Progress in the application of superhard abrasives at home and abroad in the past ten years

Due to its high hardness and excellent wear resistance, diamond and cubic boron nitride (CBN) abrasives are widely used not only in the processing of hard and brittle materials such as ceramics, glass, stone, semiconductor, etc., but also as semi-permanent and ultra-high-speed abrasive tools. In general, the processing of steel plays an increasingly prominent role. It can be trimmed for a long period of time and is ideal for high-precision, high-precision grinding in automated, semi-automated and multi-machine management production. Grinding wheels with a single layer of CBN plated on steel-based discs are widely available in advanced technology countries. It is difficult to see the use of ordinary abrasive grinding wheels in the grinding workshop of Japanese tool manufacturers. The use of strong honing of diamond or CBN honing sticks, the use of electroplated CBN grinding wheels or low-speed grinding of the tooth surface, and the high-speed grinding of threads with CBN grinding wheels are examples of new applications for superabrasives.

In line with the popularity of superhard abrasives, the practical superhard abrasive dressing technology has matured. The data of superhard abrasive grinding has been abundant and can guide the production. The grinding amount and cooling finishing conditions have been standardized.

In addition to the above aspects, high-efficiency grinding of hard and brittle materials such as engineering ceramics and outstanding advances in precision and ultra-precision grinding technology; "SG" abrasives with micron-sized polycrystalline composition, hollow spherical ceramics for abrasive belt polishing Abrasives, spherical abrasives containing fine diamond abrasive grains for superhard materials, and many other new abrasives, as well as ultra-fine polishing plastic coated film strips, Nieuw brush grinding wheels containing abrasive micro-powder, cast iron bond grinding wheels, etc. The emergence of new abrasive tools; the production of centimeter-size large-diameter synthetic diamond; abrasive jet processing, abrasive hydrojet machining, viscoelastic abrasive flow extrusion honing, integral forming grinding, magnetic grinding, magnetic fluid precision grinding, low stress The emergence and development of a large number of new grinding technologies, such as grinding, ultra-high-speed grinding and extremely low-speed grinding, are also prominent aspects of the development of foreign grinding technology in recent years.
