• Fine particles in the cooling lubricant may cause the tool to
become stuck in the toolholder. In this case, insert a piercer
through the rear opening of the TRIBOS toolholder and loosen
the tool by pushing or gently hitting it with this piercer.
• Some tool shanks are marked. These markings are often
"wrapped". This impairs the insertion into TRIBOS toolholders
or even make an insertion impossible.
• Tool shanks with recesses, especially DIN 1835 shape E or DIN
6535 shape HE, are often deformed and thus sometimes cause
problems inserting them into the TRIBOS toolholder or impair
the run-out accuracy. The same applies, if tool shanks fall below
(no torque) the h6-quality or exceed it (cannot be inserted).
For clamping shanks of shape E or HE, please observe the position
of the recesses to the pressure segments:
SRE-Pressure segment
Toolholder
Shank
DIN 1835 E
DIN 6535 HE
In this shank position in the TRIBOS toolholder, the clamping
surfaces fit closely to the round shank and in this way a similar
effect to the one of a "round shank clamp" is achieved. In order to
avoid a deformation of the tool shank, the hardness at the shank
should be at least HRC 50 (shank stifness at least 1000 N/mm
2
). In
case of a lower hardness or stiffness, the compression joint is not
covered properly which leads to a reduced force transmission of
the clamping system.
