Abstract
The invention relates to a disc-shaped or strip-shaped tool for machining, particularly, for cutting profiles on a workpiece such as a crankshaft that is rotated during machining, comprising a number of tangentially and radially mounted indexable inserts (21). According to the invention, at least a part of the tangentially mounted indexable inserts (21) has a recess (31) that, in the tangentially mounted indexable insert (21), extends into a portion of the supporting surface (27, 28) and into a portion of the radially situated face (23, 24), and into which an upper rear section of a radially mounted indexable insert projects whose upper front section (32) radially protrudes with regard to said face (23).
Claims20
A disk-shaped or bar-shaped tool for machining, in particular for cutting profiles in a workpiece such as a crankshaft that is rotated during machining, having a plurality of tangentially and radially mounted indexable inserts, characterized in that
- at least a part of the tangentially mounted indexable insert (21) has a cutout (31) that, in the tangentially mounted indexable insert (21), extends into a portion of a support face (27 and 28) and into a portion of the radially oriented face (23 and 24), and into which an upper rear portion of a radially mounted indexable insert (13) projects whose upper front section (32) radially projects with regard to the face (23).
The tool in accordance with 1, characterized in that the tangentially mounted and the radially mounted indexable inserts (13 and 21) are mounted in a cassette.
The tool in accordance with 1, characterized in that all indexable inserts are made of a hard metal or a cermet body that has been produced using powder metallurgy by pressing and then sintering without intermediate mechanical processing.
A machining tool comprising:
- a support having a longitudinally extending outer surface and a side surface;
- a row of tangentially mounted indexable inserts secured to the outer surface and each formed with
- oppositely directed broad faces,
- a pair of longitudinal side faces bridging the broad faces,
- a pair of transverse side faces-bridging the broad faces,
- a cutout extending into the side face and the support face;
- means for securing the tangential inserts to the support in a row with each of the tangential inserts bearing with one of the broad faces on the support outer surface, the other broad face turned away from the support, one of the longitudinal side faces extending generally parallel to and projecting transversely past the support side surface, and the cutout open toward the support outer face;
- and
- respective radially mounted indexable inserts secured to the side face immediately adjacent each of the tangential inserts and each having an end portion seated in the respective cutout, the radial inserts projecting transversely from the cutouts of the respective tangential inserts.
