Marksa, Novosibirsk, 630073, Russian Federation Abstract The paper examines the need to create and the effectiveness of using hybrid technological equipment based on a centerless grinding machine for the production of pin-type parts. The object under consideration is the rod and various pins of the design of the responsible mechanism for finetuning the crystals of a double-crystal monochromator. The purpose of the work is to evaluate how justified and productive the use of hybrid technological equipment created on the basis of a centerless grinding machine for the manufacture of pin-type parts is. The theoretical section examines a typical technological process for manufacturing a pin, concluding that the main productivity losses arise from actions on workpieces that are not associated with material removal, and reducing the time between processing stages can be achieved by combining equipment for mechanical and heat treatment processes. Based on the analysis of methods of surface treatment of metals presented in the results and discussion section, the most rational method for hardening pins was selected. This method is high-energy heating with high-frequency currents (HEH HFC). As a result of the study, it was concluded that it is necessary to modernize the equipment, since this helps to increase its productivity. Keywords Centerless grinding, high-energy heating with high-frequency currents (HEH HFC), hybrid equipment.
