Spindle Switches [SPINDLE]
The SPINDLE switches are used to start and stop the
spindle manually.
The spindle or the rotary tool spindle (MC type) is
manually rotated to cut the rough surface of a workpiece
or check workpiece run out.
For the condition for spindle starting, refer to page B-31 (7-1).
1.
Switch operation is impossible with the PANEL key-switch placed in the
(OFF)
position.
2.
Close the front door before pressing these switches.
WARNING
1.
Before starting the spindle, carefully check the workpiece chucking
conditions, the chucking pressure, and the spindle speed. If spindle
rotation is started when the workpiece is grasped unstably or when
the chucking pressure or spindle speed is inappropriate, the
workpiece could fly out, causing serious injuries or damage to the
machine.
2.
Be aware that the spindle will start rotating if the
(NOR),
(REV) or
(SPJ) switch is pressed by mistake while a manual
mode is selected and the conditions for spindle rotation are
satisfied. If these switches are pressed carelessly the spindle will
start rotating unexpectedly and this could cause accidents involving
serious injuries or damage to the machine.
