针对我国水泥压力管接口加工一次成型的技术难题,国家建材局人工晶体研究所研制的“新型φ1000毫米水泥压力管加工用金刚石组合刀具”于1990年5月19日在江苏徐州通过了有关方面的技术鉴定。长期以来,我国水泥压力管接口处的承口、坡口加工一次成型始终是个难题。传统加工方法是将浇铸成型的水泥管毛坯卡住,先磨削承口部分,然后换刀,再加工坡口,产品标准化程度低、互换性差,管子接通后,易渗水、漏水。并且在加工时操作麻烦,费工费时,效率低,加工成本高。这 In view of the technical problems of forming once the cement pressure pipe connector in our country, the “new type of diamond combination cutter with φ1000 mm cement pressure pipe” developed by the National Institute of Building Materials IOL passed on May 19, 1990 in Xuzhou, Jiangsu Province Technical appraisal For a long time, China’s cement pressure pipe interface at the mouth, beveling a molding process is always a problem. The traditional processing method is to cast molded cement pipe blank stuck, the first part of the grinding socket, and then change the knife, and then processing bevel, product standardization is low, poor interchangeability, the pipe is connected, easy seepage, leaking. And the operation of the trouble in the processing, work time-consuming, low efficiency, high processing costs. This
