Operating Instructions for the Clamping Mechanism
Fig. 1
Adjustment pin
Set the eccentric clamping element to the "off"
position with hexagonal key (as far as the stop). The
clamping mechanism is then released and the boring
bar can be changed (Fig. 1). Insert the new boring
bar into the clamping holder as far as the stop with
the flat surface upwards.
Fig. 2
Adjustment pin
Tighten the eccentric clamping element with the key
to a maximum of 3 Nm (Fig. 2).
By turning the eccentric clamping element, the
boring bar is pushed out of the holder in the axial
position (±0.01) and at the same time moved into
the exact centre height (±0.01).
A click will indicate that the clamping mechanism
has been released.
Recommended guideline values
for boring, chamfering, copying and grooving
Feed f = 0,01-0,025 mm
Note: The application details shown depend on the environmental and application conditions
(e.g. machine, ambient temperature, use of lubricant/coolant and the machining
result required). These are subject to correct operating conditions, correct application and
compliance with the spindle speed limits given for the tools.
