The function of honing is to improve the surface finish and wear resistance of the workpiece. The most important point is wear resistance, because the surface of the honed object forms a certain angle of cross-patterns, and these patterns can retain a certain amount of oil to lubricate. Therefore, the workpieces that need to be honed are usually in the car engine cylinder block or cylinder liner, various hydraulic oil cylinders, various hydraulic valve bodies, automobile connecting rods, motorcycle cylinder blocks, etc., and similar linear motion or rotation needs to be reduced.

The honing tube is a cold-drawn precision seamless steel tube, which is a high-precision steel tube material processed by cold-drawing or hot-rolling. Since the inner and outer walls of the precision steel tube have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used to produce products for pneumatic or hydraulic components, such as cylinders or Cylinder, can be seamless pipe. The chemical composition of the quilted grinding tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
