1. Introduction
Choose the right tool
Choosing the correct tool is important to achieve best possible pro-
ductivity and results. There is always an optimized solution for each
length/diameter overhang and the dampening system is tuned to
run optimally in specified conditions.
Each dampened tool has a defined range of reach (bandwith) for
optimum tool function and it is important that the right range for
each tool is applied. Using a short tool with an extension will not
deliver desired results.
Increasing the static stiffness of the cutting tool will make it pos-
sible to increase chip removal rate and productivity, without facing
vibration problems. Look for standard tools giving you an assembly
with minimum lengths and maximum diameter. Both parameters
are equally important.
If it is a modular tool; build it so that the biggest diameter is clos-
est to the machine side.
Working area specification
There is a potential to increase productivity by using dampened
tools from 3 x BD (Body diameter) and up.
For 4 x BD, cutting data can usually be increased by more than 50%
by using a dampened tool and from 6 x BD, dampened solutions
are the only choice to achieve good productivity, hole quality and
surface finish.
When your application requires lengths, diameters, couplings and
other specifications outside the standard, off the shelf-tools, ask
for an engineered solution for best performance.
