在加工箱体零件时,大部分工作量是加工内孔,内孔的测量常采用内径千分表或精密的游标卡尺。加工内孔时,一般先试切削一刀,测量其尺寸是否到达公差范围内,这时孔的切深很浅,仅2～5mm左右,采用内径千分表测量,表的触头无法塞入放平。有时还会遇到双层内孔的加工,对内层孔初次试切的测量,不仅内径表无法放,连游标卡尺也无法伸入。另外,组合机床上镗刀的调整大多采用人工,由于刀具排
In the processing of parts of the box, most of the workload is processing the hole, the hole is often measured using the internal diameter micrometer or precision vernier caliper. Processing hole, the general first try cutting knife, measuring the size of it is within the tolerance range, then the hole depth of cut is very shallow, only 2 ~ 5mm or so, using the inner diameter dial gauge, the table can not be inserted into the contact level. Sometimes encounter double-hole processing, the first hole cutting the inner hole measurement, not only can not put the inner diameter of the table, even the Vernier caliper can not be reached. In addition, the combination of boring machine tool adjustment mostly artificial, due to the row of tools
