The main processing spare parts of the CVT transmission with CBN cutting inserts is as follows:

1) Active wheel shaft

2) Driven wheel shaft

3) Active pulley

4) Driven pulley

Such as our BNT4 coated tipped PCBN insert for the driven wheel shaft of the CVT transmission machining, compared with other famous foreign CBN grade, the tool life

 increase at least 10%.

CVT (Continuously Variable Transmission), CVT usually refers to a car transmission, also known as a continuously variable transmission, which is what we often call a super

 gearbox. As the name implies, there is no clear specific gear, and the operation is similar as the automatic transmission, but the change of the speed ratio is different from the 

shifting process of the automatic transmission, but continuous, so the power transmission continues and smooth.
