小经验加工钨基合金这种导电性能较差的材料时，总是断丝。于是在加工前更换冷却液，洗刷导轮与导电杆，以保证机床清洁。由于它导电性能差，进给电流十分关键，原来加工电流为１．５Ａ（最大），以为这样会提高效率，结果事与愿违。当进给速度大于腐蚀速度极易断丝。应使... Small experience processing tungsten-based alloys, poor conductivity of the material, always broken wire. So in the process of replacement of coolant, scrub guide wheel and the conductive rod to ensure that the machine clean. Due to its poor conductivity, the feed current is critical, the original processing current of 1.5A (maximum), in the interest of this will increase efficiency, the result is contrary to expectations. When the feed rate is greater than the corrosion rate can easily broken wire. Should make ...
