Sandvik Coromant – How to reduce vibration in metal cutting
Turning - Rotating
Introduction
Vibration in metal cutting is familiar to every machine tool operator. This
phenomena is recognised in operations such as internal turning, threading,
grooving, milling, boring and drilling, to which there are several reasons
why this problem occurs. Some are related to the machine tool itself, to the
clamping of the tool, the length and diameter of the tool holder and the
cutting data to be used. More of this will be discussed later.
There will be several different actions to consider when solving this pro-
blem. Reducing the process parameters is one such consideration, however,
this could have a negative effect on productivity. Our focus, therefore, will
be easy hands on recommendations for productive solutions and easy to
use products. This strategy will be emphasized throughout this guide
which will also contain useful information relating to the tool holder e.g.
clamping methods, extensions and the types of inserts that can be used.
Stretching beyond the normal limit of 4 x the L/D (Length by Dia-
meter) ratio is possible when using a Silent Tools tool holder.
Silent Tools is a Trade Mark for a family of tool holders for turning,
milling, boring and drilling with a damper inside to minimise the problems
with vibration. You will find more information about these damped adap-
tors in a separate chapter. Products with a similar function can be referred
to as tuned, damped or anti-vibration tools.
The aim, with this application on hand, is for you to have easy access to
information giving you productive solutions for eliminating vibrations in
your metal cutting process.
