Casting coupling

The production process of parts is long and the process is complex, especially the hardness of ratchet tooth surface is hrc54-62, the depth of effective hardening layer is more than 3.6mm, the surface roughness is Ra0.8, the concentricity of inner hole and outer circle is 0.01mm, and the precision is high.

The products are processed by welding after circle, which requires high welding requirements. All ut flaw detection is required after welding, and the welding seam is grade 2. The roughness should be less than 0.8 and the precision should be less than 0.05mm
