为了适应工农业发展对锻模加工的需要,北京机床研究所、国营昆仑机械厂、天津第六机床厂联合设计并由天津第六机床厂试制的D3575中型立式电解机床,以及北京变压器厂研制的KGXS—10kA/3—20V可控硅整流装置已先后试制成功。为进一步推广电解加工新工艺,第一机械工业部委托陕西省机械工业局、陕西省第五机械工业局、天津市第一机械工业局联合主持这两项产品的国家鉴定。
In order to meet the needs of industrial and agricultural development for forging die machining, the D3575 medium-sized vertical electrolytic machine tool jointly designed by the Beijing Machine Tool Research Institute, the state-run Kunlun Machinery Plant, and the Tianjin No. 6 Machine Tool Plant and developed by the Tianjin No. 6 Machine Tool Plant and the Beijing Transformer Plant The KGXS-10kA/3-20V silicon controlled rectifier devices have been successfully tested. To further promote the new electrolytic processing technology, the First Machinery Industry Ministry commissioned the Shaanxi Provincial Machinery Industry Bureau, the Shaanxi Province Fifth Machinery Industry Bureau, and the Tianjin First Machinery Industry Bureau to jointly preside over the two countries’ product appraisals.
