针对D3550立式电解机床的不足,我们提出了用数显技术改造电解机床数显控制器的方案。用阴极位移量的直接测量法代替原设备中的间接测量法,从而消除了传动间隙对加工精度的影响;采用抗干扰性能好的CMOS元件代替PMOS元件;用双列直插封 In response to the lack of D3550 vertical electrolytic machine, we proposed the digital display technology to transform the electrolytic machine digital controller program. The direct measurement of cathode displacement instead of the indirect measurement of the original equipment, thus eliminating the transmission gap on the machining accuracy; using anti-jamming CMOS components instead of PMOS components;
