Safety

Safety instructions and safety equipment serve to prevent accidents and dam-
age when working on the centric clamp. The safety instructions contain warn-
ings and basic safety instructions. In addition to the safety instructions in this
chapter, the following chapters contain action-related warnings. Maximum
protection of personnel and the environment from dangers and trouble-free
operation is only possible when all safety instructions and warnings in this op-
erating manual are observed.

2.1

Intended Use

The centric clamp KZS-H/KZS-HG is used to clamp regularly and irregularly
shaped workpieces.

▪ In the case of special workpiece geometries, corresponding top jaws must

be used.

▪ In the case of irregular workpieces, compensatory clamping jaws must be

used.

▪ In the case of vertically non-parallel workpieces, pendulum jaws

(inserted vertically) must be used.

▪ In the case of horizontally non-parallel workpieces, pendulum jaws

(inserted horizontally) must be used.

▪ In the case of unmachined parts with a tendency to lift, claw jaws must be

used.

The workpieces to be clamped must have a sufficient strength for the clamp-
ing force and minimum compressibility. Other materials may only be used with
the agreement of RÖHM GmbH. Clamping of imbalanced workpieces is per-
missible. Imbalanced workpieces must always be clamped in the centre of the
top jaws. The centric clamp is suitable for internal and external clamping of
workpieces. Clocking up to a maximum speed is permitted up to 60 rpm.

The centric clamp

▪ may be installed in all machining centres and processing machines for

cutting and non-cutting processes.

▪ may be installed both horizontally and vertically.

▪ may be operated in a stationary position.

▪ may only be operated when screwed on (e.g. on a machine table or ma-

chine pallet).

The clamping force may only be introduced hydraulically via the internal cylin-
der piston.
