Foreign matter penetrates into practically every power chuck during machining. Chips, scale and
foundry dust increase the friction between moving parts and coolant washes away the lubricants
The chuck sealing can only delay it, therefore the power chuck must be checked regularly and cleaned
if required and filled with fresh lubricant.
Filling through the oil holes in the chuck body (see above). Oil quantity max. 75% of the cavity volume.
This will ensure uniform chucking force, accuracy and high service life.
The lubrication of the - actuated by the hydraulic oil cylinder - power check must be
done at regular intervals. Due to this reason, carry out many empty runs (without work
piece), to distribute the lubricant evenly.

FILL THE POWER CHUCK WITH LUBRICANT AT THE MARKED
HOLES
WHEN FILLING MAKE SURE THAT BOTH OPENINGS ARE
POINTING UP AT THE SAME ANGLE
