6A 463仿型电火花腐蚀刻字机的工作原理(图1),经整流和调压后的直流电一端与刻字机内感应线圈5联接,另一端与被加工零件联接。工作时装夹在主轴6端部的钨丝(或钼丝)与工件接触。电路接通,感应圈产生磁场,将主轴吸上,钨丝脱离工件,电路断开滋场消失。主轴在弹簧8的作用下往下移动。钨丝又与工件接触形成通路。如此循环不断的接通与
6A 463 imitation EDM etching plotter working principle (Figure 1), after rectification and regulation of one end of the DC and the scoring machine induction coil 5 connected to the other end of the workpiece is connected. The tungsten wire (or molybdenum wire), which is clipped to the end of the spindle 6 in working fashion, is in contact with the workpiece. The circuit is connected, the induction coil generates a magnetic field, sucks the spindle, the tungsten wire breaks away from the workpiece, the circuit is disconnected and the zenith disappears. The spindle moves downwards under the action of the spring 8. Tungsten wire and the workpiece contact with the formation of access. So constantly connected with the cycle
