秦川机床厂的QC-004叶片油泵转子磨床的结构与液压、电气系统比较完善,加工的转子质量较好,工效也较高。该机需配用外径φ350毫米、厚3毫米的薄型砂轮,由于规格特殊,货源短缺,使转子槽磨削这道关键工序经常遇到很大困难。为了适应1978年跃进形势的要求,我厂工人、干部、技术人员密切协作,对一台转子磨床进行了改装,使几年来已用过的废旧砂轮全部获得回用,解决了当前生产上的一大难题。具体办法是:1.加工一块厚11毫米的夹具体垫板(见图1),使夹具体向砂轮方向前移20毫米,
Qinchuan Machine Tool Factory QC-004 blade pump rotor grinder structure and hydraulic, electrical system is relatively complete, the processing of the rotor better quality, high efficiency. This machine should be equipped with a φ350 mm outer diameter and a thickness of 3 mm thin grinding wheel. Due to the special specifications and short supply, it is often difficult to grind the rotor slot in this key process. In order to meet the requirements of the leap forward in 1978, our factory workers, cadres and technicians worked closely to modify a rotor grinder, so that all the used grinding wheels that have been used in the past few years have been reused to solve the current production Big problem The specific approach is: 1. Processing a thick 11 mm clamp plate (see Figure 1), the clamp body to the wheel forward 20 mm,
