Product Introduction
By the rotary motion of workpiece and reciprocating movement of cutting tool, most material allowance is removed to achieve target shape, dimension and precision. It can be used as pre-process before heat treatment.
1: Chipbreaker Geometry & Features
Chipbreaker | | | Application | Features |
|---|---|---|---|---|
BS |  |  | Profiling machining (Negative insert) | Recommended for profiling. 3-stage chip breaking points ensure stable chip control during profiling. Sharp cutting edge reduces cutting force and delivers superior surface finish. Inclined edge & wavy flank design enables smooth chip evacuation under variable depth of cut & pull turning. |
PA |  |  | Finish turning for steel | Recommended chipbreaker for steel finishing. Segmented chip breaker platform realizes reliable chip breaking under different depth of cut. Sharp cutting edge with positive inclination angle lowers cutting resistance and optimizes chip flow direction. |
PB |  |  | Semi-finish turning for steel | Recommended chipbreaker for steel semi-finishing. Combination of flat land and large rake angle on rake face balances cutting edge strength and sharpness. Large inclined angle at tip reduces cutting resistance. Wavy flank performs well on chip breaking for wall pull turning, ideal for profiling with variable cutting depth. |
PC |  |  | Medium turning for steel | Recommended chipbreaker for steel semi-finishing. Tapered cutting edge (narrow front, wide rear) provides wide chip breaking window. Double rake angle design for light cutting. Reinforced tip for strong resistance against crater wear. |
PL |  |  | Medium turning for steel | Recommended chipbreaker for steel semi-finishing. Tapered cutting edge (narrow front, wide rear) provides wide chip breaking window. Double rake angle design for light cutting. Reinforced tip for strong resistance against crater wear. |
PM |  |  | Rough turning for steel | Recommended chipbreaker for steel roughing. Small land near tip ensures good chip breaking under shallow cut and strengthens tool nose. Double rake angle design effectively reduces cutting resistance. |
