CAUTION:
Make sure that the workpiece is adequately gripped so that the workpiece will not come loose
during the machining process. When clamping very short workpieces, the minimum clamping lengths must be observed.
They depend on the selected clamping head size and shape – call Hardinge for guidance. Do not clamp tapered work
pieces. In general the collet system should never be rotated without a clamped workpiece. Never rotate the collet
system over 2,000 RPM without a clamped workpiece. When actuating the changing wrench, never reach inside the
moving parts for risk of severely damaging your hand.
Drawbar Linkup
The Hardinge FlexC Collet System requires a drawbar linkup to mate the specific machine drawbar (varies by machine brand
and model) to the FlexC clamping sleeve. This linkup can be ordered from Hardinge or can be made by the customer.
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.
