Tools for cutting off and recessing

The offer of the tools for parting off and grooving is gradually being enlarged. The older generation of indexable cutting inserts, suitable mainly for material division, is being replaced by new types for lighter operation of parting off and grooving (LFMX) and for internal grooving and copy turning (LCMF). Similarly, the new T8330 grade with PVD coating from the new UP!GRADE line proves successful as a replacement of well-proven 8030.

The GFI tools for the LCMF indexable inserts represent a modern solution for shallow grooving into depth corresponding to triple of the width of the indexable cutting insert. The assortment has newly been completed with GFM holders for the LCMR inserts corresponding to quintuple of the width of the indexable cutting insert and GFK tools and GFK holders for the LCMF cutting inserts of 2 mm width enabling parting off and grooving up to 16 mm depth. The tools for the LCMF inserts combine a possibility of grooving and copy (multidirectional) turning.
We offer the tools with theLFMX inserts for middle-deep and deep parting off and grooving. There are also geometries for fine and rough operations as well as inserts with straight and inclined cutting edge in the assortment. The offer of the inserts ranges from 1.6 mm to 6.35 mm.
A part of the offer is also a complete assortment for slot turning for lock rings (0.9 to 4.15 mm widths) and sealing rings (R0.5 to R1.5 mm). The inserts are clamped into holders for threading and they also have that kind of specification. Instead of lead of thread, the width of groove is given and the profile is ZZ specified (e.g. TN 16ER110ZZ). It is necessary to use a shim with ZZ specification or a tool with 0° inclination angle for grooving.
