The main materials of wind power bearings will be 42CrMo, and the hardness after heat treating will be HRC47~55, and the machining site is the raceway. In the past, the manufacturers usually use ceramic insert for finishing process in the p...

Synchronizer, as one of the most important in the gearbox, is used for buffering the speed to avoid fight teeth when change the grade. In order to ensure the abrasive resistance of the synchronizer, the manufacturers usually use heat treatm...

The advantages of superhard cutting tool is avoiding grinding, and improve the production efficiency. Hard turning can realize high speed machining, and 80% of the heat will be taken away together with the chips, which will help save the co...

Gears, were machined with grinding process to meet the surface quality and size precision requirements because of its high hardness after heat treatment. With the development of the society, grinding process already cant meet the customers...

As we all know, with the increasing quality requirements on the gears and the raising costs on the raw materials, the manufacturers must would like to search some ways to reduce the tool costs.But because of gears high hardness after heat t...
