CUTTING PLATE WITH SCREW SURFACE FOR CHIP EXIT

摘要

FIELD: mechanical engineering. SUBSTANCE: front surface of the plate is screw. The front clearance angle decreases from an operating angle up to a point on the cutting edge and increases from this point up to adjacent angle. Each cutting angle has an auxiliary cutting edge to form worked surface of a member. EFFECT: improved design, enhanced strength. 9 cl, 3 dwgl
