Investigation into Method of Electric Hot Drilling to Minipore

摘要

Based on the electric hot method has been applied to turning effectively, this paper analyzes electrical properties of the electric hot cutting micro area, according to contact resistance theory the electrical conduction model of cutting micro area is established, electric hot method applied to minipore drilling of hard-to-cut materials is discussed, it develops a set of electric hot drilling device which is simple and flexible. Under the conditions of the same drilling parameters, electric hot drilling tests and ordinary drilling hole experiment are researched contrastively. Test results show that axial force and torque of electric hot drilling experiment are reduced obviously than that of ordinary drilling holes experiment. Electric heating method applied in drilling process is very effective.
