In order to meet the needs of production, the company has purchased a CNC skiving and rollers burnishing machine. The equipment is mainly used for the fine boring and rolling processing of the inner hole surface of the cylinder body. The processing materials can include 20 ᦇ, 45 ᦇ, 25MN, 27SiMn, etc. Machining accuracy: the machining accuracy of inner diameter can reach grade I T7-T8, and the surface roughness can reach ra0.05-0.1. Processing size: inner diameter 50-250mm, outer diameter 60-300, processing length 500-3000mm.
