REMOVING CHIPS ENTANGLING WORKPIECE
The procedure to follow to remove chips entangling a workpiece during machining is explained
below.
1)
Press the
(SP) switch to suspend program execution at a position where chips will be
removed from the workpiece easily.
2)
Select any of the following modes with the MODE selection switch.
(H),
(JOG),
(RPD),
(ZRN)
The spindle stops rotating when any of these modes is selected.
3)
Make sure that the DOOR INTERLOCK key-switch is placed in the
NORMAL
position.
4)
With the manual door type machine, press the DOOR UNLOCK switch
to unlock the
front door. Then open the front door.
With the automatic door type machine, open the front door by pressing the AUTOMATIC
DOOR OPEN switch.
5)
For center-work operation, make sure that the tailstock spindle interlock function is valid.
After that, press the
(TSI) switch to move the tailstock spindle into the tailstock.
If the tailstock spindle is retracted, the workpiece is held only by the chuck and the
workpiece may fall.
After the completion of the machining, make sure that the workpiece is supported not to
fall from the chuck if the tailstock spindle center retracts from the workpiece.
WARNING
1.
Always stop the machine before removing chips inside it during
operation. Also stop the machine and coolant supply before
adjusting the direction or volume of coolant supply. If you attempt
these operations while the machine is operating you could be
seriously injured by being entangled in the revolving parts of the
machine or crushed by its moving parts.
2.
Pressing the
(SP) switch during automatic operation stops axis
movement but does not stop spindle rotation. Therefore, select a
manual mode and confirm that spindle rotation has stopped before
opening the door. If you open the door while the spindle is rotating
you may be entangled with the spindle and seriously injured.
3.
Before opening the front door to remove chips from inside the
machine during machining operation, make sure that the door
interlock function is ON. After removing the chips, close the front
door before restarting machine operation.
If the door interlock function is invalid, it will be possible to open the
door while the machine is operating, and this could cause accidents
involving serious injuries or damage to the machine.
NOTE
CAUTION
