10 / 52 Power Chuck DURO-A
The power chuck DURO-A can be used for both wet and dry machining. The
permissible usage and environmental conditions must be observed (
Envir-
onmental and Operational Conditions [
}
20] ).
The power chuck DURO-A is only intended for commercial use.
2.2 Improper Use
If the power chuck is operated for a purpose other than the intended use as
specified in this operating manual, this is deemed to be improper use.
Any utilisation beyond the scope of the intended use poses risks and is not
approved by RÖHM GmbH.
Improper use refers to the following:
▪ Use of the power chuck DURO-A for suspending loads;
▪ Use of non-OEM parts as replacement parts;
▪ Use of defective jaws (e.g. sprockets on base jaw broken off or cracks in
the jaws);
▪ Use of welded jaws;
▪ Use of the power chuck DURO-A in explosive atmospheres;
▪ Operation with modifications not approved by the manufacturer;
▪ Operation outside of the defined operating parameters;
▪ Operation with insufficient maintenance;
▪ Operation without or with insufficiently clamped workpiece;
▪ Clamping of unsuitable materials (compressible materials);
▪ Clamping of unauthorised materials (plastics, rubber, glass or other non-
metals) without the approval of RÖHM GmbH;
▪ Direct pointing of compressed air or coolant spray at guide gap or lubric-
ating nipple;
▪ Clamping of regular workpieces with an asymmetric position of the jaws;
▪ Clamping of workpieces which are too heavy or too long (see document
"RÖHM Standard RN 1391 - General Information and Guidelines for the
Use of Power-Operated Clamping Devices”)
Basic Principles [

▪ Clamping of workpieces with a clamping diameter > chuck diameter;
▪ Eccentric clamping of workpieces ( Dangers due to Imbalanced Work-
pieces [ } 14] );
▪ Removal of swarf during operation;
▪ Operation without effective safety equipment;
▪ Assembly of the power chuck and accessory parts with incorrect torque
(see Checking the Tightness of Screw Connections [ } 42] ).
