How to properly lubricate a chuck?

In order to ensure that the lathe chuck can still maintain good accuracy after long-term use, lubrication becomes particularly important. Incorrect or inappropriate lubrication will lead to abnormal function at low pressure, weakened clamping force, poor clamping accuracy, abnormal wear and jamming, etc., so the chuck must be lubricated correctly.

First, apply molybdenum disulfide grease (black in color) at least once a day, and drive the grease into the chuck oil nozzle until the grease overflows the jaw surface or the inner hole of the chuck (the inner hole protective sleeve and the connecting nut). However, if the chuck rotates at a high speed or a large amount of water-based cutting oil is used for processing, more lubrication is required, which must be determined according to different situations. Secondly, be sure to use an air gun or similar tool to clean the chuck body and slide surface at the end of the operation. What you need to do next is to remove the chuck, disassemble it and clean it at least every 6 months. Keep the sliding surface of the clamp jaw clean and lubricated to extend the life of the chuck. And use anti-rust cutting oil to prevent rust inside the chuck, preventing the chuck from rusting and reducing the clamping force, making it impossible to clamp the workpiece.

Equipped with a suitable chuck, the CNC machine tool will be even more powerful. When selecting, manufacturers must tailor their selection according to the actual situation of their own products, so that they can play a better role.
