2 Safety
Safety instructions and safety equipment serve to prevent accidents and
damage when working on the power chuck. The safety instructions contain
warnings and basic safety instructions. In addition to the safety instructions
in this chapter, the following chapters contain action-related warnings. Max-
imum protection of personnel and the environment from dangers and
trouble-free operation is only possible when all safety instructions and warn-
ings in this operating manual are observed.
2.1 Intended Use
The power chuck DURO-A is used to clamp regularly and irregularly shaped
workpieces. Only metal workpieces may be clamped into thepower chuck
DURO-A. Other materials are only permissible by arrangement with RÖHM
GmbH.
To ensure safe clamping of the workpiece with the machining forces occur-
ring, the clamped material must have adequate rigidity for the clamping force
and may only be slightly compressible. The clamping force is given in the
clamping force diagram (
Clamping Force-Speed Diagram [
}
21] ).
Depending on the construction size of the power chuck DURO-A, the max-
imum permissible actuating force and speed must be observed (
Overview of
Construction Sizes [ } 19] ).
The power chuck DURO-A may be installed in machine tools for cutting and
non-cutting processes. The power chuck DURO-A may be installed and used
both horizontally and vertically (standing or suspended). Stationary machin-
ing without rotation of the power chuck DURO-A is permitted.
Only original RÖHM base jaws and top jaws may be used. Third-party
products may impair the safety of the power chuck DURO-A and lead to
damage.
The jaws used must comply with the following specifications:
▪ The jaws must be designed as light as possible;
▪ The clamping point of the jaws must lie as close as possible to the
power chuck.
▪ The jaws must be adapted to the size (equal or smaller), the weight
(equal or lighter) and the rigidity (equal or higher) of the jaws assigned
to the power chuck. If the jaws are heavier, larger or less rigid than the
jaws assigned to the power chuck, the higher centrifugal force and the
higher load of the power chuck must be taken into account. The neces-
sary clamping force and maximum speed must be reduced.
The maximum permissible clamping diameter of the jaws and the limits of
the jaws must be observed.
The DURO-A may only be operated when the guard is closed (exception:
set-up mode).
