Product Advantages
Special heat treatment design according to the different needs of specific industries for gears，It mainly includes induction single-tooth quenching and induction-type integral tooth quenching. Single-tooth quenching is further divided into tooth surface quenching (FH) and tooth root quenching (GH).After quenching, tempering treatment is carried out to make the surface hardness and the depth of the hardened layer meet the design standards.
The most advantageous is the special process of integral tooth quenching, which can improve the transmission efficiency, increase the wear resistance and impact resistance of the tooth surface. So as to meet the needs of customers.
Improve the machining program, shorten the machining path, reduce the clamping time of the tool, and improve the machining efficiency.
Improve the design tool processing technology to meet the different needs of customers, thereby increasing market share. For example: processing of wind power, medical equipment, military and other supporting products.
The development and production of magnetic chucks to change tooling can effectively solve the problem of deformation of slewing bearings.
