Due to the high heat resistance of bearing steels, many cutting tools such as traditional carbide tools, ceramic tools and traditional CBN tools do not allow the bearing steel to be processed very well. Ceramic tools and traditional CBN too...

At present, in the process of fine hardening steel, due to the small amount of machining allowance, the common CBN tools is a compound tool (as shown below), that is, the cutting edge and the body are not the same material, only the cutting...

Automobile gear material and processing technology The automobile gears are subjected to the heat treatment process to obtain better performance. The gears are used as the transmission and speed adjustment of the power in the mechanical dev...

Difficulties in hard turning gears after heat treatment (1) After the heat treatment, the hardness reaches HRC58-62, and the tool wears quickly, which affects the production efficiency; (2) Some gears have intermittent cutting conditions (t...
