Round inserts ‘promote better profiling'

Round inserts ‘promote better profiling'Cutting-tool and tooling-system specialist Sandvik Coromant is adding round geometry (-RM) inserts to its programme of CoroCut QD parting-off and grooving tools.

The company (www.sandvik.coromant.com)says that round geometry allows profiling with long overhangs in narrow grooves; further applications include external profiling, generating recesses and undercuts — and the potential to use non-linear turning and grooving with a ‘full-radial bottom’.

Angélica González, global product manager (turning tools), said: “The features and benefits of using round-geometry inserts with CoroCut QD holders include better tool life and chip control with a rigid insert seat, internal over- and under-coolant for improved process security and chip evacuation, and the potential for use with a Y-axis blade.”

Dr González says that a customer case example demonstrates the potential gains on offer. “A shaft made from 42CrMo4
alloy steel required grooving operations on a Niles-Simmons N30 CNC lathe.

"Using a CoroCut QD holder with -RM geometry inserts in place of a competitor solution saw tool life doubled — and far better chip control.

The cutting data was identical for both tools: 290rev/min spindle speed; 160-180m/min cutting speed; 0.3mm/rev feed rate; and 2.7mm axial depth of cut.”

Three grades are available for the inserts. GC1125 grade is ‘ideal’ for finishing in all materials, as well as certain roughing operations in non-ferrous metals, heat-resistant super-alloys (HRSAs) and titanium; GC1135 grade is the ‘first choice’ for roughing in stainless steel and HRSAs; while GC4335 grade is recommended for roughing steel and cast-iron workpieces.

The inserts are available in four sizes — 3, 4, 6 and 8mm.
