Metal cutting tool and cutting plate provided in the shape of a donut
09744598 · 2017-08-29 · ·

A metal cutting tool has a supporting tool, which has a recess for accommodating a cutting plate. The cutting plate is provided with a clamping trough, which is held in the supporting tool by a clamping claw. The clamping claw is fixed against the supporting tool by a clamping screw. A pressure piece is placed on the clamping claw and its underside facing the cutting plate is provided with a cam, which is in contact with the clamping trough and the clamping claw pulls the pressure piece toward the clamping screw.

Tip dressing cutter
09770779 · 2017-09-26 · ·

A low-cost tip dressing cutter causing no accumulation of swarf around a breaker is provided. A surface of a breaker 5 facing a cutting plate 4 corresponds to a recessed surface 52. The diameter of the recessed surface 52 gradually decreases with increasing distance from the outer periphery of the recessed surface 52 facing the cutting plate 4 in a direction opposite to the cutting plate 4. A through hole 51 is formed at the center of the breaker 5, A screw 6 inserted through the through hole 51 is screwed to a fastening hole 33a of a holder 3 to attach the cutting plate 4 to the breaker 5.

09592562 · 2017-03-14 · ·

A cutting element for use in a cutting operation, comprising a cutting edge (CE) capable of cutting out material from a workpiece during the operation, to form therein a workpiece corner of angle alpha. There exists at least one view of the cutting edge in which a portion of the cutting edge is delimitable by a first (L1) and a second (L2) line oriented tangentially to the portion of the cutting edge portion at respective tangency points A and B. The lines form therebetween a cutting angle corresponding to the workpiece corner angle alpha and have a vertex 0. For a bisector of the cutting angle intersecting the portion of the cutting edge at the point C, the projection C of the point C of the portion of the cutting edge on a line OL passing through the vertex 0 perpendicularly to the plane of the one view is located between projections A1 and B of the respective points A and B of the portion of the cutting edge on the line OL.
