1. Brief Introduction:

2.Manufacturing:

Steel pipe→cutting→Heat treatment (if the customer requires)→Honing inner diameter (high dimensional accuracy, high roughness)→CNC processing (outer diameter, length, thread and other shapes of the car)→Inspection →Anti-rust oil protection/plating/electrophoresis blackening and other surface treatments→Packaging

3. About CNC:

CNC milling machine is also called CNC (Computer Numerical Control) ,meaning a milling machine controlled by digital signals from an electronic meter, which is an automatic processing equipment developed on the basis of general milling machines.

4. Package:

The CNC machining parts are packed in the plastic bag, wooden pallet, paper fiber,plastic bag or according to the request.
