Internal skiving and roller burnishing steel tube Introduction
Internal skiving and roller burnishing steel tube Roll the metal surface with rollers, flattening the surface of the surface, and lift the concave part to smooth the surface of the mirror. Unlike cutting, it is a plastic processing. By rolling processing of workpiece surface roughness moment can not only achieve Ry0.1 0.8 mu m, and its wear resistance was improved after machining surface hardening of fatigue strength at the same time also increased by 30% and possesses the advantages of cutting couldn't get in. Because can simply and in parts of ultra precision machining at low cost, increasingly, led by the auto industry, precision machinery, chemical, electrical appliances and other industries widely used, has played a great advantage.
Internal skiving and roller burnishing steel tube technical parameters
Production process
Raw material – annealing for material of 45#, 27SiMn, 25Mn – Acid cleaning – parkerizing & Saponifying – cold drawn – leveling – saw off bad section – stress relieving – leveling – honing or skiving – inspection – oiled plated - packing
Quality control
1. We only buy raw material from famous tube factory, and Checking raw material quality before production.
2. We check the tube ID tolerance, OD tolerance and surface after cold drawn one by one.
3. We inspect the honed tube inside tolerance and surface again one by one after honing or skiving.
