New production operations for working parts of difficult-to-work materials (a subject collection)

The technological organizations of the chemical and petroleum machinery industry have devoted much attention to the problems of increasing labor productivity and economy in material costs in the working parts of difficult-to-work materials. The collaboration of organizations has made it possible to broaden the area and increase the effectiveness of the use of tools of superhard materials. Highly productive machining methods, such as the method of plasma machining of parts, have been introduced into the industry. The electrocontact method of machining blanks of difficult-to-work alloys, and the magnetic hardening method have also been introduced. The purpose of this published collection is to discuss new production operations and tools for the working of parts of difficult-to-work materials for their wide use in the industry.
