Lead to blades fail, increases edge strength, while segmentation and protective effect are risen to major-minor cutting edge, improve cutting edge resisting breakage
Performance；Blade rake face is equipped with raindrop shape protrusion, and chip can be improved blade chip breaking ability, slow down preceding knife when flowing through raindrop shape protrusion
Surface wear；Reduce chip and tool contact area simultaneously, increase the effective heat dissipation area of cutter, reduces cutting temperature.
5, blade flank is the knife after the main flank of blade and pair with workpiece to be machined material surface primary contact regions
Face separately designs microflute texture can reduce tool-workpiece contact area during the cutting process, reduce blade and workpiece material surface
Coefficient of friction reduces frictional force, reduces cutting zone temperature, avoids the occurrence of sticking phenomenon；Micro groove structure can effectively press down
Tool wear processed can collect the minute impurities such as the abrasive dust generated in friction process, thus improve workpiece machining surface quality and
Cutter life.
6, it is equipped with cooling groove on square protruding platform, the area of blade upper surface can be effectively increased, reduces knife-bits
Contact area, to accelerate shedding for heat in cutting process；Energy volume coolant liquid, infiltrates fastening screw in cooling groove
In coolant liquid, fastening screw can not only be protected, avoids that fastening screw and knife bar or cutterhead is caused to bond because of high temperature, moreover it is possible to make knife
Piece is quickly cooled down.
7, blade is mounted on turning tool rod or facing cutter by the fastening screw counterbore at blade geometric center, it can be fast
Fast rotating blade improves the service efficiency of blade；Simultaneously can play the role of fixing to clamp, prevent blade in process by
It rotates or slides when effect by cutting force or frictional force.
