Maintenance
A chuck can only achieve its maximum clamping force when its internal components are clean and well lubricated.
During operation, centrifugal force displaces and thins the lubricant inside the chuck, forcing it out over time. If the chuck is exposed to cutting fluid, this process happens even faster. If maintenance is not followed daily, the chuck will lose its internal lubrication and collect cutting fluid sludge, rust, and metal
A chuck with reduced clamping force has a much higher risk of losing its grip during operation and throwing the workpiece with deadly force.
Daily Maintenance
•Check/correct loose mounting bolts.
•Use a vacuum, rag, or brush to clean the chuck after use.
•Wipe down the outside of the chuck with a light machine oil or way oil.
Regular Lubrication
Recommended Lubricant
Chuck Grease | .............................. Bison |
(or Equiv. | |
Oil | South Bend Way Oil #SB1365 |
Lubricate the scroll thread and jaw slides regularly, using either chuck grease or way oil. To lubricate, remove and clean the jaws, clean chips off the scroll gear if necessary, then re- install the jaws and apply lubricant to the scroll gear and jaw sliding surfaces. Move the jaws in and out to distribute the lubricant.
Chuck grease provides superior lubrication and clamping force; its drawback is that chips easily stick to it and get drawn into the chuck, leading to binding and reduced clamping force.
Way oil is a good alternative lubricant to reduce the amount of chips that stick to the chuck;
its drawback is a reduction of clamping force, making it a poor choice for heavy clamping loads.
Chuck Service
Proper chuck service requires full disassembly, cleaning, and lubrication. Perform this service every six months, or more frequently if the chuck is exposed to dirty work environments, heavy workloads, or cutting fluid.
To avoid damage when servicing the chuck:
•Only clamp chuck parts in a vise equipped with soft jaws or wood/aluminum blocks.
•Never use an open flame on chuck parts!
•Never strike the chuck with a steel hammer. Instead use a brass hammer or soft mallet.
•Never apply force to stuck components if you are unsure about how they are fastened together. Refer to the instructions.
•When separating or removing mated components, do not attempt to pry or wedge them apart. Instead, patiently tap them at various locations with a brass hammer or mallet while rotating and pulling on them.
•If the scroll gear or retainer is stuck, soak parts in penetrating oil or solvent (overnight if needed) to break down grease suction, then carefully rotate, lift, and tap it loose.
