The grinding projection 122 (with reference to Fig. 4 (b), (c)) for forming pin thread in the periphery of workpiece W is formed in the periphery of emery wheel plate 120.This grinding projection 122 is provided with multiple at the thickness direction (axis X 2 direction) of emery wheel plate 120 continuously, and these grinding projections 122 are separately positioned on circumference circumferentially whole around axis X 2.
Emery wheel plate 120 can be retired dynamic the orthogonal direction of axis X 2 (axis X 4 direction) is enterprising by the driving mechanism of not shown emery wheel supporting arrangement, and when forming pin thread in the periphery of workpiece W, moves to the assigned position of holding device 110 side.
Fig. 5 illustrates the figure workpiece W periphery employing emery wheel plate being formed to pin thread, a () is the figure of the state representing cutting starting position workpiece W being configured in the pin thread undertaken by emery wheel plate 120, b () is the figure representing state workpiece W being configured at the half-way of cutting pin thread in its periphery, (c) is the figure of the state representing cutting end position workpiece W being configured at the pin thread undertaken by emery wheel plate 120.
In the thread grinding device 100 of embodiment, do not change the position of the emery wheel plate 120 on axis X 2 direction, and by making workpiece W move to axis X 1 direction, form pin thread in the periphery of workpiece W.
Therefore, as shown in arrow mark y1 in Fig. 5 (a), after moving at the position making the emery wheel plate 120 rotated around axis X 2 never contact with workpiece W (with reference to solid line in figure) position (with reference to dummy line in figure) contacted with workpiece W, as shown in arrow mark y2 in Fig. 5 (a), (b), workpiece W is rotated while move to right direction in figure around axis X 1, thus forms pin thread in workpiece W periphery.
And, as shown in Fig. 5 (c), when the workpiece W of right side movement in figure arrives the cutting end position of pin thread, as shown in arrow mark y3 in figure, make emery wheel plate 120 from the position (with reference to dummy line figure) with absorption surface to not mobile with the position (with reference to solid line in figure) of absorption surface, terminate the formation of pin thread.
The processing employing the pin thread of this emery wheel plate 120 uses same emery wheel plate 120 repeatedly to carry out, and therefore, along with the processing of the pin thread carried out workpiece W, the shape of the grinding projection 122 of emery wheel plate 120 is worn and torn and changes.
Therefore, in thread grinding device 100, that carries out the pin thread of stipulated number adds man-hour at every turn, utilizes trimmer 130 abrasive sand wheel plate 120, with the shape (peripheral shape) of the grinding of trimming wheel plate 120 by projection 122.
Trimmer 130 is fixed on the dresser shaft 131 that extends along the axis X 3 parallel with axis X 2, is formed with the trim slots 132 of the shape of the grinding projection 122 for trimming wheel plate 120 in its periphery.
Multiple grooves 133 that this trim slots 132 is arranged continuously by the width at trimmer 130 are formed, and groove 133 forms the shape corresponding with the basic configuration of the grinding projection 122 of emery wheel plate 120 respectively.
And, when utilizing the peripheral shape of this trimmer 130 trimming wheel plate 120, make emery wheel plate 120 and trimmer 130 respectively under the state of axis X 2, axis X 3 rotation, emery wheel plate 120 is contacted with trimmer 130 outside the direction, footpath of axis X 3, thus, the shape of grinding projection 122 is repaired in the periphery of abrasive sand wheel plate 120.
In thread grinding device 100, the emery wheel plate 120 using the thickness W1 in axis X 2 direction to be in the margin of tolerance of regulation is formed with pin thread in the periphery of workpiece W.
At this, in emery wheel plate 120, owing to there is the deviation of the thickness W1 in the bending or margin of tolerance that its side 120a has, so the grinding by employing trimmer 130, the shape of grinding projection sometimes 122 is imperfect.
Fig. 6 is the figure of the change in shape that the grinding projection 122 that the thickness difference of emery wheel plate 120 causes is described, a () is the figure of the shape that the pin thread formed when the thickness of emery wheel plate 120 is the thickness Wstd of median is described, b () is the figure of the shape that the pin thread formed when the thickness Wstd of the Thickness Ratio median of emery wheel plate 120 is thick is described, (c) is the figure of the shape that the pin thread formed when the thickness Wstd of the Thickness Ratio median of emery wheel plate 120 is thin is described.
In addition, in figure 6, for convenience of explanation, the shape of the grinding projection 122 schematically showing emery wheel plate 120 and the pin thread being formed at workpiece W periphery.
As mentioned above, in the periphery of emery wheel plate 120, grinding projection 122 is arranged continuously throughout the total length of thickness direction.
As shown in Fig. 6 (a), when the thickness of emery wheel plate 120 is the thickness Wstd of median, the grinding projection 122 of emery wheel plate 120 both sides all becomes predetermined complete shape.Therefore, when using this emery wheel plate 120 at the periphery of workpiece W formation pin thread, left end becomes the complete thread of threaded top N1 and the thread groove portion N2 being formed with overall shape in the drawings.
Therefore, there is the other side's side component G of the negative thread screwed up with pin thread (in figure, with reference to dummy line) be screwed into the position of predetermined thread groove portion N2, so the distance of separation of the basic point W1 of the wide diameter portion of workpiece W and the other side's side component G becomes predetermined distance ta.
As shown in Fig. 6 (b), when the thick Rack a of the thickness Wstd of the Thickness Ratio median of emery wheel plate 120A, left end can form the grinding projection 122a of unscheduled imperfect shape in the drawings.
In this case, when using this emery wheel plate 120A at the periphery of workpiece W formation pin thread, due to the grinding projection 122a of imperfect shape, the side of the thread groove portion N2 of left end forms the thread groove portion N3 of unscheduled imperfect shape in the drawings.

As shown in Fig. 6 (c), when the thin Rack a of the thickness Wstd of the Thickness Ratio median of emery wheel plate 120B, in figure, the shape of the grinding projection 122b of left end is different from other grinding projection 122, becomes incomplete shape.
In this case, when using this emery wheel plate 120B at the periphery of workpiece W formation pin thread, due to the grinding projection 122b of imperfect shape, the side of the threaded top N1 of left end forms the thread groove portion N4 of unscheduled imperfect shape in the drawings, instead of the thread groove portion N2 of overall shape.
The shape of thread groove portion N4 changes owing to forming the deviation of the thickness of the emery wheel plate 120B of the grinding projection 122b of processing this thread groove portion N4.
Specifically, when the thickness Wstd of the Thickness Ratio median of emery wheel plate 120B is slightly thin, in figure, the grinding projection 122b of left end becomes the projection of close roughly overall shape.
When using this emery wheel plate 3 being formed with grinding projection 122b to form pin thread in the periphery of workpiece W, form the thread groove portion N4 close to overall shape in the side of workpiece W periphery, instead of the thread groove portion N2 of overall shape.
In this case, the negative thread of the other side's side component G can be screwed into the position of this thread groove portion N4, so the distance of separation of the basic point W1 of the wide diameter portion Wa of workpiece W and the other side's side component G becomes predetermined distance ta.
On the other hand, when emery wheel plate 120B thickness relative to median thickness Wstd than above-mentioned thinner, in figure, the grinding projection 122b of left end becomes the projection of imperfect shape.
When using the emery wheel plate 3 of this formation grinding projection 122b at the periphery of workpiece W formation pin thread, form the thread groove portion N4 of imperfect shape in the side of workpiece W periphery.
In this case, the negative thread of the other side's side component G can not screw up the thread groove portion N4 of this imperfect shape, and is screwed into the position of the threaded top N1 be adjacent.Therefore, the basic point W1 of the wide diameter portion Wa of workpiece W becomes the distance tb different with predetermined distance ta from the distance of separation of the other side's side component G.
Like this, when assembling the other side side component G and workpiece W, due to the deviation of the thickness of emery wheel plate 120B, the basic point W1 of the wide diameter portion Wa of workpiece W and the distance of separation of the other side's side component G there are differences, assembly failure.
Therefore, require adopt use trimmer carry out the emery wheel that grinds to define the screw thread that the other side's side component screws up in the periphery of workpiece time, the other side's side component screwed up from rotating shaft direction and the screw thread of workpiece is not subject to the impact of grinding wheel thickness, always can screw up and rotate axial assigned position.
Summary of the invention
The trimmer of thread grinding emery wheel of the present invention, the thread grinding emery wheel be provided with for the projection at Workpiece periphery grinding screw thread is ground, repair the peripheral shape being provided with described projection of described thread grinding emery wheel, wherein, described trimmer has the base portion rotated around the axle parallel with the rotating shaft of described thread grinding emery wheel, in the periphery of described base portion, the groove of shape corresponding to multiple and described projection is provided with continuously in described rotating shaft direction, and described groove is separately positioned on circumference circumferentially whole around described rotating shaft, in the multiple groove of described rotating shaft direction continuous print, the groove of at least one party of the groove being positioned at the axial one end of described rotation and the groove being positioned at the other end is formed more shallowly than other groove.

Therefore, when using the peripheral shape of this trimmer 5 trimming wheel plate 3, the grinding formed in the periphery of emery wheel plate 3, with in projection 35, forms the grinding projection 35A of imperfect shape with the projecting height that the grinding projection 35B than overall shape is low in the part of groove 54A grinding being trimmed device 5.
In addition, in the base portion 52 of trimmer 5, inclined plane 56 is provided with other groove 54B opposition side at the groove 54A relatively shallowly formed, when using the peripheral shape of trimmer 5 trimming wheel plate 3, being formed and comprising an inclined-plane of the grinding projection 35A of imperfect shape and the inclined plane 36 of the shape corresponding with the inclined plane 56 of trimmer 5.
At this, such as shown in Fig. 3 (a), when the thickness in axis X 2 direction of emery wheel plate 3 is the thickness Wstd of median, form the grinding projection 35A of inclined plane 36 and imperfect shape in the side of the workpiece W side (in figure left side) of emery wheel plate 3 continuously, and adjoin with the grinding projection 35A of imperfect shape and form the grinding projection 35B of overall shape.
At this, when the length of the inclined plane 36 by axis X 2 direction is set to Ws, the grinding projection 35A being positioned at the imperfect shape of the side of workpiece W side of the grinding projection 35B of overall shape is formed in the position that offset by predetermined distance Ws from the lateral margin 36A of emery wheel plate 3.And the grinding projection 35B of the overall shape adjoined with the grinding projection 35A of imperfect shape is formed in the position (Ws+S) that have left the length S on another inclined-plane of the grinding projection 35A of imperfect shape from lateral margin 36A further.
In addition, as shown in Fig. 3 (b), when the thick Rack a of the thickness Wstd of the Thickness Ratio median of emery wheel plate 3A, compared with the situation of Fig. 3 (a), the length forming the inclined plane in axis X 2 direction increases the inclined plane 36 ' of Rack a.
And, as shown in Fig. 3 (c), when the thin Rack a of the thickness Wstd of the Thickness Ratio median of emery wheel plate 3A, compared with the situation of Fig. 3 (a), form the inclined plane 36 of the contraction in length Rack a of the inclined plane in axis X 2 direction ".
At this, the length Ws in axis X 2 direction of the inclined plane 56 of trimmer 5 is set to the length of width (thickness) deviation of the emery wheel plate 3 that the intersection of the width (thickness) of the bending of the side 3a of Absorbable rod emery wheel plate 3 or emery wheel plate 3 causes.
Therefore, such as, in the scope that the thickness Wstd being in become median at the thickness deviation of emery wheel plate 3 supposes for benchmark in situation, no matter the thickness Wstd of the Thickness Ratio median of emery wheel plate 3 is thick or thin, the workpiece W of emery wheel plate 3 is all formed inclined plane 36,36 ', 36 ", the grinding projection 35B of overall shape does not damage shape respectively and makes.
Therefore, thicken or in thinning any situation, all make the grinding projection 35A of imperfect shape and the grinding projection 35B of overall shape with predetermined shape in the workpiece W side of emery wheel plate 3 with the thickness Wstd of median for benchmark at the thickness deviation of emery wheel plate 3.
Therefore, when using the emery wheel plate 3 shown in Fig. 3 (a) ~ (c), 3A, 3B at the periphery of workpiece W formation pin thread, be not subject to the impact of the thickness deviation of emery wheel plate 3, be formed with the pin thread of the thread groove portion N4 of imperfect shape on the side of the thread groove portion N5 of predetermined overall shape.
At this, be set to that the other side's side component G with the negative thread screwed up with pin thread is (in figure by the width in axis X 1 direction of the thread groove portion N4 by imperfect shape, with reference to dummy line) width that is not screwed into, the other side's side component G can be made to be screwed into the part of the thread groove portion N5 of predetermined overall shape, therefore, the basic point W1 of the wide diameter portion Wa of workpiece W and the distance of separation of the other side's side component G always become certain distance ta.
Therefore, even if when emery wheel plate 3 is thinner than the thickness Wstd of median, the position with the rotating shaft direction (axis X 2 direction) of the other side's side component G of the negative thread screwed up with the pin thread of the workpiece W being formed on the outer periphery pin thread also can not misplace, so suitably prevent the generation of the assembly failure of workpiece W and the other side's side component G.
In addition, that repeatedly carries out pin thread when using same emery wheel plate 3 adds man-hour, in grinding projection 35A, 35B that the periphery of emery wheel plate 3 is formed, wear and tear at the grinding projection 35A adding the imperfect shape being positioned at workpiece W side man-hour, and the grinding projection 35B of overall shape does not wear and tear.
At this, the grinding projection 35A of imperfect shape forms the thread groove portion N4 screwing up irrelevant imperfect shape with workpiece W and the other side's side component G, therefore, even if the grinding projection 35A of this imperfect shape weares and teares, the thickness in rotating shaft (axis X 1) direction of the thread groove portion N4 of the imperfect shape made by the grinding projection 35A worn and torn also narrows, thus can not affect the shape to the thread groove portion N5 screwing up relevant overall shape.
Therefore, even if like this, the basic point W1 of the wide diameter portion Wa of workpiece W and the distance of separation of the other side's side component G always become certain distance ta.
In addition, in emery wheel plate 3, the inclined plane 36 being formed at workpiece W side of the grinding projection 35A of imperfect shape is along with close workpiece W, and the direction to the rotating shaft (axis X 1) leaving workpiece W tilts.
Therefore, even if when workpiece W has and large-diameter portion that diameter than this working position large adjacent with the part (working position) of the formation pin thread of workpiece W, also can not make to disturb to the large-diameter portion of the workpiece W of rotating shaft (axis X 1) direction movement and emery wheel plate 3 and hinder the processing of pin thread.
As more than, in embodiments, the trimmer 5 of thread grinding emery wheel grinds the thread grinding emery wheel (emery wheel plate 3) be provided with for the projection (grinding projection 35) of the periphery grinding screw thread to workpiece W, finishing is provided with the peripheral shape of the grinding projection 35 of emery wheel plate 3, wherein
Above-mentioned trimmer 5 is configured to, there is the base portion 52 rotated around the axle (axis X 3) parallel with the rotating shaft (axis X 2) of emery wheel plate 3, in the periphery of base portion 52, the groove 54 of multiple shape corresponding with grinding projection 35 is provided with continuously in axis X 3 direction, and groove 54 is arranged throughout the complete cycle of the circumference around axis X 3 separately, in the multiple groove 54 of axis X 3 direction continuous print, the groove 54A being positioned at the one end in axis X 3 direction and the groove 54A being positioned at the other end is formed more shallowly than other groove 54B.
During such formation, when using the peripheral shape of trimmer 5 trimming wheel plate 3, in emery wheel plate 3, the both sides of multiple grinding projection 35B adjacent on rotating shaft direction form the grinding projection 35A of the imperfect shape that the groove 54A that relatively shallowly formed causes.
At this, when rotating the thickness deviation of axial emery wheel plate 3, the change in shape of the thickness direction (axis direction of axis X 2) of the grinding projection 35A of the imperfect shape that the groove 54A only relatively shallowly formed causes, the shape of the grinding projection 35B that other groove 54B causes can not be subject to the impact of deviation, and is always formed with complete shape.
In addition, as mentioned above, the grinding projection 35A of imperfect shape is formed in one end of the workpiece W side of emery wheel plate 3.Therefore, repeatedly carry out by utilizing emery wheel plate 3 processing the pin thread of workpiece W, even if the end of the workpiece W side in emery wheel plate 3 there occurs wearing and tearing, the grinding projection 35A of the imperfect shape of emery wheel plate 3 weares and teares, only change in shape, the impact that the grinding projection 35B of the overall shape adjoined with grinding projection 35A can not be worn, and always formed with complete shape.
Therefore, in the groove that the periphery of workpiece W is formed, when with only to groove (the threaded top N1 that the grinding at overall shape is formed by the part of projection 35B, thread groove portion N5) mode that screws up the other side's side component G is when setting, the other side's side component G always screws up identical position, therefore, the basic point W1 of the wide diameter portion Wa of workpiece W and the distance of separation of the other side's side component G are always certain distance ta.
Therefore, when the other side's side component G is screwed up with the screw thread of the periphery being formed at workpiece W, suppress the dislocation in axis X 1 direction of workpiece W, the generation of the assembly failure of the other side's side component G can be prevented.
In addition, be formed at trimmer 5 base portion 52 periphery trim slots 53 in, the groove 54A being positioned at the one end in rotating shaft (axis X 3) direction of base portion 52 and the groove 54A both sides being positioned at the other end are formed more shallowly than other groove 54B.
Therefore, by repeatedly carrying out the finishing of emery wheel plate 3, when the groove 54A of a side there occurs wearing and tearing, the groove 54A being such as positioned at workpiece W side only changes the installation direction of the trimmer 5 of dresser shaft 4 in the mode being positioned at opposition side, just can use same trimmer 5.
Therefore, it is possible to reduce the replacing number of times of trimmer 5.
At this, be temporarily described as follows situation, that is, in the grinding projection 35A of imperfect shape being formed at emery wheel plate 3 periphery, formed at the grinding projection 35A adding the end being positioned at workpiece W side man-hour with the shape identical with another grinding projection 35B.
When using the periphery machining screw of emery wheel plate 3 couples of workpiece W, the grinding projection effect of the end being positioned at workpiece W side is added to the stress in man-hour, so the grinding projection being positioned at the end of workpiece W side is owing to adding the load in man-hour and grinding projection is easy weares and teares than another.
Therefore, when repeatedly carrying out the machining of screw thread to the periphery of workpiece W, be formed in the thread groove of the periphery of workpiece W side, the groove formed due to the grinding projection of wearing and tearing is formed more shallowly than other groove, becomes incomplete shape.
In this case, the other side's side component G can not screw up preposition, produces assembly failure.
In embodiments, in trimmer 5, adjoin with the grinding projection 35B screwing up the overall shape of relevant thread groove portion N5 of workpiece W and the other side's side component G to formation and the grinding projection 35A formed with the imperfect shape screwing up irrelevant thread groove portion N4 is set, thus, the thickness deviation of emery wheel plate 3 only affects the grinding projection 35A of imperfect shape.
Therefore, when forming pin thread in the periphery of workpiece W, the thickness deviation of emery wheel plate 3 only affects the shape with the thread groove portion N4 screwing up irrelevant imperfect shape, and do not affect the shape to the thread groove portion N5 screwing up relevant overall shape, therefore, it is possible to reliably prevent the generation of assembly failure as described above.
In addition, groove 54A, 54A of relatively shallowly being formed at the base portion 52 of trimmer 5 are formed in the position that offset by predetermined distance Wt from lateral margin 55b, 55b of base portion 52, and this predetermined distance Wt is set to the inclined extent of the width (thickness) of the emery wheel plate 3 that the intersection of the width (thickness) of the bending of the side 3a of Absorbable rod emery wheel plate 3 or emery wheel plate 3 causes.
Therefore, when the thickness deviation of emery wheel plate 3 is in the scope that supposes for benchmark with the thickness Wstd of median, no matter the thickness Wstd of the Thickness Ratio median of emery wheel plate 3 is thick or thin, only change the predetermined distance Ws from the grinding projection 35A of the imperfect shape of emery wheel plate 3 to lateral margin 36A, can not impact the shape of the grinding projection 35B of the grinding projection 35A of imperfect shape or overall shape.
Therefore, functions and effects same as described above can be obtained more reliably.
In addition, in base portion 52, the wall portion 55 that the external diameter in the direction, footpath of axis X 3 is larger than the external diameter of the region Wb being provided with groove 54 is arranged with the lateral margin side of the groove 54A relatively shallowly formed is adjacent, the groove 54A side relatively shallowly formed in wall portion 55, with external diameter along with the direction diminished near the groove 54A relatively shallowly formed forms inclined plane 56.
When forming like this, in the emery wheel plate 3 using trimmer 5 to grind, formed in the workpiece W side of the grinding projection 35A of imperfect shape along with close workpiece W to the inclined plane 36 that the direction of the rotating shaft leaving workpiece W tilts.
At this, suppose when the groove 54A with trimmer 5 adjoins and is provided with the par (not shown) of even shape simply and do not arrange as described above inclined plane 56, then on emery wheel plate 3, form the par corresponding with the par of trimmer 5, and do not form inclined plane 36.
So, due to the degree of the thickness of emery wheel plate 3 or the deviation of installation site, the length of the par sometimes abutted to form with the grinding projection 35A of emery wheel plate 3.
In this case, when utilizing the periphery of emery wheel plate 3 couples of workpiece W to form pin thread, the par of emery wheel plate 3 and the wide diameter portion Wa of workpiece W may disturb and hinder Workpiece periphery formation pin thread.
Above-mentionedly to form like that, in emery wheel plate 3, when the workpiece W side of the grinding projection 35A in imperfect shape forms inclined plane 36, in order to the periphery screw cutting to workpiece W, when the direction of principal axis of the rotating shaft making workpiece W to this workpiece W (axis X 1) moves, the inclined plane 36 of emery wheel plate 3 avoids the wide diameter portion Wa of workpiece W, therefore, emery wheel plate 3 and workpiece W can not be made to disturb and hinder Workpiece periphery formation pin thread.
The predetermined distance Wt of the inclined plane 56 in axis X 3 direction sets as follows, that is, at least large than the error (dimensional tolerance of displacement+emery wheel plate 3 in axis X 2 direction of the error+grinding wheel spindle 31 of the installation site of grinding wheel spindle 31 in axis X 2 direction utilizing the thermal expansion of the thermogenetic emery wheel plate 3 of friction during trimmer 5 abrasive grinding wheel plate 3 to cause) in rotating shaft (axis X 2) direction in the error (dimensional tolerance of displacement+trimmer 5 in axis X 3 direction of the error+dresser shaft 4 of the installation site of dresser shaft 4 in axis X 3 direction that the thermal expansion of the thermogenetic trimmer of friction 5 when utilizing trimmer 5 abrasive grinding wheel plate 3 causes) in axis X 3 direction of the base portion 52 in trimmer 5 and thread grinding emery wheel (emery wheel plate 3).
When forming like this, trimmer 5 near emery wheel plate 3 time, the inclined plane 36 of emery wheel plate 3 necessarily contacts with the inclined plane 56 of trimmer 5, therefore, even if make trimmer 5 and the mutual rotating shaft (axis X 3 of emery wheel plate 3 due to above-mentioned error, axis X 2) position deviation in direction, also can be corresponding with the groove 54A of the inclined plane 56 being formed at trimmer 5 continuously and reliably form the grinding projection 35A of imperfect shape in the side in axis X 2 direction of emery wheel plate 3.
The groove 54A relatively shallowly formed has and clips the cross line of axis X 3 and the inclined plane 56 of symmetry, and the inclined-plane of lateral margin side in the groove 54A relatively shallowly formed is set to identical gradient relative to the gradient of axis X 3 and inclined plane 56 relative to the gradient of axis X 3, inclined plane 56 is positioned on the extended line on the inclined-plane of the lateral margin side of the groove 54A relatively shallowly formed.
When forming like this, form inclined plane 56 continuously with the groove 54A relatively shallowly formed of trimmer 5.When utilizing this trimmer 5 abrasive grinding wheel plate 3, corresponding with the groove 54A of trimmer 5 and form the grinding projection 35A of imperfect shape in the lateral margin 36A side of emery wheel plate 3, and formed and the inclination continuous print of grinding projection 35A, inclined plane 36 with inclined plane 56 equal angular.
Therefore, when utilizing the periphery of emery wheel plate 3 couples of workpiece W to form screw thread, the inclined plane 36 of emery wheel plate 3 is utilized to avoid the wide diameter portion Wa of workpiece W, therefore, even if there is deviation on the thickness direction of emery wheel plate 3, also can prevent the lateral margin 36A of emery wheel the plate 3 and wide diameter portion Wa of workpiece W from colliding.
In addition, except the projecting height ha outside radius vector direction, the shape for lugs of the grinding projection 35A of embodiment forms the shape identical with the grinding projection 35B of overall shape.But the shape for lugs of grinding projection 35 is not limited thereto, as long as the shape that can not screw up with the other side's side component G, also can be other shape.
Such as, also can as shown in Fig. 2 (c), grinding with in projection 35, at the grinding projection 35A of the side in the rotating shaft direction (axis X 2 direction) of emery wheel plate 3, from the angle of inclination of grinding with the change inclined-plane, midway of the inclined-plane f of projection 35A.Such as, also can, from the midway of the inclined plane of grinding projection 35A (angle of inclination on inclined-plane is θ 3), carry out grinding (transfer printing) with the shape of the inclined plane 56 (angle of inclination on inclined-plane is θ 1) with the trimmer 5 of the angle different from the tilt angle theta 3 on the inclined-plane of this grinding projection 35A.
In addition, groove 54A, 54A of relatively shallowly being formed of embodiment are formed in the position that offset by predetermined distance Wt from lateral margin 55b, 55b of base portion 52.But, even if when the groove relatively shallowly formed 54A, 54A are formed from lateral margin 55b, 55b of base portion 52 with offseting, time in the scope that the thickness deviation of emery wheel plate 3 is in supposition, even if there is deviation relative to the thickness Wstd of median in the thickness of emery wheel plate 3, only change the shape of the grinding projection 35A of the imperfect shape in emery wheel plate 3, just can not bring the impact of deviation on the shape of the grinding projection 35B of overall shape.
