(1) It can process parts that are difficult to be processed by metal cutting methods, and is not affected by the hardness of the material and the heat treatment of the material.
(2) Since the tool electrode is not in direct contact with the workpiece electrode, and there is no mechanical cutting force, it is not necessary to consider its force characteristics when making the tool electrode. The tool electrode can be made very fine, and can perform fine machining and complex surface machining.
(3) Machining is to erode metal materials by pulse discharge, and the parameters of the pulse power supply can be adjusted at any time, so in the same case, roughing, semi-finishing, finishing, and super-finishing can be switched only by adjusting the electrical parameters. processing.
Due to the above characteristics of radial drilling machines, this technology has been widely used in aerospace, aviation, machinery (especially mold manufacturing), instrumentation, light industry and scientific research.
Although machining with a radial drilling machine has the above advantages, it also has disadvantages.
