Study of some aspects of refining process physics of large-sized details precision surfaces

Abstract

The paper presents experimental studies on physical and chemical processes that occur as a result of refining by ‘GOI’ paste (description in CIS countries, it states for State Optical Institute) largesized precision details made from non-ferrous metals.Number of hypotheses expressed by number of scientists is compared.Their essence has been revealed and a hypothesis has been adopted and confirmed by Corresponding profilograms and photographs. It is most relevant to process of refining by ‘GOI’ paste of precision contacting inserts made from nonferrous metals. This is very important for agricultural engineering.
