INSTRUCTIONS FOR SAFETY-CONSCIOUS WORK
4 Instructions for safety-conscious work
All specifications in the user documentation as well as the applicable
directives and regulations must always be observed. For integrated com-
ponents made by third parties, the user documentation of the respective
manufacturers must be observed as well.
4.1 Handling of workpieces
4.1.1 Clamping the workpiece
The clamping system forms the interface between the machine and the workpiece
and serves to absorb the forces occurring during the machining process. For this
reason, the clamping system is of particular importance.
The shape and mass of the machined workpiece before, during and after machining
are vitally important. Therefore, workpieces must have a balanced mass. For unbal-
anced workpieces, the clamping device must be adapted appropriately.
In general:
• Only clamping devices that have been approved by the machine manufacturer may
be used.
When in doubt, the machine or clamping device manufacturer should be consulted.
• The clamping device must be dimensioned and used according to the specifi-
cations in the (third party manufacturer’s) user documentation and applicable
directives.
• All components of the clamping system must be maintained in proper and func-
tional condition.
• The maximum permitted rotational speed must be limited. In this regard, the
lowest permissible rotational speed of all components involved (clamping device
or workpiece) determines the maximum permitted rotational speed. The ro-
tational speed limitation must be stored in the controller and written into the
machining program.
• When using chucks (jaw chucks), the maximum permissible speed must be
calculated (taking into account the resistance class of the respective machine).
It is recommended that the maximum permissible speed always be
calculated using the software (calculation aid for speed limitation)
stored in the controller. The respective resistance class of the ma-
chine is stored in the software.
The specifications in the applicable user documentation must be
observed.
• The prescribed rotational speeds must be adhered to.
• Components of the clamping system may only be modified after consultation
with the machine manufacturer.
• Remove chips only with suitable auxiliary equipment.
