直径φ5毫米以下的小孔磨削,由于砂轮直径不能做得很小,磨削比较困难,我厂没有专门的小孔磨削设备,因此小孔磨削问题,已成为模具生产中的薄弱环节,针对这一难题,我们在线切割机床上,安装一个回转工作台,利用线切割机的高频电源,冷却液及坐标工作台,可以磨削φ0.3毫米以上的小孔,并可以通过调整回转工作台的倾斜度,获得适当的刃口锥度,从而解决了小孔模具磨削的困难问题,由于线切割机坐标精度甚高,且容易控制, Diameter of φ5 mm below the hole grinding, the grinding wheel diameter can not be made very small, grinding more difficult, I plant no special hole grinding equipment, the hole grinding problem, has become a weak link in the production of mold , In response to this problem, we are on-line cutting machine, the installation of a rotary table, the use of high-frequency wire cutting machine power, coolant and coordinate table, you can grind φ0.3 mm above the hole, and can be adjusted Rotary table tilt, access to the appropriate edge taper, which solved the hole grinding difficult problems, because of the high precision wire cutting machine coordinates, and easy to control,
