METHOD FOR SELECTING PARTS RECOVERY TECHNOLOGY

Abstract

METHOD FOR SELECTING PARTS RECOVERY TECHNOLOGY

             Remanufacturing of parts allows the use of their material, shape and residual durability, which reduces the need for spare parts, labor, energy and materials, and also helps to preserve the environment. Research has established that 85% of machine parts become inoperative when surfaces wear no more than 0.2-0.3 mm, and the cost of their restoration is 50-60% of the price of a new part. Worn surfaces can be repaired, as a rule, in several ways. Depending on the amount of wear, the material of the part and heat treatment, a method is proposed for choosing a rational technology for restoring a worn surface, depending on the technological capabilities of production, operating conditions, the cost of restoration, the dependence of the cost of restoration on the durability of work. These factors are assessed sequentially according to technological, resource and economic criteria. The final decision regarding the choice of recovery technology is made at a specific production facility using its technical and financial capabilities.
