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.
Lubricate the lathe chuck at the worm and at the lubricating nipple. Lubricate the lathe chuck at
least once per week. The used lubricant should be of high quality and provided for high pres-
sure bearing surfaces. The lubricant should withstand the coolant and other chemicals.
Numerous different lathe chucks are available on the market which distinguish themselves con-
siderably based on the lubricating method. Follow the operating instructions of the correspond-
ing lathe chuck manufacturer.
