Deep grooving and profiling
Discs and spool components have deep
cavities which have to be machined from
solid or finish machined after welding. The
long depth to width ratio required for the
tool means that there is a high tendency to
vibration.
The blade solution is developed to optimize
this difficult application offering maximum
rigidity and minimized vibration allowing
high productivity where long slender tools
are required.
• Dampened mechanism incorporated in
the blade.
• Coromant Capto ® (C6 or C8) spindle
adaptor.
• Oval shaft.
• Serration coupling.
• High blade.
• Over and under coolant.
Dampened mechanism
A patented solution is applied when the blade length to
width ratio is greater than 5:1. Carbide discs are assem-
bled into the blade which opposes the vibration induced
by the cutting process. The effect is that typically 4
times greater depth of cut can be achieved.
