要在电火花刻模机床上将6mm×6mm的高速钢方棒切成需要的长度。在机床的拖板上装有小动力头以便带动电极旋转。电极由直径为100mm、原为1.2mm的铜圆片组成,两片的间距等于所需的工件长度,片的转动速度约为125r/min。
In the EDM machine will be 6mm × 6mm high-speed steel square bar cut into the required length. A small power head is mounted on the carriage of the machine to drive the electrode to rotate. The electrode consists of a copper disc with a diameter of 100 mm and a thickness of 1.2 mm. The distance between the two pieces is equal to the required length of the workpiece. The rotation speed of the sheet is about 125 r / min.
