WARNING!
The greater distance above the chuck surface that clamping occurs, the lower the
clamping force will be.
3.11.9 Notes on instruction of operating personnel
We recommend that the business operating our manual chucks makes the operating instruc-
tions in particular thesection "Safety" available to all persons being in charge of operation,
maintenance and repair, with the intention ofacquiring specialised knowledge. We further rec-
ommend that the business operator issues internal "operating instructions" which take into
account the known qualifications of the operating personnel.
The business operator must guarantee that suitable measures in organisation and instruction
are taken to ensure that the appropriate safety rules and regulations are complied with by the
persons entrusted with operation, aintenance and repair of the manual chuck.
3.11.10 Lubricating and cleaning the lathe chuck
ATTENTION!
Do not use compressed air to remove dust and foreign substances from the lathe chuck.
Coolant squirts on the lathe chuck and removes the grease from the master jaws. In order to
maintain the tensioning force and the long-term accuracy of the lathe chuck, the lathe chuck
must be lubricated regularly. Insufficient lubrication will result in malfunctions at reduced ten-
sioning force, which affects the accuracy and causes excessive wear and seizing.
Depending on the chuck type and operating state, the tensioning force of a lathe chuck can
decrease by up to 50 percent of the nominal tensioning force.
A presumably securely clamped workpiece can then fall out of the chuck during processing.
Oil the chuck regularly at the oiler. Use additional an lubricant on the toothing of the clamping
jaws, which is of high quality and for high pressure bearing surfaces. The lubricant should with-
stand the coolant and other chemicals.
