在电解加工工艺中,有两种电解加工方法。一种是气水混合法,即常说的混气加工;另一种是不混气加工。目前我厂采用的是不混气加工工艺。采用不混气加工,对阴极设计、机床精度、电源保护装置以及电解液的精过滤都要求较高。目前,煤炭部所属厂矿所用的电解机床,大都是各单位自己制造或改装的设备,因而各项性能都较差。尤其是机床的稳定性达不到要求,以致在加工零件或锻模时很容易发生问题。其原因除设备因素之外,影响电解加工成败的更主要的因素,是流场设计和电解液的过滤。我们根据几年来的实践,感到过滤问题是一个很重要的环节。由于电解液 In the electrolytic processing technology, there are two kinds of electrolytic processing methods. One is the gas and water mixing method, which is often said mixed gas processing; the other is not mixed gas processing. At present, I plant is not mixed gas processing technology. The use of non-gas processing, the cathode design, machine accuracy, power protection devices and electrolyte filtration requirements are high. At present, most of the electrolytic machine tools used by factories and mines owned by the Ministry of Coal Industry are all equipment manufactured or modified by the units themselves, and therefore all the performance is poor. In particular, the stability of the machine can not meet the requirements, so when processing parts or forging die is prone to problems. The reason other than equipment factors, the more important factor affecting the success or failure of electrolytic processing is the flow field design and electrolyte filtration. Based on years of practice, we feel that the issue of filtration is a very important link. Due to the electrolyte
