Study of technical and economic performance indicators of restored MNP

The article presents the results of the study of technical and economic performance indicators of restored MNP in the processing of steels. As an assessment of the performance of the cutting edge of the plate, two evaluation criteria were taken: the rate of loss of the value of the face Km in € / cm3 and the cost of removing 1 m3 of chips S (1m3) in € during finishing and rough turning. The technique of obtaining the maximum performance of the process at the minimum cost of recovered plates is developed. Comparative tests of purchased and restored products in experimental and industrial conditions were carried out. As a result of the conducted experimental researches it is established that at final turning loss of cost of a face of a plate Km is 3-4 times lower at the restored plates , than at purchased. When working on rough modes restored plates criterion Km in 2-2. 5 times less.
