Maintenance instructions
The reliability of the clamping device can only be guaranteed if the
maintenance instructions in the operating manual are precisely
followed. Please observe the following in particular:
• For lubrication of the clamping device, we recommend using
our proven high-performance grease LINOMAX. Unsuitable
lubricants can have a negative impact on the functioning of the
clamping device (clamping force, coefficient of friction, wear
behavior).
• All surfaces to be lubricated must be reached during
lubrication. (The tight fittings of the components require a high
injecting pressure. Therefore use a high-pressure grease press.)
• For good distribution of the grease, move the chuck to its end
positions several times, lubricate again, and then check the
clamping force.
• We recommend checking the clamping force using a clamping
force tester (e.g. GFT 270, ID 0890013) before starting a new
production run and between maintenance intervals. "Optimum
safety can only be guaranteed through regular checks".
• The clamping force should always be measured in the state of
the chuck as used for the current clamping situation. If top jaws
with clamping steps are used, clamping must be done in the
same step as for the respective clamping task. In the event of
high operating speeds, clamping force losses must be
accounted for due to the centrifugal force. In this case the
value of the operating clamping force should be measured
dynamically.
• It is useful to travel the clamping piston through to its end
position several times after 500 clamping strokes, at the latest.
(Removed lubricant will be pushed back to the pressure
surfaces again so that the clamping force is retained for longer).
