Sandvik Coromant – How to reduce vibration in metal cutting 41
Choice of holding tools
• Use stiff modular tools with
good run-out accuracy
• Modular tools increase the flexi-
bility and the possible number
of combinations – use largest
possible diameter on holding
tools (extensions, adaptors)
relative to cutter diameter
• For spindle speeds over 20,000
rpm use balanced cutting and
holding tools
Long overhangs
The Coromant Capto ® modular holding tool system allows combinations
of long or short basic holders, extensions and reductions to an assembly of
required length, with high stability and smallest run-out.
– maintain max productivity by
choosing a series of extension
modules for the roughing
cutter set-up
– change extensions at
pre-determined positions
– adapt cutting data for each
tool length
– use damped, tapered bars for
overhangs >4 - 5xD
