Grooving
Choosing the correct tool for the application
Choice of tooling family:
CoroCut for grooving hole diameter from 25 mm
T-MAX Q-Cut for grooving hole diameter from 20 mm
CoroCut MB for grooving hole diameter from 10 mm
CoroTurn XS for grooving hole diameter from 4.2 mm
Chip evacuation:
To avoid chip jamming within grooving operations it is important to direct
the coolant into the groove and evacuate the chips. Chips in the groove
can cause insert breakage, bad surface finish or difficulties in keeping
tolerances. For this to be effective it is recommended to choose toolholders
or cutting heads with integrated coolant.
It is also possible to change the programming of the machine with micro
stops so that chip breaking can be achieved and the evacuation of chips is
made possible.
Overhang:
Compared with turning, grooving is limited to a certain overhang due to
the increased side (radial) forces. We recommend, therefore, you choose
Silent Tool holders or carbide reinforced so that the productivity can be
increased.
