重庆机床厂从西德进口的HSF33A大螺旋角滚刀铲磨床,用于铲磨滚刀侧面的“特波牌”(TEMPO)磨头已经损坏,向外商订货不但价昂,而且长期无货供应。我所于1977年与重庆机床厂一起研究,研制成第一套配用于该磨床的空气静压透平磨头,转速30,000转/分,效果良好。为了扩大应用,又研制了两种适于粗、精磨的磨头(分别为30000转/分、50000转/分),1979年1月装机试验,也取得良好的效果。经试磨鉴定,能满足使用要求,且某些性能还优于“特波牌”滚珠轴承皮带
Chongqing Machine Tool Works imported from West Germany HSF33A large helix hob cutter grinder, used to shovel hob side of the “Tebo card” (TEMPO) grinding head has been damaged, to foreign orders not only expensive, and the long-term stock . In 1977, I worked with Chongqing Machine Tool Works to develop the first set of air-driven static pressure turbine grinding heads for this grinder at 30,000 rpm with good results. In order to expand the application, but also developed two kinds of grinding head for coarse and fine grinding (respectively 30,000 r / min, 50000 r / min), installed test in January 1979, also achieved good results. After the trial identified, to meet the requirements, and some of the performance is also better than the “special wave card” ball bearing belt
