6.2 Notes on clamping and unclamping
• Due to the manufacturing and material tolerances, it is possible
to insert or loosen tools or work pieces even at a pressure
below that indicated on the TRIBOS toolholder.
•
This lower pressure value may be significantly less than that
stipulated on the toolholder.
However, this has no influence on the transmissible torque of
the toolholder (see operating manual TRIBOS polygonal tool
holder).
• Please make sure that the tool/work piece is still clamped in the
toolholder at this time, if the actual unclamping pressure of the
clamping device was exceeded! It is also possible that the tool
can no longer be inserted into the toolholder at the indicated
pressure, but instead at a value that is a few bars below it!
• Continually check the pressure in the clamping device at which
the tool/workpiece can be inserted or removed from the
toolholder.
• If it proves impossible to loosen or insert the tool or work piece
from or into the toolholder until the indicated pressure is
achieved, stop the clamping procedure. Release the pressure of
the clamping device first and then check that any play between
the flattened area of the toolholder and the reduction insert is
eliminated by turning the toolholder to the right
(clockwise).Repeat the clamping procedure.
• If it proves impossible to loosen or insert the tool/work piece,
even though the toolholder is inserted correctly in the reduction
insert, unclamp the device and remove the reduction insert and
the toolholder. Turn the reduction insert on the toolholder by
120°, push it into the clamping device again and repeat the
clamping procedure. It should now be possible to loosen the
tool/work piece.
• The tool can become stuck in the toolholder as a result of fine
particles in the cooling lubricant. If this is the 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.
• Sometimes, the tool shanks are marked. These markings are
often "wrapped". This impairs the insertion of the TRIBOS
toolholder or even makes an insertion impossible. In this case,
re-move the wrapping.
