Selection of Corrugated Cardboard Slitting Thin Blade Wheel

The slitting thin knife grinding wheel is a resin bonded grinding wheel for slitting blade, which is characterized by good self-sharpening, less blocking during grinding, less heat generation, high knife edge finish, sharpness, and high grinding efficiency. Grinding Tools The grinding wheel of steel thin knives is mainly made of cubic boron nitride (CBN), which is called cubic boron nitride grinding wheel. Grinding wheels for hard alloy thin knives are mainly made of "Jerusalem" (JR), which is called a diamond grinding wheel.

Judging directly from the appearance of the type of grinding wheel: tool steel thin grinding wheel is mostly used in green and black, tungsten carbide grinding wheel is iron red.

The above two kinds of grinding wheels are difficult to distinguish its material appearance. Different materials have different uses. Can not be replaced with each other. The color of the grinding wheel plays a minor role in the grinding effect of the grinding wheel. It is only an auxiliary material. At present, China's production of grinding wheels is generally green, black, iron red three colors. Because of the differences in the raw materials used by the grinding wheels produced by various manufacturers, there are certain differences in the color of the wheels produced by the formula and the process, but the use results are basically the same. When purchasing, it mainly depends on the concentration of its raw materials. The concentration of such grinding wheels in China is generally 75%. There is the size of the grinding wheel for paper box slitting blades raw material. Generally, the grinding wheel tool steel grinding wheel uses 170#-200#, and the cemented carbide thin knife grinding wheel has the grain size between 240#-320#.
