Description

METHODS AND DIAMOND WHELL FOR USED TO ETHYLENE VINYL ACETATE AND WOOL}

The present invention relates to a polishing wheel for polishing a flooring material, such as marble, among diamond tools, and more particularly, it can be flexibly bent along a marble surface when polishing a non-flat uneven marble using the base material EVA material. And that the flat tip is thermally fused with the compressed wool to allow the wool to perform the proper polishing function even if the attached flat tip is worn away or lost.

Diamond or artificial diamond was invented in the 1950's, and is known as the hardest material on earth, and it has been used for cutting, grinding tools, and the like.

In particular, the artificial diamond (hereinafter referred to as "diamond") is widely used in the stone processing field for cutting and grinding stones such as granite and marble, and in the construction industry for cutting and grinding concrete structures.

In general, a diamond tool is composed of a cutting tip in which diamond particles are distributed and a metal core in which the cutting tip is fixed, and the grinding tip includes the grinding particles, a bond composition, a filler, and the like.

The grinding wheel (diamond grinding wheel) is a material that serves to support the diamond in the grinding tip, that is, depending on the resin bond wheel (resin Wheel), metal wheel (metal wheel) and vitreous bond (vitrified wheel) largely depending on the bond Diamond grinding wheels for cutting industrial tools and cutting tools such as drills, reamers and end mills are generally used as diamond grinding wheels using resins and metal binders.

The grinding wheel is exposed to new diamonds by friction with the workpiece during processing, where the bonds used as binders are worn by the grinding chips to facilitate the exposure of these diamonds and also prevent the diamonds from falling off easily. It plays a role of smoothing the workpiece by fixing the diamond.

In particular, the present invention relates to a disk-shaped diamond tool used for attaching diamond particles to a metal shank and polishing a brittle object such as stone, brick, concrete, asphalt, etc. There are various methods such as sintering method, metal fusion method, and metal electrodeposition method, but these methods have a problem in that the manufacturing process is complicated and costs and production costs are high.

On the other hand, the metal bond method, which is one of the diamond tool manufacturing methods, exhibits excellent performance in cutting and polishing stone and concrete due to its strong cutting force and long life, but it is difficult and difficult to manufacture a tool having flexibility in its components. Since it is combined with the body only by welding, there are various problems such as weight and production cost.

As such, because the metal shank is used to fix the tip of the diamond, the weight is too much, and when the user is mounted on the grinder, the weight becomes more heavy, making it difficult for the user to easily carry and use.

Moreover, when marble is used for the wall surface, it is also used to artificially form an irregular surface that is not polished, but the existing polishing machine cannot polish the surface having such a free curve.

It is an object of the present invention to provide a diamond polishing wheel having an uneven uneven surface of a surface to be polished and freely bent to be polished while maintaining such a free curved surface.

In addition, even if the diamond tip on one side attached to the polishing wheel is worn or dropped, the surface holding it instead of the diamond tip can perform the polishing function, so that the polishing wheel does not need to be replaced frequently due to partial dropout of the diamond tip. Another object is to provide a diamond polishing wheel of construction.

The above objects and technical features of the present invention will become more apparent from the detailed description for carrying out the invention with reference to the accompanying drawings showing the preferred embodiments.

The manufacturing method of the present invention according to the above object, the base molding step of making a base of the ethylene vinyl acetate resin material, and a wool attaching step of attaching and fixing the compressed wool to the upper surface formed base to form a wool layer, and the attached wool It is achieved by a diamond resin attaching step of attaching a diamond resin on the upper surface, and a fusion molding step of fixing the diamond resin and the wool layer by heat fusion.

On the other hand, the configuration of the present invention, the base is made of ethylene vinyl acetate resin material is formed in a circular shape, a wool layer of a suitable thickness to be fixed to the upper surface of the base, and the diamond is attached to the upper surface of the wool layer and fused with heat And a velcro plate attached to and fixed to the bottom of the base.

With the use of the present invention obtained through the above object and the means for solving the problem to achieve the object, the base of the polishing wheel having a diamond tip is freely bent along the free surface of the object to be polished and can be polished while maintaining the uneven free surface as it is. have.

In addition, even if the diamond tip of one side to be fixed to the polishing wheel is worn or dropped, the compressed wool performs the function of polishing instead of having to replace the polishing wheel frequently due to the partial drop of the diamond tip.

Hereinafter will be described in more detail with reference to the accompanying drawings showing an embodiment of the present invention.

The present invention relates to a polishing wheel that is used to polish or polish the surface of a stone, such as marble, among the diamond polishing wheels aging due to aging or bend again, and moreover, a stone having a free curved surface. The present invention provides a diamond grinding wheel that flexibly flexes along a curved surface without damaging the surface of the surface.

To this end, as shown in FIG. 1, first, a base preparation step (S100) of preparing a base 10 having an appropriate thickness formed of an ethylene vinyl acetate resin (EVA) material, and laminated compressed wool on an upper surface of the prepared base 10. Step of attaching the wool (S200) to form the wool layer 20 and the diamond resin attachment step (S300) and the wool layer (arranged in a suitable position using a diamond resin on the upper surface of the wool layer 20 using an adhesive) 20) and the diamond resin is manufactured by fusion molding step of integrally fixing by heat (S400).

A more detailed configuration of the present invention is made of ethylene vinyl acetate resin material and formed in a circular base 10, a wool layer 20 of the appropriate thickness is fixed to the upper surface of the base 10, and the wool layer ( It is composed of a diamond plate 30 is fixed to the upper surface of the 20) and fused with heat, and a Velcro plate 40 is fixed to the bottom of the base 10.

In the present invention as described above, the compressed wool layer 20 supporting and fixing the diamond plate 30 is firmly attached to the base 10, but the base 10 is made of an ethylene vinyl acetate resin (EVA) material, and is flexible. You can wheel.
