LST CNC wire cutting

In order to manufacture high-quality sprag clutch, a processing technology of sprags based on the WEDM-LS( low speed wire cut electrical discharge machining) was proposed. Adopting orthogonal method to exper- iment on wire cutting electrical parameters and analysizing surfaces of wire cutting sample with scanning electron mi- croscope. The result shows that the sequence of factors effecting the surface roughness is pulse width, stop time, the servo ratio and the initial voltage, and there is a loose structure on the metamorphic layer, which contains Cu and Zn and with the thickness of about 15 to 20 um.

QC department

In order to ensure the quality of the finished products, a very strict QC management system has been adopted. We inspect each product 4 times by different worker to ensure that all outbound products meet the drawing requirements.
