五月下旬,第四技术交流站在一一八厂召开了线切割技术交流会。会上,一一八厂介绍了“间隙自动补偿线路”。其特点是线路简单、元件少、体积小,是在输入时进行补偿运算,故障容易发现和避免。还介绍了他们革新的短钼丝切割法:在机械上采用了小功率直流电机及惯性小的丝筒,对光洁度有所改善。一一七厂介绍了“带有锥度和间隙补偿的MOS中型数控线切割机”。其特点是集成度高,功耗小,抗干扰能力强,逻
In late May, the fourth technical exchange station convened a wire cutting technology exchange meeting at 118 plants. At the meeting, one hundred and eight plants introduced the “gap automatic compensation circuit.” Its characteristics are simple lines, fewer components, small size, is the input compensation operation, easy to find fault and avoid. They also introduced their innovative short molybdenum wire cutting method: the mechanical use of a small power DC motor and a small inertia of the wire tube, the finish has been improved. One hundred and seven factory introduced “MOS with medium taper and clearance compensation CNC cutting machine.” It is characterized by high integration, low power consumption, anti-interference ability, logic
