Justification of Damping Cutter Design for Making Parts for High-Pressure Drilling Unit Cylinders

The research data on the technology of manufacturing adjoining parts of valves meant to create required sealing of high-pressure drilling unit cylinders are reported in the article. The serviceability of the new design tools made of superhard composite 10 in cutting out adjoining parts from steel and plastic and in efficient shock absorption of vibrations during cutting-out has been proved. The achieved process result ensures enhanced quality of manufacturing and running efficiency of pneumatic drilling machines.
