.

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.

If there are chuck malfunctions, stop the lathe and try the following countermeasures.

Nonconformity

Cause

Action

.

Chuck does not work.

.

Chuck parts are damaged.

.

Disassemble and change.

.

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.

.

Disassemble and clean up the parts.

.

Drawbar is slack.

.

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

Poor accuracy.

.

Clamping force is insufficient.

.

Confirm whether the hydraulic pressure is

sufficient.

.

Top jaw dia. does not match work piece dia.

,

.

Check the status of the top jaw and change it.

.

Cutting force is too high.

.

Calculate cutting force and reduce it up to

chuck specifications.

.

Oil for the jaw and each slide part is run out.

,

.

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.
