DURO-A RC 9 / 48
2.1 Intended Use
The power chuck DURO-A RC is used to clamp regularly and irregularly
shaped workpieces. Only metal workpieces may be clamped in the power
chuck DURO-A RC. Other materials are only permissible by arrangement with
RÖHM GmbH.
To ensure safe clamping of the workpiece with the machining forces which oc-
cur, 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 RC, the max-
imum permissible actuating force and speed must be observed (
Overview of
Construction Sizes [ } 19] ).
The power chuck DURO-A RC may be installed in machine tools for cutting
and non-cutting processes. The power chuck DURO-A RC may be installed
and used both horizontally and vertically. Stationary machining without rota-
tion of the power chuck DURO-A RC is permitted. Locking and unlocking is
only permitted with the original safety key of RÖHM GmbH.
The DURO-A RC is a power chuck with individually adjustable jaws. Only ori-
ginal RÖHM base jaws and original RÖHM one-piece jaws may be used.
Third-party makes may impair the safety of the power chuck DURO-A RC 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 or larger or if they are 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 power chuck DURO-A RC can be used for both wet and dry machining.
The permissible usage and environmental conditions must be observed
(
Environmental and Operational Conditions [ } 20] ).
The power chuck DURO-A RC is only intended for commercial use.
