仪表零件上的高精度的孔,除采用坐标镗床和轻型精密镗床加工外,还可采用小型组合机床进行加工。用小型组合机床可在同一工艺基准上进行自动循环加工,由于同时采用多刀加工,因此提高了加工精度和工序集中程度,从而缩短总的加工循环时间,提高劳动生产率1—3倍,并把大量的通用金属切削机床解放出来,以及提高了整个自动化和文明生产水平。
High-precision instrument hole on the parts, in addition to the use of coordinate boring machine and light precision boring machine processing, but also the use of small combined machine tools for processing. With a small combined machine tool in the same process on the basis of automatic cycle processing, due to the use of multi-knife processing, thus improving the machining accuracy and concentration of processes to shorten the total processing cycle time, improve labor productivity 1-3 times, and the The liberation of a large number of general-purpose metal cutting machines, as well as raising the overall level of automation and civilized production.
