TAC Mills
Notes: • Wet cutting is recommended. Use a water-soluble cutting fluid.
• Dry cutting is also possible. However, wet cutting excels in chipbreaking and attaining superior surface quality.
Cautionary points for use
To avoid the danger of unbalanced revolution, the TAC
mill should not be used in a state of reduced number of
inserts.
Use the cutter within the maximum revolutions written on
the cutter body.
When using the cutter at a cutting speed less than v c =
1500 m/min, the balance quality of the arbor
and toolholder should be prepared within class G16.
When installing the inserts, recommended clamping
torque for the wedge fixing screw is 9.8 N·m.
