Your lathe chuck is really a consumable. It wears with use. In addition, chuck wear results primarily from lack of lubrication and improper usage and application. Burrs, coolant, chips, poor chucking practice all contribute to the problem. These can be overcome to a large extent by proper maintenance and lubrication. Poorly lubricated chucks wear out faster and become unsafe for use. Chucks can easily lose 50% of their normal gripping force and accuracy if not properly lubricated.
Recommended Grease
All GMT Chucks are factory lubricated with GMT recommended grease and
are ready to use.GMT chucks are provided with dust cover for better
protection.
Under clean operating conditions, GMT chucks can be operated up to 10,000 cycles without dismantling & re-lubrication. To ensure extended service life and maximum performance ,every chuck should be dismantled ,cleaned and re-lubricated periodically.
Dismantling Frequency:
A new chuck must be dismantled after completion of 10,000 cycles.Then periodically after completion of every 20,000 to 25,000 cycles. If C.I castings are machined continuously , dismount once in a month regardless of no. of cycles. While applying grease by grease gun, slide the master jaw through full stroke (clamping and de-clamping) to ensure uniform distribution of grease on sliding surfaces.
Important Tip : The life of the chuck is considerably extended when it is well lubricated.

Frequency schedule for lubrication
Because of the widely differing job conditions, it is difficult to recommend a standard frequency schedule for lubrication. Lubrication once per shift with grease gun can be taken as a general standard norm. Recommended Grease
