Honing pipe before processing the surface will have a lot of hemp point, which is an important factor affecting the quality of honing pipe, to get the quality of the hydraulic oil tubes after quilting, it is necessary to repair these points.
So, what are the methods for repairing the surface defects of honing tubes?
- Increase the amount of cold-drawn deformation
Increasing the number of cold-drawn deformation and increasing the total deformation can achieve the purpose of reducing the depth of the hemp point and reducing the honing grinding allowance.
- Preferred hot-rolled tube blanks
Cold-drawn pipe defects are caused by hot-rolled pipe, so, through the selection of small corrosion degree, uniform wall thickness of the hot-rolled pipe, can reduce the defects of the hemp, improve the yield of the cylinder.
- Hot-rolled pipe hole defect cleaning
g is also relatively low, if the diameter is greater than 50mm, it is best to use mechanical processing method cutting, to ensure that the tube cutting surface of the flat, can not have burrs, oxide, slag and other defects exist.
Besides honing tube, Datong Hydraulic also produce and supply induction hardened chrome plated cylinder rods.hydraulic cylinder barrel,hollow chrome bar
