两年来,我厂仅在阀门车间备料班对14种总数达1890件零件进行仿形精密切割。以精切代替机械加工,节省工时总数约2602小时,如果以我厂加工工时费一小时4元计算,共节约工时费10400多元;初步掌握了仿形精密切割工艺.为生产、质量管理的需要初步拟订了切割质量和尺寸精度标准。经实践证明,液化石油气精切的好处是:1.某些机械加工零件可以做到用精切来代替,零件的部分或全部外形不需机加工。2.切割速度快,提高零件加工生产效率,缩短生产周期,降低生产成本。
Over the past two years, I plant only in the valve shop preparation classes on the 14 kinds of total number of 1890 parts for precision cutting precision. To cut instead of machining precision machining, saving a total of about 2,602 hours of working hours, if I plant processing fee of 4 hours an hour calculation, a total cost savings of 10400 yuan working hours; preliminary mastered the precision cutting technology for the production, quality management needs Preliminary development of cutting quality and dimensional accuracy standards. Proved by practice, LPG precision cutting benefits are: 1. Some machined parts can be replaced by fine cut, some or all parts of the shape without machining. 2. Cutting speed, improve part production efficiency, shorten the production cycle, reduce production costs.
