Superabrasive cutting discs made of diamond or cubic boron nitride (CBN) abrasives have been widely used in all aspects of grinding because of their excellent grinding properties. Diamond 6 inch es cutting disc are special effects tools for grinding hard and hard materials such as cemented carbide, glass, ceramics and precious stones. In recent years, with the rapid development of high-speed grinding and ultra-precision grinding technology, higher requirements have been placed on the cutting piece. The cutting piece of ceramic and resin bonding agent can not meet the production needs, and the metal bond cutting piece It has a wide range of applications in production due to its high bonding strength, good formability and long service life.
1. Sintered metal bond cutting sheet
It is made of high-temperature sintering method using a metal such as bronze as a binder. It has high bonding strength, good formability, high temperature resistance, good thermal conductivity and wear resistance, long service life and can withstand large loads. Since the cutting piece inevitably has shrinkage and deformation during the sintering process, the cutting piece must be shaped before use, but the cutting piece is difficult to trim. At present, the cutting method of the cutting piece commonly used in the production is not only time-consuming and labor-intensive in trimming, but also the diamond particles are more detached during the trimming process, and the trimming cutting piece itself consumes a large amount, and the shaping precision is low.
In recent years, scholars from various countries have successively carried out research work on the application of special processing methods to trim metal bond diamond cutting sheets, mainly including electrolytic dressing method, electric spark trimming method and composite trimming method. Electrolytic dressing method is fast, but the shaping precision is not high; the electric spark dressing method has high precision, can be shaped and sharpened, but the shaping speed is slow; the composite dressing method has electrolytic sparking composite trimming method and mechanical chemical compound trimming method. Etc., the trimming effect is better, but the system is more complicated, so the dressing problem of the sintered diamond cutting piece is still not well solved. In addition, since the manufacturing process of the fiber cutting disc Chinese supplier determines that the surface topography is random, the geometry and distribution of the abrasive grains and the height of the cutting edge are inconsistent, so only a few high cutting edges are cut to the workpiece during grinding. Further improvements in grinding quality and grinding efficiency are limited.
