目前在普通机床或数控机床上进行车、镗、铣削加工时,广泛使用装可转位刀片的标准刀具。标准刀具分为两大类,一类是符合国际标准或国家标准的刀具,另一类是按企业标准制造的刀具。本文讨论车削和镗削过程中常用的装可转位刀片的标准刀具,诸如机械夹固车刀、切断刀、切槽和螺纹加工工具、可微调的镗刀以及小孔加工刀具。 Currently in general machine tools or CNC machine tools on the car, boring, milling, the widely used indexable inserts can be equipped with standard tools. Standard knives are divided into two categories, one is in line with international standards or national standards of knives, the other is based on enterprise standards of knives. This article discusses standard tools for indexable inserts commonly used in turning and boring operations such as machine-clamping tools, cutting knives, grooving and threading tools, finely adjustable boring tools, and small hole machining tools.
