Abstract

PURPOSE:To uniformly disperse grinding members in an arbitrary distribution state, by working a grinding member holding part consisting of a groove or holes for growing the grinding member on a base member and carrying out the gas-phase growth of the grinding member on the holding part, when the adhesion preventing processing for the grinding member is applied on a grinding wheel. CONSTITUTION:In the manufacture of a cutting grinding wheel, segment shaped base members 6 which are formed by dividing an inner cylinder to plural pieces are manufactured. Then, after a paint film 8 for preventing the adhesion of a grinding member 2 is formed on the periphery of the base member 6, a groove (or a number of small diameter holes) 7 as a holding part for the grinding member 2 is worked on the base member 6. This groove 7 is formed by the working in a straight lime from or in a curved line form in the direction forming a prescribed angle for the radial direction or deformation direction of the grinding wheel 1. Then, the grining member 2 such as diamod is gas-phase-grown bv the CVD method inside the groove 7 on which the film 8 is removed. Then, a necessary grinding wheel 1 is finished by attaching the a pluralty of base members 6 which are obtained by removing the film 8 onto the outer periphery of a body 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a grinding wheel.

[0002]

2. Description of the Related Art A conventional grinding wheel 1 is shown in FIG.
It has a structure in which an abrasive material 2 formed in an irregular shape is fixed by a binder 3. Incidentally, depending on the type of the binder 3, there are some in which the pores 4 are formed as shown in FIG. In such a grinding wheel 1, when the abrasive material 2 is worn or crushed by grinding and becomes small, the holding force of the binder 3 becomes weak and the abrasive material 2 falls off due to the action of grinding resistance. As a result, the dropped abrasive material 2 may be sandwiched between the grinding wheel 1 and the material to be ground, and scratches may occur on the surface of the material to be ground. ◆ As a method to solve the above problems,
The present inventor has proposed a grinding wheel 1 in Japanese Patent Application No. 3-16676, in which the abrasive material 2 is formed into a fibrous or thin film shape so as not to fall off even if the abrasive material 2 is worn.

[0003]

When the grinding stone made of the above fibrous or thin film abrasive material is used, the abrasive material does not fall off and scratches on the surface of the material to be ground can be prevented. However, it is difficult to uniformly distribute the abrasive material in the grinding wheel, and it is difficult to ensure the uniformity of the distribution of the abrasive material in the grinding wheel and the uniformity of the quality between the grinding wheels. ◆ The object of the present invention is to solve the above-mentioned problems and prevent the abrasive material from falling off.
Moreover, it is an object of the present invention to provide a method for manufacturing a grinding wheel that allows an abrasive material to be uniformly distributed in the grinding wheel.

[0004]

Means for Solving the Problems The above-mentioned problems have been solved by providing an abrasive material comprising grooves or holes for producing the abrasive material on the base material of the grinding wheel after the abrasive material adhesion-preventing treatment is applied to the base material. The problem can be solved by processing the holding portion and vapor-growing the abrasive on the abrasive holding portion.

[0005]

[Function] Since the abrasive material holding portion is processed on the base material,
The abrasive material can be uniformly distributed in any distribution state. ◆ Because the abrasive material is made to grow in vapor phase on the abrasive material holding part, it is possible to form a thin plate-shaped or rod-shaped abrasive material that has the same shape as the abrasive material holding part, and prevent the abrasive material from falling due to wear. can do.

FIG. 1 is an explanatory view of a grinding wheel manufacturing process showing a first embodiment of the present invention. In the figure, 1 is a grinding wheel, 2 is an abrasive material, 5 is a disk-shaped body, 6 is a segment-shaped base material, 7 is a groove processed in the base material 6, and 8 is an abrasive material 2 It is a film for preventing adhesion to the material 6. ◆ Then, a grinding wheel is manufactured according to the following steps. That is, step A: a segment-shaped base material 6 obtained by dividing a cylinder into a plurality of parts.
To produce. ◆ Step B: A film 8 is formed around the base material 6 to prevent the adhesion of the abrasive 2. The film 8 may be made of paint, for example. ◆ Step C: The groove 7 which becomes the holding portion of the abrasive 2 is formed in the base material 6. The groove 7 may be processed not only in the radial direction of the grinding wheel 1 or in a straight line forming a predetermined angle with respect to the radial direction, but also in a curved shape. Further, the width of the groove 7 is usually the grinding wheel 1
It is about the diameter of the granular abrasive used for. ◆ Step D: Abrasive material 2 (for example, diamond) is vapor-phase grown inside the groove 7 by the CVD method or the like. At this time, the abrasive material 2 selectively grows only inside the groove 7 where the film 8 is removed. ◆ Step E: The film 8 is removed. ◆ Step F: A plurality of base materials 6 are adhered to the outer periphery of the body 5 to manufacture the grinding wheel 1. ◆ In this example, the base material 6 has grooves 7
However, instead of the groove 7, a large number of small holes may be formed. Further, here, the segmented base material 6 is adhered to the body 5 to manufacture the grinding wheel 1. However, when manufacturing the grinding wheel 1 having a small diameter, the groove 7 or the small diameter hole is directly formed on the body 5. It may be processed so that the body 5 and the base material 6 serve as both.

FIG. 2 is an explanatory view of a grinding wheel manufacturing process showing a second embodiment of the present invention. Note that the reference numerals are the same as those in FIG. Further, the drawings of the same steps as in FIG. 1 are omitted. ◆ Then, a grinding wheel is manufactured according to the following steps. That is, step A: the base material 6 is manufactured. ◆ As shown in the side view, the base material 6 is a thin disk that also has the function of the body 5.
◆ Step B: Form the film 8 on the substrate 6. ◆ Step C: The groove 7 is processed. The groove 7 may be processed not only in the radial direction of the grinding wheel 1 or in a straight line forming a predetermined angle with respect to the radial direction, but also in a curved shape. Also, the groove 7
Is approximately the diameter of the granular abrasive used for the grinding wheel 1. ◆ Step D: The abrasive material 2 is vapor-phase grown inside the groove 7. ◆ Step E: The film 8 is removed. ◆ Step F: A plurality of base materials 6 are laminated by adhesion or the like. ◆ When laminating, the phase of the abrasive material 2 formed on each base material 6 may be shifted by a predetermined amount, or the base material 6 in which the groove 7 is not processed (the base material in the state of step A in FIG. 2). (Material) may be inserted between the base materials 6. Further, a plurality of base materials 6 are laminated, but a single material may be used. In addition, in the above two embodiments, the abrasive material 2 was filled in the groove 7, but FIG.
As shown in, the abrasive material 2 may be vapor-phase grown only on the side surface of the groove 7. By doing so, the holding strength of the abrasive material 2 becomes weak, but there is an effect that a large chip pocket can be secured. Further, although the case of the flat grindstone has been shown, it goes without saying that the present invention can be applied to a grindstone of other shapes.

[0008]

As described above, according to the present invention,
The abrasive material can be uniformly distributed in any distribution state. Therefore, there is an effect that it is possible to manufacture a grinding wheel with uniform performance and no drop of the abrasive material.
