The fact that SCHUNK primarily designed
the TRIBOS-Mini used in these milling
operations for drilling, rather than milling,
has hardly any effect on small cutting
diameters. On the contrary, “The slim
interfering contour of the toolholder
mounting allows excellent accessibility
without excessive tool overhang. It
stabilises and dampens the vibrations on
the tool,” says Uwe Walikewitz. “We tested
the mounting and immediately installed
it on three automatic lathes.” For Uwe
Walikewitz, the investment quickly paid off,
not only because it has reduced cycle time,
it has also improved process reliability in
automatic mode, lowered tool costs and
improved the quality of surfaces. “With
TRIBOS, the surface is much finer than with
collet chucks,” says the lathe chuck expert.
QUICK SETUP AND PRECISE
ADJUSTMENT
Tools can be preset in the TRIBOS mounting
at an accuracy of 0.01mm in length and
exchanged in the collet chuck in just a few
steps. In this way, the user benefits from
fast set-up times and much higher repeat
accuracy in the clamping system in terms
of run-out accuracy and projecting lengths
compared to ER collet chucks. A complete
tool change only takes 20 seconds.
SLIM OR POWERFUL
TRIBOS polygonal toolholders with ER
tapers come in two different versions:
The slim TRIBOS-Mini ER is ideal for micro
cutting, and sets the benchmark when
it comes to small shank diameters. It is
available in sizes ER 11 (clamping diameter
1 to 4mm), and ER 16, ER 20, ER 25, and R
32 (clamping diameter 1 mm to 6 mm).
TRIBOS-RM ER, on the other hand, is
perfectly suitable for precise high-volume
machining at high rotational speeds.
