在电火花小孔磨削加工中,很难找到一种确切的测量方法。因为不论立式结构或卧式结构的电火花小孔内圆磨削机床,总要用一根铜丝作为电极穿在小孔中,然后将铜丝拉直拉紧方可加工。经过一段加工我们要对小孔进行测量,检查一下小孔加工还有多少余量。对大一点的孔可以直接用卡尺或卡钳检测,但对小孔,如φ3毫米以下的孔就无法用上述方法了。只好用开槽 EDM hole grinding process, it is difficult to find an exact measurement method. Because of vertical structure or horizontal structure EDM hole grinding machine, always use a copper wire as the electrode to wear in the hole, and then pull the copper wire straightened to be machined. After a period of processing we need to measure the hole, check how much hole processing allowance. The larger hole can be directly measured with calipers or calipers, but small holes, such as φ3 mm below the hole can not use the above method. Had to use slotting
