近年来,机械工业、电机电器、仪表工业、轻工业、国防工业及其它行业对模具的需求量增加,精度要求提高,六十至七十年代生产的电加工机床很难满足加工要求。为适应我国技术发展的需要,对老的电加工机床技术改造很有必要。我所1984年初对营口电火花机床厂1968年出厂的一台D6125型电火花加工机床装上光栅数显,三年来工作正常隐定可靠,加工了许多精度要求高的零件。机床改造前,位置精度要求0.10mm的型腔很难保证,虽
In recent years, the mechanical industry, electrical appliances, instrumentation industry, light industry, national defense industry and other industries to increase the demand for molds, precision requirements increase in the sixties and seventies production of electric machining machine is difficult to meet processing requirements. In order to meet the needs of technological development in our country, it is necessary for the technological transformation of the old electric processing machine tools. At the beginning of 1984, I installed a D6125 EDM machine manufactured by Yingkou EDM Machine Tool Factory in 1968 to install a grating digital display, and the work in the past three years was subtle and reliable and many parts with high precision requirements were processed. Before the transformation of machine tools, the position accuracy of 0.10mm cavity is difficult to guarantee, though
