Supply OEM/ODM CNC Part 3D Printer Kits Polished Hardened Chrome Plated Motor Shaft Gcr15 S45c Induction Hardness Precision Motion Bearing Transmission Guide Linea Shaft
In precision optical shafts, there are usually requirements for surface hardness. The purpose of external surface hardness is to improve wear resistance. For metal materials, the harder the hardness, the more wear-resistant it is. However, the harder the core, the lower the toughness, and the lower the load-bearing and impact resistance. Therefore, for important shaft requirements: external hardness and internal toughness.
