Jinzhou wang machinery parts co., LTD

Finished steel pipe is also called cold rolled precision tube, is one of the types of seamless steel tube production process

Suction rebound after spring shock absorber is mainly used to suppress the shock and impact from the ground, in the process of about modification of the suspension system, the shock absorber of hard and hard spring is tie-in, the hardness of the spring is closely related to vehicle weight, so the heavier car generally adopt a hard shock absorbers. A device connected and lead the crankshaft, fight the crankshaft torsional vibration.
 

With cold drawing method and produce all kinds of cold drawn steel. Cold drawing of features are: high accuracy, good surface quality. Cold drawn mainly for the production of steel wire. Also used in the production of a diameter of 50 mm below of round steel and six Angle steel, and steel tube under 76 mm in diameter.
 

Piston rod processing requirement is high, the requirements of the surface roughness is Ra0.4 ~ 0.8 um, strict in alignment and abrasion resistance. The basic characteristics of the oil cylinder rod is slender shaft processing, the processing difficulty is big, has plagued the processing personnel.
