Feed per tooth: fz (mm/t)
High feed rate & high
cutting effi ciency!
TECMILL features unique tangential clamping.
Thicker body core provides tangential clamping
and improves body rigidity.
Tangential clamping dramatically improves cutting
edge and body strength.

· To remove excessive chip accumulation use an air blast.
· When cutting interrupted surfaces like a casting skin, the cutting feed (fz)
should be set below the values shown in the above table.
· Tool overhang should be minimized. When machining with long overhang

· Cutting conditions are limited by machine power and material rigidity. When
the cutting width or depth is large, set Vc and fz below the recommended
values and check the machine vibration and spindle load.
