Description

Изобретение касаетс  размерной обрабЪт-.The invention relates to dimensional processing.

ки деталей.ki details.

Известен способ электрохимического травлени  стальных деталей в электролите, содержащем соли азотной и серной кислот.There is a method of electrochemical etching of steel parts in an electrolyte containing salts of nitric and sulfuric acids.

Предлагаемый способ отличаетс  тем, что в электролит ввод т уксуснокислый натрий а комцоненты вз ты в следующем соотЙЬшеНИИ , в г/л: сернокислый натрий 7 0-&Э,взотнокислый натрий 45-55, уксуснокислый натрий 2О-ЗО, при режиме обработки: температура электролита 20-28°С, плотность тока 60-70 A/cM cK fecib электролита 4045 м/сек.:,The proposed method is characterized in that sodium acetate is introduced into the electrolyte and the components are taken as follows, in g / l: sodium sulfate 7 0-& E, sodium acetate 45-55, sodium acetate 2O-30, during processing: electrolyte temperature 20-28 ° С, current density 60-70 A / cM cK fecib electrolyte 4045 m / s:,

Согласно изобретению, пред лож енныйспособ позвол ет получить чистоту поверхностиAccording to the invention, the proposed method allows to obtain a clean surface.
