-22- FOR SAFE OPERATION
SO-NL-B17E/O
1.
If no tool holders for rotary tools are mounted in the turret head, fit covers to the
rotary tool holder mounting holes after checking that the covers are fitted with O
rings. If covers are not fitted, chips and coolant will get inside the turret head and
may cause machine faults. (Applies to milling specification.)
2.
Keep the machine light on during setup to ensure safety. If this light is off it will
not be possible to check conditions inside the machine or test cutting properly,
and this may cause damage to the machine or machining defects. In addition,
operators could be injured while working inside the machine.
3.
If the machine is stopped for a day or longer, the oil film on the slideways may be
lost. If the machine is started in this condition the slideways and ball screws will
be worn and might seize.
Therefore, if the machine has not been operated for a day or longer, press the
manual lubrication pushbutton to forcibly lubricate the slideways.
4.
Do not stop spindle rotation while the cutting tool is in contact with the workpiece.
This will cause damage to the tool and/or machine.
5.
Do not turn the manual pulse generator dial any faster than 5 rotations per
second. If you do, the axis will not stop immediately when the manual pulse
generator is stopped and the actual amount of axis feed will not coincide with the
number of pulses generated. This could cause damage to the machine.
6.
When the turret head is rotated with cutting tools mounted in it, tools with long
projection lengths could strike the Z-axis protector (cover or tailstock), etc.
Before rotating the turret, make sure that the tools in the turret do not interfere
with the protector (cover or tailstock), since interference will cause damage to the
machine.
7.
When mounting an I.D. cutting tool in the turret head, make sure that the tool
shank does not project beyond the rear surface of the tool holder. If it does it will
interfere with the turret base, etc., during turret head rotation, causing damage to
the machine.
8.
Remember that the direction of spindle rotation is determined by the tool
registration data and the spindle will rotate in the wrong direction if the settings
are incorrect. Machining while the tool is rotating in the wrong direction can
cause damage to the tool and the machine. (Applies only to milling specification.)
9.
When shifting the coordinate system in order to check a center-work program, set
the shift direction and shift amount carefully to avoid interference between the
turret and tailstock, which could cause damage to the machine. (Applies only to
machines equipped with a tailstock.)
10.
An extraction bar used when removing the center from the tailstock body is fitted
inside the tailstock of some models.
It functions for shock-proofing when another bar, inserted from the rear of the
tailstock body, is tapped to remove the center. It also serves to prevent chips and
coolant from entering the tailstock body during machining. Do not operate the
machine without the extraction bar fitted inside the tailstock body since this could
cause damage to the machine. (Applies only to machines equipped with a
tailstock.)
