The ValTurn turning system has added three top from geometries to its turning tool inserts. The geometries are combined with two existing MTCVD coated tooling grades, VP5515 and VP5525, to extend the potential application range of the three ValTurn tools, targeting those for medium loads with continuous or interrupted cuts, for heavy load roughing applications and for low depth-of-cut finishing operations in low carbon steels or gummy materials.
All three top forms are ANSI negative-type geometry and are double-sided inserts. The selection contains various insert shapes, thickness, inscribed circle, corner radius and more. The geometries include M8 designation, R4 designation and C2 designation.
The tool grades are MTCVD-process coated carbide. The substrate is enriched with cobalt to provide resistance to edge chipping and the insert has polished cutting edges to prevent material build-up.
