Sandvik Coromant – How to reduce vibration in metal cutting 28
Practical tips and hints on
how to reduce vibrations
Milling Cutter Body
1. Choose the smallest or lightest cutter body possible.
2. Try to balance the radial and axial cutting forces by using a smaller
entering angle. E.g 45 or 10 degree. Or maybe a round insert cutter.
3. Choose a milling cutter with a coarse tooth pitch and a positive design.
4. Choose differential pitch.
5. Choose a milling cutter with internal coolant holes for proper supply.
Adaptor Type and Size
1. Choose the shortest possible adaptor. Every millimetre is important.
2. Choose the largest possible diameter/size of the adaptor
3. For small milling cutters use if possible a tapered adaptor.
4. If possible use Coromant Capto instead of a weaker coupling type.
5. For shank couplings and short overhang use a high clamping force
adaptor, e.g CoroGrip.
6. For shank couplings and a bit longer overhang it can sometimes be
beneficial to use power chucks/collet chucks.
7. For longer overhang (>5xD) use a damped adaptor, a Silent Tool.
