为了提高磨床的磨削效率,减少空行程的时间,使砂轮开始时作快速进给运动,而在触及工件时转为磨削送给运动,为此需要检测出砂轮和工件的接触。近年来国内外有关工厂根据采用不同的检测方法,研制了各种控制室程装置。 一、用砂轮电机输入用率或功率因数测定法 无锡机床电器厂生产
In order to improve the grinding efficiency of the grinding machine and reduce the empty travel time, make the grinding wheel begin to make the rapid feed movement, and turn the grinding feed motion when touching the workpiece, so it needs to detect the contact of the grinding wheel and the workpiece. In recent years, factories at home and abroad based on the use of different detection methods, developed a variety of control room device. First, with the wheel motor input or power factor measurement Wuxi Machine Tool Factory production
