3. Controls
1. Stroke control:
When the clamping device has been changed,
the stroke control must be adjusted to the new condition.
2. Maintenance controls:
The reliability of clamping equipment
can be ensured only if the servicing instructions of the manual
are obeyed exactly.
4. Environmental Hazards
A wide range of media are required during operation of a clam-
ping device for lubrication, cooling etc. This are normally distri-
buted to the clamping device via the distribution housing. The
most common substances used are hydraulic oil, lubricating oil/
grease and cooling agents. When handling the clamping device
care must be taken to ensure that these substances do not
come in contact with the soil or water. Warning, environmental
hazard!
This applies in particular
- during assembly/disassembly, as residues can be contai-
ned in the pipes and piston shafts,
- to porous, defective or incorrectly mounted seals,
- to lubricants which are emitted or ejected from the clam-
ping device during operation for constructional reasons.
These discharged substances should therefore be collected and
either re-used or disposed of in accordance with valid regula-
tions!
5. Safety requirements for power clamping equipment:
5.1 The machine spindle may not start until the clamping
pressure has been reached in the clamping cylinder and
clamping has been effected within the permissible wor-
king range.
5.2 The pressure may only be released when the machine
spindle is stationary.
Exceptions are only permissible if the complete machi-
ning sequence of loading and unloading is performed
with the spindle in motion and the design of the distribu-
tor/cylinder permits this.
5.3 A signal must be emitted to stop the spindle immediately
in the event of a failure of the clamping power.
5.4 The workpiece must remain tightly clamped until the
spindle is stationary in the event of a failure of the clam-
ping power.
5.5 Changes of the current switch position should not be
possible during an electrical power failure and subse-
quent restoration.
6. Spare Parts
Only use ORIGINAL RÖHM spare parts or components ob-
tained from authorised RÖHM suppliers. RÖHM GmbH does
not accept any liability for damage resulting from the employ-
ment of parts supplied by other manufacturers.
Note: For simple ordering of spare parts or individual com-
ponents always state the 6-digit ID number engraved on the
assembly and, if available, the works number. This compri-
ses a letter with two digits and possibly a series number,
stated either on the rating plate or next to the ID number.
