Screw tightening torques
Tightening torques for fastening the clamping station with the
cylindrical clamp blanks.
The clamp blanks that have been adjusted by the customer to
correspond to the machine table must be fastened to the machine
table with fastening screws of strength class 10.9. These fastening
screws and any nuts required for the T-slots are not included in the
scope of delivery.
Note:
The clamping stations should preferably be fastened with M4
screws in connection with the clamp blanks.

CAUTION
Notes on clamping pins and mounting screws
The holding force of the quick-change pallet system is limited
essentially by the tightness of the screw connection which
connects the clamping pin to the pallet or the device. This is why
only screws of strength class 12.9 may be used.
•
Only original SCHUNK clamping pins may be used.
•
If the clamping pins are to be used in customer-owned
devices, the customer must provide sufficiently dimensioned
threaded holes or a sufficiently thick mounting material.
