5. &. To maintain the chuck for a long period of time, it is., necessary to lubricate the chuck on a regular basis. Inadequate lubrication causes malfunction at low hydraulic pressure, reduces gripping force and effects gripping accuracy, and causes wear and seizure.. Section to be lubricated Lubrication cycle. 1,,. Grease to the nipple at the circumference of chuck body with a grease gun. Once a week. However, when the machine is operated at high speed rotation or a large amount of water soluble cutting oil is used, more of lubrication is needed according to service conditions.

6.. If there are chuck malfunctions, stop the lathe and try the following countermeasures. Nonconformity Cause Action. Chuck parts are damaged.. Disassemble and change.. Chuck does not work.. Slide parts are seized.,. Disassemble and remove seized portion and make repair or change.. Rotating hydraulic cylinder does not work.. Examine the hydraulic system. Insufficient Chuck jaw stroke.. Chips are deposited in the chuck in large amount.. Drawbar is slack.. Disassemble and clean up the parts.. Remove the drawbar and retighten.. Work piece slips.. The jaw stroke is insufficient.. Make sure the jaw are located in the stroke center, when clamping a work piece.

Nonconformity Cause Action. Clamping force is insufficient.. Top jaw dia. does not match work piece dia.. Confirm whether the hydraulic pressure is sufficient.,. Check the status of the top jaw and change it. Poor accuracy.. Cutting force is too high.. Oil for the jaw and each slide part is run out.. Calculate cutting force and reduce it up to chuck specifications.,. Lubricate grease and operate jaws repeatedly without a work piece.. Speed is extremely high.. Reduce speed to a level where necessary clamping force can be obtained.. The periphery of the chuck is trouble.. Confirm peripheral and end surface run-out then tighten bolts.

Nonconformity Cause Action Poor accuracy.. Clamping force is so strong as to dent a work piece.. Reduce clamping force in accordance with specifications to prevent deformation of a work piece.
