How to disassemble, assemble, and lubricate a CNC chuck

CNC chucks are relatively easy to disassemble and quite robust; beginners can disassemble them while following instructions.

First, locate the screws on the back and remove them. Use a wooden or copper stick to hammer from the front until the disc inside the chuck can be removed. Then, remove the small chuck inside, which serves for positioning and dust protection. Next, disassemble the corresponding position on the chuck side, remove the flat-head screws, and carefully remove the flat rectangular threaded disc. Finally, disassemble the digital chuck.

Clean the internal flat rectangular threads thoroughly, hammer them with a wooden stick, install the bevel gear shaft (also needing to clean the dirt between the teeth), and tighten the fixing screws. When installing the small and large chucks on the back, carefully check the contact surfaces for any bumps or scratches. Pay close attention to the chuck's precision, carefully smooth it with a file, and tighten the screws. You're done.
