Description

200*245 St52 E355 Honed Steel Tube with Thread Machined for Hydraulic Cylinder

1. Description: Honing is a kind of machining technology. Through honing head, the inner hole of cold drawn pipe is processed by reciprocating high-speed grinding technology, so that the inner hole can meet the requirements of tolerance size and surface roughness that we need.
Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder.
