Repair of screws
1. The twisted screw should be manufactured based on the actual inner diameter of the barrel, and the deviation of the outer diameter of the new screw should be given according to the normal clearance with the barrel.
2. After the surface of the thread with reduced diameter of the worn screw is treated, high-temperature spraying of wear-resistant alloy (this wear-resistant alloy is composed of materials such as C, Cr, Vi, Co, W, and B) is carried out, followed by grinding of the tooth edges, trimming, polishing of the tooth bottom, and matching with the material cylinder. The service life can reach over 98% of the new value.
