我厂自1985年引进日本三菱电机生产的 M75C6电加工机床及数控铣床以来,效果很好。特别是加工电视机外壳等塑料模具的成效更为显著。电视机外壳模具的加工难度较大,它的尺寸精度高,几何形状复杂,对外观的要求严格.其型腔部分用电加工成形,其尺寸在700～1000mm 左右。大型型腔的电加工与小型型腔有不同的特点。在加工襄樊电视机厂的54cm 彩电外壳模具型腔时,由于较为合理地调整了各种加工规准,适时地进行了电规准的转换和非电条件的改变,因而在满足质量要求的基础上,控制了电极的相对损耗,大大地提高了加工速度。并使加工速度、表面粗糙度、电极
I plant since 1985, Japan’s MITSUBISHI Electric M75C6 electrical processing machine tools and CNC milling machine, the effect is very good. Especially the processing of plastic TV sets and other plastic molds more significant effect. TV shell mold machining more difficult, its high dimensional accuracy, complex geometry, the appearance of the strict requirements of its part of the cavity formed by electrical processing, the size of about 700 ~ 1000mm. Large cavity electric machining and small cavity have different characteristics. In the process of processing the 54cm color TV shell mold cavity of Xiangfan TV Factory, due to more reasonable adjustment of various processing standards, timely conversion of electrical standards and non-electrical conditions, and thus meet the quality requirements of the foundation On the control of the electrode relative loss, greatly improving the processing speed. And make the processing speed, surface roughness, electrode
