When machining the synchronizer hardness between HRC58-HRC62, traditional cutting inserts such as carbide inserts with bad wear-resistance; ceramic

inserts are brittle and easy to chip; requiring frequent tool change, which results in a surface finish of Ra0.8 and a high Dimensional accuracy is difficult to 

guarantee. PCBN cutting tools is the best tools for machining synchronizers at present and their tool life and cutting efficiency are greatly improved.

Synchronizers are available in the form of atmospheric, inertial and self-energizing. At present, most of the synchronous transmissions use inertial synchronizers. 

The function of the synchronizer is to quickly synchronize the clutch sleeve with the ring gear ready to enter engagement and prevent engagement prior to 

synchronization.

For example, using our VNGA1604 tipped cutting tool to turning 20CrMnTi synchronizer gear sleeves, the tool life per cutting edge can be increased by 4 times 

compared with ceramic tools. LINKUT can provide you with professional synchronizer parts machining solutions, such as the clutch of synchronizer and ring gear 

machining.
