After a series of orders for gears and gear shafts, there is an order for couplings that appears in our view.Couplings are mechanical parts which is used to firmly connect the drive shaft and the driven shaft in different mechanisms to rotate together and transmit movement and torque. Sometimes it is also used to connect shafts to other parts (such as gears, pulley, etc.). The processing technology of the coupling is more, at present, its current processing state is milling the inner surface.。
