Slotting cutter, cutting insert and tool therefor

摘要

A slotting cutter includes a disc-like cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body. The cutter body includes a stop slot, an upper cam slot and a lower slot. A plurality of pockets adapted to receive a cutting inset are formed about a perimeter of the body. A cantilevered clamping member includes a bottom surface with a pair of clamping surfaces that engage a pair of angled clamping surfaces on a top surface of the cutting insert during operation. A wrench is provided to lift the cantilevered clamping member for inserting, indexing or removing the cutting insert from the slotting cutter. The wrench includes two fixed pins and a floating pin that prevents the cantilevered clamping member from bending too far and limiting the useful life of the slotting cutter.

主权项

1. A slotting cutter, comprising:
a disc-like cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body, the cutter body also includes an upper cam slot defined by a pair of opposing lower and upper surfaces, a lower slot defined by a pair of opposing lower and upper surfaces, and a stop slot disposed between the upper cam slot and the lower slot and defined by a pair of opposing, curved lower and upper surfaces, each slot adapted to engage a wrench; and a cantilevered clamping member having a bottom surface adapted to engage clamping surfaces on a top surface of a cutting insert when the cutting insert is mounted in a pocket of the slotting cutter.
