Honing tube factory price

 Honing fix pipe surface defects before honing tube machined surface will have a lot of pitting, which is an important factor affecting the quality of honing tube, after honing in order to obtain good quality hydraulic pipes, we need to These pits for repair. So, fix hydraulic pipe surface defects, what does? 1. Increase the amount of deformation increases cold drawn cold drawing deformation passes, increase the total amount of deformation may lead to lower pitting depth, reducing the honing grinding allowance purposes. 2. Preferred hot-rolled tube blanks drawn tube pitting defects are caused by hot-rolled tubes, so the extent of corrosion by selecting a small, uniform thickness of hot-rolled tubes can reduce pitting defects and improve the cylinder timber rate. 3. Hot-rolled tube defects in the hole to clean. Product quality is a prerequisite, and only good quality, and customer service is fundamental, therefore, hydraulic tube defects surface perfect repair, is our biggest commitment to our customers several advantages tube honing an improved surface roughness , roughness can basically reach Ra≤0.08μm. 2, the amendment roundness, ovality can ≤0.01mm. 3, to improve the surface hardness, so that by eliminating deformation, hardness HV≥4 ° 4, after processing residual stress layer, improve the fatigue strength by 30%. 5, to improve with the quality and reduce wear and extend the life of parts, but the parts but lower processing costs. Honing tube Rolling principle: it is a kind of pressure finishing, is characterized by the use of metal in the cold plastic normal condition, the use of rolling tool to exert pressure on the surface of the workpiece surface metal plastic flow, fill to the original residual low-lying valleys, rather reach the surface roughness values ??decrease. Because the surface is rolled metal plastic deformation, so cold hardening and grain tapering surface tissue, forming a dense fibrous, and the formation of residual stress layer, hardness and strength increased, thereby improving the wear resistance of the workpiece surface, corrosion and with nature. Rolling is a non-cutting plastic working method.
