单角铣刀磨孔生产中,往往将压板压紧在端面齿上,由于齿面接触点少,工件受力不匀,极易发生工件走动,甚至工件飞出,造成不必要的安全事故。我厂工具车间内圆磨床工人,在加工生产的实践中,改为采用如图所示的安全圈,工件受力均匀,也很安全。 Single-angle milling cutter mill production, the pressure plate is often pressed on the face teeth, the tooth surface contact points less uneven stress on the workpiece, the workpiece easily move around, and even the workpiece fly out, resulting in unnecessary safety incidents. I plant tool shop internal grinder workers, in the production of the practice, instead of using the safety ring as shown in the figure, the work force evenly, but also very safe.
