CHECKING THE FINAL CONCENTRICITY
OF THE COLLET CLOSING TAPER
Locate the probe to touch the inside closing taper of the body to
verify concentricity. Remove the body and clean the surfaces of
the spindle adapter and the body again before remounting. Check
the concentricity again and repeat this step until the desired
reading is met. Concentricity may be affected if using stock beyond
the nominal gripping range.
CLEANING AND MAINTENANCE
The spindle, collet head and the spindle mount mating surfaces
must be cleaned and free of chips and sludge whenever mounting
to the spindle or changing out a collet head. Visually inspect
collets for tearing or separation of rubber on a regular basis
during long job runs and during setup. If you are using a high
pressure coolant in your machining processes, you need to inspect
the collets more frequently. Do NOT clean an open spindle with
an air hose as chips and sludge may be forced into the spindle
drawbar area. Clean and lubricate all moving parts with Chevron
Ultra-Duty EP NLGI 2, Dow Corning BR-2-Plus, or Kluber
ALTEMP Q NB 50 grease. Store all unused products properly
to prevent corrosion and keep free of dust and environmental
particles.
Check to see that all mounting screws are in good condition
and replace when worn. All components must be replaced with
original Hardinge replacement parts.
INSTALLING A COLLET HEAD
Installing or changing of the collet head is possible only when the
chuck is in the unclamped position. Prior to inserting the collet
head you must clean the taper of the collet seat and the mating
taper of the collet head.
Fully insert the pins of the manual wrench into the holes in the
face of the collet head. Actuate or pull the lever to collapse the
segments before inserting it into the collet seat. Insert applying
light pressure. Orient the keyway in the collet head with the key in
the collet seat. To release the collet head from the manual wrench
you must press on the release button.
CAUTION
When actuating the manual wrench never reach inside the moving
parts where there is risk of injury to your hand. Clean and lightly
oil the collet head and the body before installing.
REMOVING OR CHANGING THE WORK STOP
Follow the previous instructions to remove the collet head before
changing the work stop. The collet head must be in the unclamp
position. Reach in and remove the seal and set it aside.
To remove the work stop you must turn the 3 pipe plugs
counterclockwise to remove them. Loosen the 3 set screws
counterclockwise 2 full turns. Grasp the stop rod and pull
forward.
Make any adjustments for the next job and insert the work stop
using the rod. Now carefully tighten the 3 set screws clockwise
until you feel resistance. Hand tightening is sufficient,
DO NOT
over tighten. Applying to much pressure can damage the set
screws. If you are not using the worktop, remove the 3 set screws
and insert the 3 pipe plugs. Remember to replace the seal before
inserting you collet head. Failure to use the seal may cause
malfunction of the collet system.
