    • In order to perform turning operations of the kind that has heretofore been performed by diamond-shaped inserts, using a triangular insert with multiple alternately usable cutting edges, of which all three corners are usable as cutting edges, without lowering the positional accuracy of the cutting edge during cutting, according to the present invention, at least one V-shaped recess 5 and a plurality of V-shaped protrusions 6 are formed on each side of an insert 1 which is basically equilateral triangular in shape. The recess 5 and protrusions 6 are brought into engagement with a V-shaped protrusion and V-shaped recesses 18 formed on a side wall 12b of a seating groove formed in a holder 11. In this state, the insert 1 is pressed against a bottom seating face and the side wall of the seating groove with a clamp means to stably restrain the insert. This prevents shifting of the cutting edge during cutting even if the direction of the cutting force changes.
    • 为了执行迄今为止由金刚石刀片进行的那种的车削操作,使用具有多个可交替使用的切削刃的三角形刀片,其中所有三个角都可用作切削刃,而不降低切削的位置精度 根据本发明,在基本上是等边三角形的插入件1的每一侧上形成至少一个V形凹部5和多个V形突起6。 凹部5和突起6与形成在保持器11中的形成在座槽的侧壁12b上的V形突起和V形凹部18接合。 在这种状态下,插入件1用夹紧装置压靠底座和底座槽的侧壁,以稳定地限制插入件。 这样即使切削力的方向发生变化,也能够防止切削时的切削刃的移位。

    • In order to perform turning operations of the kind that has heretofore been performed by diamond-shaped inserts, an insert which is basically equilateral triangular in shape with multiple alternately usable cutting edges, of which all three corners are usable as cutting edges, without decreasing the positional accuracy of the cutting edge during cutting. At least one recess and a plurality of protrusions are formed on each side of the insert. The recess and protrusions formed on the insert are brought into engagement with a protrusion and recesses formed on a side wall of a seating groove formed in a holder.

This prevents shifting of the cutting edge during cutting even if the direction of the cutting force changes.
