond particles unit A of group that depends on periphery 1a.These diamond particles 2 itself use and the part 1a of close periphery and the identical diamond particles of part 1b of close central part, but, in the diamond particles sum, be fixed near the number of the part 1b of central part number and lack than the part 1a that is fixed in close periphery.Therefore the part 1b of close central part, only works in complementary grinding being the little position of working in common grinding work on the place.

On the other hand, in appearance, near the density of the part 1b of central part, lower than the density at the unit A of diamond particles group of the described densification that can see by the part 1a of periphery, it is wider to distribute.Therefore, the point-like literal 27 (or figure) of formation is more showy.

The grinding Diamonid disk of the present invention of Gou Chenging not only is used in the grinding industry like this, and owing to form point-like literal or figure, producer's name and model are seen easily, therefore, also are desirable for the user.Again, form the part of above-mentioned literal or figure, owing to being part in the inner footpath that is not easy to wear away along with effluxion, thus see these literal or figure easily, even these literal or figure can not wear away yet when Diamonid disk itself goes out of use.Again, form the part of above-mentioned literal or figure, its diamond particles is few, can reduce the waste of resource.

And fixing in the above-mentioned pattern form for example can utilize on thin slice method such as temporary transient fixed diamond particle 2 to implement.

The unit A of this diamond particles group in the configuration of the part 1a that leans on periphery is, the interval near the disc neighboring 6 unit A of diamond particles group progressively narrows down, near disc neighboring 6, the density of diamond particles 2 is than higher, simultaneously, dispose equably in the whole circumference upper density.

Again, on the rightabout of the direction of rotation (direction shown in the arrow R of Fig. 8) of Diamonid disk from interior all sides to the outer circumferential side vortex shape unit A of diamond particles group of configuration, in order to eliminate the inhomogeneous of grinding, each a part of diamond particles of the unit A of diamond particles group of the front and back of this vortex shape configuration is configured on rotational trajectory top overlapping, and the unit A of diamond particles group of the front and back of this vortex shape configuration to be configured to the direction of the diamond particles group unit on the radial direction reverse mutually.

And from the peripheral part of above-mentioned part 1a 8 one sides to the back side by periphery, also being described diamond particles disposes continuously with the form of the unit A of diamond particles group.

On the other hand, be fixed in diamond particles 2, from considering outward appearance, the decision allocation position near the part 1b of central part.At this part 1b near central part, except a part (leaning on the part of central part in the present embodiment) radially, utilize a plurality of diamond particles 2 to form point-like literal 27 from the front is fixed diamond particles 2 (or figure), in the part that does not form point-like literal 27 (part at close center in the present embodiment), with the form configuration diamond particles group unit A identical with the part 1a that leans on periphery.

Like this, by fixed diamond particle on from the disc neighboring 6 of dull and stereotyped ring-type to the part of the peripheral part of the back side 8 one sides, the peripheral part performance of disc neighboring 6 and the back side 8 one sides has a kind of function of rotating knife of the thickness of regulation.Therefore,, make this disc face 1A, carry out the cutting on the narrow sense meaning, then can cut simply and form the such work of slot stick and the cut-out work of narrow sense being ground the method for face with the angle incision of regulation if be front end with this disc neighboring 6.And, only use in the common grinding operation of disc face 1A, on performance, can bring into play the grinding performance identical with existing Diamonid disk.

At part 1b, the part that forms point-like literal 27 is in a circumferential direction joined together harmoniously with the part maintenance at the partial function configuration diamond particles unit A of group that depends on periphery 1a by central part again.These diamond particles 2 itself use and the part 1a of close periphery and the identical diamond particles of part 1b of close central part, but, in the diamond particles sum, be fixed near the number of the part 1b of central part number and lack than the part 1a that is fixed in close periphery.Therefore the part 1b of close central part, only works in complementary grinding being the little position of working in common grinding work on the place.

On the other hand, in appearance, the density of the part 1b of close central part, density than the unit A of diamond particles group of the densification that can see at described part 1a by periphery is low, it is wider to distribute, and therefore, the point-like literal 27 (or figure) of formation is more showy.

The grinding Diamonid disk of the present invention of Gou Chenging not only is used in the grinding industry like this, and can play a role as a kind of rotary cut-off knife sheet, therefore can improve the versatility of grinding with Diamonid disk.And owing to form point-like literal or figure, producer's name and model are seen easily, therefore, also are desirable for the user.Again, form the part of above-mentioned literal or figure, owing to being is not easy the part that wears away along with effluxion, even when Diamonid disk itself goes out of use, also can see.Again, the part of above-mentioned literal or figure is arranged, its diamond particles is few, can reduce the waste of resource.

But, also can substitute the foregoing description, as Figure 11, shown in Figure 12, employing makes the outer edge of diamond disk sheet matrix 1 form flat condition, form in this outer edge simultaneously and have circle only to the outstanding 1D of circular expander portion of the back side one side, in the structure of the outer edge of the matrix 1 that comprises this bulge 1D configuration diamond particles 2.And what also can make around the above-mentioned bulge 1D diamond particles 2 that carries out is configured to successionally, also can take the intermittence configuration as shown in figure 11.With such structure, not only can carry out the grinding action on the narrow sense (meaning), and can carry out the rupturing operation on the narrow sense (meaning).Also have, in Figure 11, arrow R represents the direction of rotation of Diamonid disk.

Also have, as another kind of embodiment, shown in Figure 13,14, also can be omitted in the configuration of the diamond particles 2 of disc face 1A, and adopt to form structure to the outstanding bulge 1D of face side and rear side, as the Diamonid disk of cut-out on the narrow sense meaning or groove processing special use.

Again, as another embodiment, also can be shown in Figure 15,16, the matrix 1 of whole Diamonid disk is formed round tabular, as the Diamonid disk of cut-out on the narrow sense meaning or groove processing special use.Also have, in Figure 13,15, arrow R represents the direction of rotation of Diamonid disk.

In Figure 11～Figure 16, identical with Fig. 1～Figure 10 or corresponding primary structure is marked with identical reference symbol again.
