The present invention relates to an apparatus for processing abrasive products, in particular grouped abrasives comprising grouped abrasives (aluminum oxide, silicon carbide, alumina zirconia, and abrasives in which one or two or more abrasives of ceramic type are used in groups). It relates to a processing apparatus of.

A general abrasive product is composed of three elements, such as the substrate 10, abrasive 20, adhesive 30, 31, etc., as shown in Figure 1, the abrasive 20 is aluminum oxide, silicon carbide, alumina zirconia, And a single layer structure using a ceramic kind.

However, the conventional abrasive products are made of a single component is easily worn by repeated use, there was a problem that the grinding performance is sharply reduced in proportion to the use time.

In order to improve this, as shown in FIG. 2, a plurality of abrasives 20 are mixed to form a predetermined size or more, and then simply produced on the upper side of the substrate 10 by the production adhesive 30 and the coating adhesive 31. Although the attached product has been released, the product has a problem in that the separation of the abrasive occurs when the bond strength between the abrasive is weak.

In addition, irregularities in the shape and size of the mixed abrasives to form a non-flat polishing layer in the polishing process, thereby the metal [SUS-304, 400, carbon steel, alloy steel] and non-ferrous metals [Titanium, natural marble, Artificial marble, aluminum, etc.] There is a high possibility of defective products due to roughness at the time of polishing.

The present invention has been made to solve the above problems, the processing apparatus that can provide an improved grouping abrasive product having a uniform roughness without the separation phenomenon of the abrasive when attaching the grouping abrasive on the upper side of the substrate To provide.

In addition, by adjusting the height of the grouping abrasive irregularly formed in the grouping abrasive product by a flattening processing apparatus including a gap adjusting part and a processing part to improve the loss of the roughness (Loss) due to poor roughness and improved productivity It is to provide a processing apparatus that can provide a product.

According to one embodiment of the present invention, the abrasives grouped on the upper side of the substrate (aluminum oxide, silicon carbide, alumina zirconia, and abrasives of one or two or more of the ceramic type grouped together) are firmly prevented from being separated during use. I can attach it.

In addition, according to an embodiment of the present invention, roughness defects may be improved by forming a flat grouped abrasive material by constantly maintaining an irregular height of the grouped abrasive material.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 3A, the grouped abrasive product according to the present invention includes a substrate 10 and a production adhesive 30 in the same manner as a conventional product, and the abrasive attached to the production adhesive 30 is made of aluminum oxide, One or more of silicon carbide, alumina zirconia, ceramics, garnets, and artificial diamonds is composed of a grouping abrasive 100 which is mixed with a binder (not shown) and subjected to extrusion and crushing.

In this case, the binder is a two-component synthetic resin and a hardening accelerator, a low boiling point Solvent (Solvent) is mixed as a two-component synthetic resin to enhance the bonding strength between the abrasives, and can have a strong bonding force in a small coating amount It is preferred that it be made of high solids.

The two-component synthetic resin, which is a component of the binder, is used by mixing a main component with a curing agent or a curing accelerator. Since the curing agent is added, it is a thermosetting resin which can be dried by inputting less heat energy than the one-component synthetic resin.

Of course, if necessary, one-component synthetic resins may be used, or may be made of the same components as the production adhesive 30.
