Sandvik Coromant – How to reduce vibration in metal cutting 25
Silent Tools
Productivity with slender tools
When machining deep cavities or with long overhangs you can be faced
with vibration problems. One way to overcome this is to reduce the depth
of cut, the speed or the feed.
Losing productivity in favour of keeping the process running is not bene-
ficial.
Productivity is the number one important issue in being competi-
tive. The use of a Silent Tool when going deeper into a bore, will retain,
or in many cases improve your productivity. You can keep your depth of
cut, the same feed and speed and have a high quality surface finish, closer
tolerances and improved tool life even when working with boring bars with
overhangs from 7 up to 14 times the bar diameter.
Silent Tools are a family of products for internal turning, milling, boring
and drilling. These products are damped to work on overhangs beyond the
limitation of solid steel and solid carbide shanks. They are easy to operate
and are very flexible due to the wide variety of back-end and front-end
couplings.
