Description

This invention is mainly easy to cut when cutting fiber material, easy to sharpen, sharp cutting edge, knife, knife, shaving, file, grated, saw and other metal tools, electric chainsaw, electric cooking The present invention relates to a polishing machine, an electric polishing machine, and a manufacturing method thereof.
In addition, when making with a non-metal, a brushed raw material, brushes, a polisher, a plastic tool, and electric brushes are also included.

A knife with an uneven edge is already made.
In addition, a blade that has a pattern similar to Damascus steel on the surface of the blade is also made.
In addition, a generally used knife for bread cutting has a corrugated edge and a large saw-shaped corrugated blade.
For non-metallic materials, the production of brushed materials and brushes is also well known.

The following patent documents can be cited as known techniques relating to the present invention.
Patent Publication 2011-161064 Patent Publication 2012-192163

A blade having a structure in which metals of different materials are laminated together is known, and it is also well known that the sharpness is good. However, the process of manufacturing this blade is not easy, and it takes a lot of time and effort to produce a certain thing.
In addition, it was difficult to make a brushed material with a small size among brushed materials made of non-metallic materials.
Also, with brushes, it was common to embed several brushes together in one hole by embedding the brush, and there was no other method.

In the present invention, unlike the method of shaping a plate-like material generally used in blade production, a linear or fibrous material is wound around a kind of central axis called a core here. Then, the above problems are solved by a method of manufacturing a cutter having characteristics that are easier to mold by cutting the wound part and then forming the tip of the cutter.

Moreover, when this production method is applied, the cutting edge can be shaped into a saw shape or a file shape, or shaped into a wire brush shape.

In addition, when a non-metallic material is used for the core, the brush brush can be arranged like a belt unlike the conventional one, and a completely different brush can be produced.
At this time, by using a metal or a high hardness material for the fibrous material wound around the core, it is possible to make a small-sized and flexible belt-like chain saw.

By using a metal cutting edge made by this method, it is easier to sharpen, and when cutting fibers, a metal cutting edge that can be cut cleanly can be shaped.

Depending on the size and shape of the wire and fiber material to be wound, it can be made from small medical scalpel shape to shaving, sashimi knife size, file, grated, and saw-shaped cutting wood The blade can also be shaped.

If the core is a non-metallic material and the material to be wrapped is metal, you can make a grated, flexible saw, electric chain saw, etc.

If both the core and the material to be wrapped are non-ferrous materials, various sizes of brushed materials and brushes can be made by changing the size of the core and the material fibers to be wrapped.
In addition, brushes with a free pitch, electric brushes, etc. can be made.

The structure and production method will be described below using a simple diagram.

In the present invention, when roughly divided,
1. 1. Metal material is wound around the metal core 2. Wrapping a metal material around a non-metallic core There are three main styles of wrapping non-metallic material around a non-metallic core, each of which has a power unit attached.

Explaining the production method and the development method of the finished product,
Blade unit and manufacturing method 1-1. Core material: The core and wrapping materials are basically made of metal, the materials are arranged in a bowl shape, and the cutting edge unit has a very small cutting edge and can be embedded in the blade by forging and compression. Method.

2. Application of the blade unit and its deployment method 2-1.
A cutting edge unit with a core that is mainly non-metallic and made like a belt.
2-2.
A cutting edge unit made of a belt with a core that is mainly non-metallic and that is driven by power.

Core material: The core and wrapping materials are basically made of metal, the materials are arranged in a bowl shape, and the cutting edge unit has a very small cutting edge and can be embedded in the blade by forging and compression. Method.

Basically, a case 1-1 in which a fine sawtooth blade is manufactured using a metal material such as iron or stainless steel, and a blade, a saw or the like is manufactured will be described first.
Hereinafter, description will be made with reference to the drawings.

Here, a rod, a linear or belt-like, ribbon-like core (base material): A is prepared, and around it,
Wire-shaped wrapping material with higher hardness than the base: B,
A combination of wrapping materials consisting of a wire-like wrapping material having the same hardness as that of the base or having a hardness lower than B: C, or a material having a low height when wrapping: C ′, etc., is used regularly or using a guide 1 Wrap irregularly. See FIGS. 1, 2, 9, 10, and 11.

At this time, the core material A rotates in the direction of the arrow while being supported at both ends, and takes up the linear B, C, and the like. In FIG. 1, the core material is divided into two parts.
If the core A has a groove for guiding or an adhesive is attached to any of the core A, B, C, etc., the wires B, C are easily fixed.

There is also a method in which the core A is replaced with two rotating rods. See FIG.
Further, the core A is replaced with a fixed or non-rotating one, and the winding work can be performed by rotating the periphery of B and C. See FIGS.
In FIG. 1, the core A that is divided into two is used, but more cores can be arranged.

In FIG. 1, there is one soft material C for one hard material B, but the number of B is increased, soft materials C ′ are arranged like B, C, C ′, or It is also possible to change the winding height, diameter, etc. Reference FIG. 9, FIG. 10, FIG.

In addition, the winding arrangement is regular in FIG. 1, but can be irregular.
The results obtained vary depending on the size of the core, the thickness of the windings B and C, and the combination.

At the stage where the winding such as B is finished, the winding is cut using a laser or a diamond cutter at the position L in FIG.
3 and FIG. 4 show a fragmentary core A, a piece obtained by combining B and C with A on one side, and a cutting edge unit P, and FIG. 5 shows a cross section thereof.

Note that most of the figures used for the explanation here are those before compression, but in actuality these are formed by heating and compression in the process of welding and forging, so that the cutting edge portion is further reduced. The initial stage is shown in FIG.
The cutting edges are tilted by forging and compressing and are shaped to combine with each other. Various types of cutting edge units may be formed depending on the angle of compression, the difference in displacement, the degree of compression, and the like. See FIG.

In addition, although several winding lines are wound around the core here, it is almost the same even without a core, by pasting a wire made in a net shape instead of a winding line on the core and embedding it by forging. An effect can be obtained.
Also, the cross section of the winding line is a wide line or plate with a rectangular cross section rather than a line that is close to a circle or square, and at least two types of hard material and soft material are wrapped and wound to some extent There is also a method of winding so that the materials overlap.

Here, the wrapping material B can be substituted for the core.
Further, the same effect can be obtained even when the winding lines are wound so that they intersect each other, and the intersecting portions are welded and bonded together without the core. See ff in FIG. However, in terms of strength, it is stronger with the core.
Further, if a combination of some thin B or a combination of softer lines than B is used instead of a single line B, a finer blade edge unit can be produced.
Furthermore, the winding material B has a so-called marble-like, Baumkuchen-like layer in which materials of various hardnesses are mixed in layers in both the horizontal and vertical directions. By repeating the sharpening, the saw-toothed blade shape can be generated.

When the material B or C is a hard metal during winding, it is easy to bend if it is made flexible by heating it with a heating furnace, burner, arc, high frequency, or the like.
At this time, since B and C are also processed at a high temperature, it naturally contracts when the temperature reaches room temperature. Therefore, the core material A is also preferably heated.

By providing the guide 1, it is possible to control and adjust variously the pitch, angle and the like when winding the wire rods B and C around the base. In FIG. 1, the adjustment is performed with one guide 1, but it is more preferable to perform the adjustment with each wire to be wound.
FIG. 20 shows the condition of B when tilted and wound. By tilting, it can be seen that a sharp edge is formed at the tip even if it is polished horizontally.

After winding the materials: B and C around the core: A, A, B, and C are integrated by bonding, welding, or forging.
Before or after that, a part of the wound materials B and C is cut with a cutter, scissors, a diamond cutter, or a laser. L shown in FIG. 2 is a cut line. Here, the core is cut into two, and two cutting edge units P are formed.

P in FIG. 3 is an enlarged sketch of the cut piece and the blade edge unit. In FIG. 3, the core A is seen through, and this figure is a view seen from the core A side. FIG. 4 is a view as seen from the opposite side. In addition, although B and C are deformed by being pressed during forging or the like, they are described in the form before deformation here.

Next, the end surfaces of the hard material B and the soft material C shown in FIG. 3 are polished or chemically treated. See FIG. At the time of chemical treatment, if C has a low strength against chemicals, that is, it is easy to dissolve, it will decrease before B.
When polished or treated with chemicals, the end face 3 of the soft material is sharpened off compared to the end face 2 of the hard material. See FIG. 5 and FIG.
Thus, as a result, the end face 2 of the hard material B selectively protrudes.
6 in FIG. 5 and 6 in FIG.

At this time, although 4 and 5 seem not to be related so much, as shown in FIG. 5, the end face 4 of the hard material is effective for making the angle of the blade edge constant when polishing for positioning for polishing. Work.

Thus, when sharpened, as shown in FIGS. 6, 8, and 9, small saw-tooth-shaped cutting edges are continuously arranged in parallel on the cutting edge.
In addition, each is sharpened, so when cutting, it becomes easy to get caught in the fiber and easy to cut without slipping.

The order of sharpening is to grind the whole with a soft grindstone. In this case, since B is hard, it is not sharpened, and only the end face 3 of the material C is first worn away. Next, the end face 2 of B is ground with a hard grindstone such as a diamond grindstone.

When making a blade, the blade edge unit P is attached to the blade portion 7 of the blade by welding or forging to obtain a blade. 7 and 8. Here, the blade edge portion is exaggerated.
With the method of attaching the blade edge unit as shown in FIG. 8, even if the blade edge is sharpened and the blade is sharpened, the sawtooth shape of the blade edge does not change. The life of the blade is when the height of the blade unit is sharpened.
If the color of the hard wrapping material B is different from that of the core or the wrapping material C, it is convenient to know how far the blade is.

The blade tip unit P is compressed by forging, so that the blade portion becomes thinner and sharper.
As shown in the lower drawings in FIGS. 9 and 10, the thickness of the blade changes by deforming so as to be crushed during the forging.
When sharpening, it is mainly to sharpen the exposed surface of the end portion 2 of B, and it is not necessary to sharpen the opposite side.
FIG. 11 is a diagram in which the winding material B is belt-shaped, ribbon-shaped, that is, the winding height is small with respect to the winding width, and the winding width is wide, so that the winding material B is slightly overlapped and wound.
The bottom is crushed by press and forging. Actually, it is further thinned.

In this production method, a medical knife, knife, knife and the like can be produced. The maximum size of the wire material B is about 1 to 2 mm in diameter, and by arranging several or dozens of B in 1 mm, there is a characteristic that the shape of the saw blade becomes finer. The characteristics can be freely changed by determining the hardness, diameter, winding height, etc. of B, C, C ′.

In addition, there is a method of further controlling the thickness of B and C at the finish by shaping P once and then stacking it and applying further compression.
Materials such as iron, steel, and stainless steel are suitable for forging, but any material that can be forged can be used, and cast into softer materials such as tin, brass, silver, and aluminum. Or embedded in a synthetic resin.
The shape of the cutting edge unit and cutting edge changes due to forging and casting, but the hard material B is lined up in a thin line or ribbon shape, for example, parallel to each other at intervals like a ridge. The internal structure reached has not changed.

A method of manufacturing a cutting edge unit that embeds a wound material wound in a spring, coil shape, or loop shape into a metal or non-metal center material without using the center material when winding, and a knife, scissors, saw, grated Cutting edge unit that can be used for, etc.

FIG. 12 is an example in which the core material A is not used during winding as in Example 1-1. The rotor 10 is provided with two shafts: E. By rotating, the rotor 10 winds B through one guide.
In the drawing, only the hard material B is shown, but at this time, soft materials C and C ′ or materials of different sizes can be wound together.

The upper part of FIG. 13 shows the place where the wound B is removed and pressed flat. The result is a zigzag hard metal band. If this is left as it is or if it is folded in half as shown in Fig. 13 for example, the center material: soft metal that will be the core, or the blade edge of the blade is forged, cast, embedded, and sharpened to create a fine interrupted edge. The prepared blade unit can be manufactured.
The core material and core metal are not limited to iron, steel, and stainless steel, and even soft materials such as copper, aluminum, brass, tin, and silver have no problems, but rather soft enough to sharpen and are strong enough to support the cutting edge. If there is, there is no problem.
At this time, the core material: the core can be made of a synthetic resin.
FIG. 14 shows B and C rolled together and then pressed flat.
As shown by ff in FIG. 14, the contacts of the windings can be formed, and when this is welded and bonded, this loop can be put together, which is convenient.

The upper part of FIG. 15 shows a hard material formed into a zigzag and pressed. In the figure below, soft center material: when pressed into a core, it is partly pressed and bulges or pressure marks are applied so that B does not move easily.

FIG. 16 shows an example in which B, which is formed in a zigzag shape and has a compression mark, is embedded in a central material: core A, and the tip is cut and polished.
Core material: The core A can be made of a softer metal than B, but may be a soft synthetic resin typified by silicone rubber, or a hard synthetic resin such as polycarbonate.
It is also possible to produce a blade with a silver or black hard blade portion B arranged at the tip of a transparent polycarbonate blade tip.

If the central material core is a soft synthetic resin, it is possible to manufacture a blade edge unit P in which a blade is attached to a part of the belt.

Various cutting edge structure designs are possible by changing the thickness of the hard wire, the processing including bending of the tip, and the like, and an appropriate set of cutting edge units P can be created for the object to be cut.
Further, until now, B has been made of a hard material, but conversely, when B is made of a softer material than A, B is sharpened first, resulting in unevenness on the cutting edge. Even if this effect is used, a similar effect can be obtained.

FIG. 17 is a modification of the core A shown in FIG. 2 shown in the beginning, and is provided with a portion G on the side of A that can be discarded later. This G works in the same way as the core when the hard material B is wound around the core. After the hard material is wound, L falls off when L1 to L4 are cut with a laser or the like, and the hard material B as shown in FIG. It is possible to form the blade edge unit P in a form in which the front end portion B ′ protrudes.

In FIG. 16, the base of B is U-shaped and has a compression mark 11, so that not only metal but also non-metal can be firmly embedded.

12 to 16, B can be manufactured with a small diameter as in Example 1-1, but a thicker diameter is more suitable.
In FIGS. 16 and 17, the diameter of B is, for example, at least 0.1 mm to 0.4 mm, and when it is large, it is about 1 mm, and when the protruding width B ′ is increased, it can be used as it is as a saw.
With this saw, sharpening is completely different from conventional ones, and multiple blades can be sharpened at one time.

FIG. 18 shows that a larger diameter B is used, and the unit P in which the B is embedded is stacked and fixed, and can be formed into a file, a grater, or the like.
In both cases, the core and the winding material B can be molded using a synthetic resin, a synthetic rubber, or the like.

A method of manufacturing a cutting edge unit with a foldable center material and a large protrusion.

FIG. 19 is a diagram in which a folding core H is used.

In addition, here, what is inside the roll of winding B like H is called an inner core, and what is outside the roll of winding B like D is called outer core D.

In FIG. 19, the inner core H can be either metal or non-metal. In FIG. 19h, the material B is wound up in a state where the inner core H is V-shaped. When the winding is finished, H is folded and the top L of B ′ is cut with a laser or the like.
In addition, before and after this, in order to integrate and fix H and B, they are covered with an outer core D.

Both H and D can be formed of both metals and non-metals.
For metals, electric welding is possible, and for non-metals, an adhesive, or H and B can be bonded by heat.
Further, the Bs that are lined up or overlapped by compression may stick to each other.

What can be seen at the right end j of FIG. 19 is the blade edge unit P from which the B ′ portion protrudes.

FIG. 20 shows a state where the winding of B is inclined. In k, B ′ can be small, and since B is disposed obliquely, the blade B at the time of grinding has an inclined angle by simply polishing the end face 2 horizontally. This k is suitable for a saw.

In FIG. 20, l represents a case where B ′ is lengthened.
In this method, the magnitude of B ′ is affected by the magnitude of H. When H is folded in half, and the angle of the V-shape is 60 degrees, the size of B ′ is about half of the folded size of H.

Manufacturing method of the blade unit with a dummy rotating body.

FIG. 21 shows the combination of the inner core H and the winding dummy rotating body I, and winding B while rotating both I and H. Depending on the size of I, the size to be produced is limited. Manufacture is easy.
When the winding is completed, the core and B are fixed using the inner core H, the outer core D, and the like.

I may be a substantially cylindrical plastic, or may be a paper tube or a polystyrene foam.

A method of manufacturing a cutting edge unit that uses a fixed core when winding.

As a method of lengthening the protruding portion B ′, a method of using a winding machine having a fixed core F will be described.
22 and 23, F is a fixed axial core. There is an inner core H below F, and the inner core H moves in accordance with the winding speed of the winding.
Reference numerals 13 and 14 denote rollers. The top of 14 supports the top of the roll of the winding B, and the pitch of the winding is stabilized by moving the roller according to the winding speed of the winding. See FIG.
The fixed core F can be slightly vibrated to send out B and H.

In FIG. 23, the winding B rotates in the clockwise direction here, thereby creating a roll of winding on the fixed core.
A wrapping machine equipped with a bobbin-shaped B makes a roll of winding while rotating around F.

Either the inner core H or the outer core D is bonded to the winding B by 15 which is an electric heater, an ultrasonic bonding machine or an electric welding machine, just like the spine (D, H) and the rib (B) Fix B in shape.
The winding roll of B can be produced by either one of the inner core H or the outer core D.
Furthermore, it is not impossible for B to stick together by pressing B and crushing it sideways without the outer core and inner core.

In FIG. 24, o is where the winding wire B has been rolled, and p is where the inner core H is folded and wrapped with the outer core D. q is where B is cut at the center L. r is a cross-sectional view after completion of cutting.
r is a cross-sectional view, and the r-shaped one connected to form a brush is the finished blade edge unit.

Cutting edge unit whose core is mainly non-metallic and made like a belt

From here, the application of the blade unit and its deployment method will be described.
The name of the blade edge unit is easy to imagine that it is mainly made of metal and has a blade at the tip, but here it is also included in this name if it is made of non-metal and has no blade at the tip. I will explain.

The shape of r in FIG. 24 is representative of the cutting edge unit P whose core is basically made of nonmetal.
In this r, B can be a metal or a non-metal.
Also, the length of B ′ can be long or short. B is more stable in the flexible material if it has a compression mark 11 as shown in FIG.
Here, the inner core uses a foldable core H, but there is no problem with the inner core A having a structure that is not bent.
Here, the base supporting B is supported by A or H from the inside and D from the outside.
D ′ is the minimum thickness of the base.

First, a bristles can be made by bundling several layers of r.
Since a general brush is planted by embedding a brush in a hole, the brush can be pulled out by pulling strongly, but the brush brush made by this manufacturing method passes under the inner core H. Therefore, since it is necessary to destroy the inner core H or the brush in order to pull it out, the hair is not easily pulled out just by being pulled.

FIG. 25 is a view in which the finished r is cut into an appropriate size, aligned and bonded, and viewed from above. The side view is similar to FIG.
When B 'is shortened, it is filed and slips, when it is slightly enlarged, it is grated, and when B' is lengthened, it becomes a brush.

FIG. 26 shows r formed by winding a plurality of Bs made of a synthetic resin, in this case, three bundles around a core, and alternately meshing them so as to be close to one line. Is a brush that is formed by rounding the ones molded so as to form a flexible belt.
It can be stretched and used as a belt, or it can be used like a regular hairbrush.
The brush tip is cut by a cutter or a laser, but laser cutting can be softly deformed by heat.

In FIG. 26, if B is made of one metal and a blade is attached to the end portion, a flexible knife can be obtained, and if a diamond grindstone is attached to the tip portion, a polishing belt is obtained.

There is a technique to knead glass fiber into the rubber of the shoe sole so that it does not slip on the frozen road surface, but with this r, any of the cores A, H, D is rubber or synthetic rubber, and B is a metal Because it is one of hard synthetic resin, glass fiber, etc., the same sliding effect against ice can be obtained, and since all B end faces are configured to face in one direction, You can make materials with little waste.

In r of FIG. 24, when H and D are both metals and B is also a metal, when the upper body r is formed as shown in FIG. 25 and FIG. Are arranged side by side in the form of a plate, from which a brush-like B grows. Since this has high heat conductivity, it can be used, for example, for the bottom of a kettle, a heat transfer part such as an air conditioner, a heater, or a cooler, or a heat exchanger part.

The characteristics of the cutting edge unit are completely different depending on the materials and sizes of the cores A and H, the material of the winding material B, the length of B ', the shape of the tip of B, and the processing of the tip. You can aim.

By reducing the diameter of the brush brush, you can make a brush of a small size that could not be made until now. Also, there is a feature in the way the brushes are arranged, both of which have a structure and form that have never existed, and can be used for new purposes.

In addition, the core is a thin fiber, and the thin fiber is wound as B, and the tip is not cut, or by twisting the cut one, a raised fiber, something like a raised cloth, a string-like file, a saw Can also be produced.

FIG. 27 is an explanatory diagram of a shaving blade. Combining the two above gives the bottom blade.
By adjusting the windings B, C and the like, the cutting edge unit can create a gap between the cutting edges as shown in the above figure. If a cutting edge unit having kk that fits in the gap jj or a part having a shape corresponding to the cutting edge unit is made of plastic or metal, it is possible to make a shaving blade having an image of a blade at the base of a comb.
In addition, since this blade unit is easy to bend, it is easy to fit the skin.
Moreover, since the blade tip has a length of mm corresponding to the comb teeth, it can be shaved without damaging the skin.

Cutting edge unit made of a belt whose core is mainly non-metallic and moves by power

S, t, and u in FIG. 28 are explanatory diagrams when r in FIG. 24 is attached to an annular cocked belt.
These utilize the feature that r is belt-shaped, and H and D are attached to a toothed belt 16 made of a non-metallic and flexible material that does not stretch. Yes.
In s, D, B, and H are attached to the side of the belt 16.
At t, the arrangement of B meshes with each other and is aligned in a straight line, and a cocked belt and a gear meshed with the cocked belt can be seen below.
In u, the structure is such that the gear is directly applied to the portion B, which is almost a combination of a chain and a gear.

Here, if B is made of metal and a blade is attached to the tip, a small chainsaw and grater can be produced.
If the tip of B is a grindstone or diamond grindstone, an electric belt-type grinder is obtained.
When B is made of synthetic resin, an electric brush, an electric toothbrush or the like can be made, and an electric cooker can also be made.
In either case, if the size of B is increased, an existing one can be obtained, and if B is decreased, an electric brush, an electric polishing machine, or an electric saw having an existing shape is obtained.
It is also possible to actually configure the base part and the AD part with a chain, and the durability can be improved.

In addition, it is possible to manufacture tools and brushes that vibrate ultrasonically by attaching them to a vibrator such as an ultrasonic motor instead of starting the motor directly.

Incidentally, at t and u in FIG. 28, the belt moves in the opposite direction so as to fit the palm between the right and left sides of the gear because B is gathered on one side of the belt.
There is no unprecedented use of such a blade edge that moves in the opposite direction on each side. If it is desired to set the direction to only one direction in this state, there is a method in which the top of B on one side of the row is raised and the other is moved low.

Cc of FIG. 29 is similar to r of FIG. 24, but the bottom of B is shaped like the lower part of U in the Roman letter is horizontal, or shaped like a staple, and the core part is Since the gg axis is not parallel to the rotation axis, it is made so that B does not easily fall down, and a general arrangement such as ee in FIG. 30 is possible. Yes.

In ee, it is also possible to attach a cutting edge or the like on B.

Some of the cutting edge units shown here have a core having a metal center and B being a cutting edge.
In the present invention, when roughly divided,
1. 1. Metal material is wound around the metal core 2. Wrapping a metal material around a non-metallic core There are mainly three styles of non-metal wrapping around a non-metal core, each with a power unit attached.

Here, once again, the basic concept of the present invention is summarized.
1. For metal core + metal wrapping material.
There is a core at the center, and a hard material is wound around or next to it in a coil or loop, and if possible, it is bonded.
A coil-shaped or loop-shaped material is cut with a laser or the like, and a U-shape is connected on one core, and this is a cutting edge unit.
The cutting edge unit is manufactured as it is or embedded in the tip of the cutting tool by forging, welding or the like to manufacture the cutting tool.
Wound material with a short projecting tip or some material wound and sharpened becomes a knife, knife, etc. Moreover, the thing with a large magnitude | size of a protrusion part becomes a saw, a file, and a grater.

2. Non-metallic core + metal wrapping material.
If it is a hard non-metallic material, the thing close | similar to the case of a metal core is made.
If it is a soft non-metallic material, first, its flexibility is used to form a belt-like knife, knife, saw, belt-like file, or the like.
Next, with the belts stacked, it becomes a wire brush, a file, a grater, a non-slip shoe sole, or the like.

3. For non-metal core + non-metal wrapping material.
It becomes a belt-like brush.
With the belts stacked, they become brushes, grated glasses, non-slip soles, and so on.
When the size of the core is the size of the yarn and the size of the wrapping material is also the size of the yarn, it becomes a raised fiber.

4). When the above 2 or 3 is combined with a disk or an annular pulley belt or cocked belt and moved by power, it is used for an electric knife, a small electric chain saw, an electric polishing machine, an electric toothbrush, various cookers, etc. Become.
There is a possibility.
All of these have a new outlook and are considered to have high industrial applicability.
