NC磨削内圆时,法向磨削力通常用检测主轴轴承压力的方法测得,切向磨削力则用检测主轴电动机功率再进行转换的方法获得。但这些方法都不能同时测得两种磨削力,从而限制了控制技术的应用。日本SEIKO精机株式会社,应用磁性轴承控制的传感技术,开发了能同时精确测量法向和切向磨削力 NC grinding inner circle, the normal grinding force is usually measured by the spindle bearing pressure measurement method, the tangential grinding force is detected by the spindle motor power and then converted to obtain. However, neither of these methods can measure both grinding forces at the same time, thus limiting the application of control technology. Japan SEIKO Seiki Co., Ltd., the use of magnetic bearing-controlled sensing technology, has developed a precise measurement of both normal and tangential grinding force
