PREPARATION
19. Push the STOP button in, move the spindle
lever to the OFF position, then replace the
end gear cover.
20. Lift the chuck guard up—this will activate
the chuck guard safety switch. Reset the
STOP button and attempt to start spindle
rotation—the spindle should not start.
— If spindle rotation does start with the
chuck guard in the up position, the safety
switch is not operating correctly. This
safety feature must operate properly
before continuing operation. Press the
STOP button to turn the lathe OFF,
disconnect it from power, and call Tech
Support for help.
21. Re-start spindle rotation, use the cutting
fluid pump switch on the control panel to
start the pump, then open the valve. Verify
that the cutting fluid flows from the nozzle,
then turn the pump OFF.
Congratulations! The test run is complete.
Turn the lathe OFF and perform the following
Spindle Break-In procedure.
Spindle Break-In
Before subjecting the lathe to full loads, it
is essential to complete the spindle break-in
process as described below. This will ensure the
best results and maximum life of the precision
components inside the lathe.
The break-in procedure must be performed
in succession with the Test Run procedure
described in this manual, because many of the
test run steps prepare the lathe controls for the
break-in process.
Important: Do not perform the break-in
procedure independently from the Test Run
section—serious damage could occur to the lathe
if the controls are set differently than instructed
in that section.
Do not leave the lathe unattended during the
Spindle Break-In procedure. If your attention
is needed elsewhere during this procedure,
stop the lathe and restart the procedure later
from the beginning.
To perform the spindle break-in:
1. Successfully complete the Test Run
procedure beginning on Page 25.
2. Using the spindle speed range lever and the
spindle speed dial to run the machine at the
following speeds for 10 minutes each: 100,
250, 500, 1000, 1500, and 2000 RPM.
Note: If necessary, refer to Spindle Speed on
Page 48 for detailed instructions about
selecting and changing spindle speeds.
3. Use the foot brake to stop spindle rotation,
then run the spindle in reverse (spindle lever
in the up position) at a speed of 2000 RPM
for 10 minutes.
