Combined Firmware of Deep Channels of Variable Cross-Section

Abstract

Variants of manufacturing deep channels of different cross-sections in typical details of modern equipment are considered. Most of the methods were created with the participation of the authors of the article and are protected by Russian patents. The results of the research are implemented in production at enterprises of various branches of mechanical engineering. Information is given about the original methods of piercing deep holes with a depth-to-diameter ratio of more than 25:1 by using combined processes with the imposition of high-frequency vibrations and the possibility of obtaining holes of variable cross-section in pressed ceramic and metal workpieces. The production of mating surfaces from small cross-section channels and narrow grooves is considered,which allowed us to offer an original technological process for the erosive chemical production of precision parts. This technology has been used in the manufacture of parts whose traditional processing methods are poorly understood or not feasible.In particular, a new application of combined firmware for obtaining deep holes of small cross-section in metal workpieces obtained by pressing is shown.Typical parts containing deep channels are given, the combined processing of which is the most technologically advanced and allows for a high economic effect.
