电力机械加工法的本质乃是用单相、三相电热的作用,使用不大的机械压力来剥掉被加工钢球表面金属.钢球在一块固定不动的锉板上与另一块被电动机带动旋转的彼此绝缘的锉板之间辗磨,经过锉板一般频率10—25V压力的交流电,这时在钢球和锉板的接触点上,由于存在一定程度的压力,便产生相当大的电流密度,由于钢球与锉板是相对移动,便在工件与锉板的表面上产生大量的电弧,可使钢球表面软化至经过快速旋转锉板能把软化的金属微粒随着离心力的方向抛出锉板之外.
The essence of electric machining method is the use of single-phase, three-phase electric heating effect, using a small mechanical pressure to strip the surface of the metal ball is processed. Ball in a stationary file with another piece of the motor Driven between the rotation of the insulation between the rasp mill, after the rasp frequency of the general frequency of 10-25V AC, then the ball and the file at the point of contact, due to the existence of a certain degree of pressure, they have a considerable Current density, due to the relative movement of the ball and the rasp, generates a large amount of electric arc on the surface of the workpiece and the rasp, which softens the surface of the ball to a rapid rotation. The rasp can soften the metal particles in the direction of centrifugal force Throw out the rasp outside.
