我厂的数控线切割机床从72年开始筹备制造,73年总装调试完工,到现在运行了二年半左右的时间。共切出大小模具100多付,样板300多件,并为兄弟厂加工十几付模具。现在的切割速度可达60毫米~2/分,最大切割厚度为65毫米,光洁度▽6。虽然目前还不能满足生产上的需要,但通过生产实践也解决了一部分问题,现将实践中的体会提供同志们参考。第一台数控线切割机虽然制造成功了,但是还不够完善,主要是生产效率低,每分钟只有十几平方毫米,最大切割厚度只在20毫米以下,加工表面上出现条纹,丢数、
I plant NC wire cutting machine tools from 72 to prepare for manufacturing, assembly and commissioning completed 73 years, and now run for about two and a half years. A total of cut the size of more than 100 molds, more than 300 samples, and processing more than a dozen mold factory brothers. Now the cutting speed of up to 60 mm ~ 2 / min, the maximum cutting thickness of 65 mm, finish ▽ 6. Although the current production can not meet the needs, but also solved some of the problems through the practice of production, now the practice of comrades to provide reference. Although the first CNC wire cutting machine was successfully manufactured, it was still not perfect. The main problems were low productivity, only a dozen square millimeters per minute, the maximum cutting thickness was only less than 20 millimeters, stripes on the machined surface,
