For face grooving, create curled chips under the lower limit of the recommended cutting conditions. Recommended Cutting Conditions for GNDIS Type F37
For cut-off, reduce the feed rate to 30% to 50% around the center of the workpiece. For boring (for small holes in particular) ML, GL or GF type chipbreakers are recommended since the chip discharge area is small.) To perform facing with a RG type chipbreaker and a GNDF type holder, the insert and holder may require modification for radius grooving and other machining applications. ■ Recommended Cutting Conditions
