Modern methods of tool finishing
Finishing allows you to improve the surface quality of machine parts and achieve the specified accuracy, its results finally determine the characteristics of the product as a whole. The choice of finishing methods is determined by the physicochemical properties of the alloy, the configuration of the parts, the purpose and future conditions of its operation. In some cases, it may be necessary to carry out a whole complex of finishing metalworking operations.
The Ryazan Polytechnic Institute has developed a prototype equipment capable of using vortex cavitation for finishing parts. At the initiative of ZIV LLC (Ryazan), together with PTM LLC (Moscow) and the Ryazan Polytechnic Institute, it was decided to apply cavitation technologies forthe finishing processing of shaping tools (for the production of building fasteners). A die and a set of production thread rolling dies were taken as experimental samples.
