The cubic boron nitride particles of the cutting piece adhere to the surface of the ordinary cutting piece and have a very thin layer. The toughness, hardness and durability of the <a href="https://www.auroraabrasive.com/6-inches-aluminum-oxide-abrasive-metal-cutting-disc/">6 inch es cutting disc</a> are 100 times that of the corundum cutting piece, which is most suitable for processing high hardness, high viscosity and high temperature strength. High-hardness, low thermal conductivity steel and high-speed or ultra-high-speed grinding. Its application range complements synthetic diamonds. Diamond cutting discs have unique effects when grinding cemented carbide and non-metallic materials, but they are not effective when grinding steel, especially when grinding special steel. Cubic boron nitride cutting sheets are nearly 100 times more efficient than corundum-cutting sheets, and five times higher than diamond-cut sheets, but the brittle material is less than diamond. Metal processing WeChat, the content is good, it is worthy of attention.
The choice of cubic boron nitride cutting sheets is similar to the choice of diamond cutting sheets. However, in the selection of binders, most of them are resin binders, followed by electroplating and metal binders. Ceramic bond CBN cutting sheet is mainly used for the grinding of difficult-to-machine ferrous metals such as titanium alloy, high-speed steel and malleable cast iron. The resin bond CBN cutting sheet is suitable for grinding ferromagnetic materials and is an ideal choice for processing steel. The concentration of CBN cutting discs is generally economical and reasonable between 100% and 150%. It cannot use ordinary cutting fluid and requires special cutting fluid.
Selection of atmospheric hole cutting sheets
Atmospheric hole cutting sheets have the advantages of being difficult to be blocked, high durability and strong cutting ability during grinding. Suitable for rough and fine grinding of non-metallic materials such as soft metals and plastics, rubber and leather. At the same time, it has the characteristics of fast heat dissipation, so it has good effects in grinding some heat-sensitive materials, thin-walled workpieces and dry grinding processes (such as sharpened carbide tools and machine guides).
The atmospheric hole cutting piece and the general ceramic <a href="https://www.auroraabrasive.com/14-inches-cutting-disc/">high quality cutting disc supplier</a> are basically manufactured in the same manner. The difference is that a certain amount of porogen is added to the furnish, which is completely volatilized or burned before the dicing sheet is sintered, thereby producing an atmospheric pore.
The production range of atmospheric hole cutting sheets is as follows: abrasives are generally selected from carbides and corundums, such as black silicon carbide (C), green silicon carbide (GC) and white corundum (WA). These abrasives have high hardness. Slightly brittle and sharp, with good thermal and electrical conductivity; abrasive particle size (36#~180#); binder (ceramic bond); hardness (G~M levels); shape (flat, cup, bowl or Disc shape, etc.; pore size (about 0.7~1.4 mm).
