FOR SAFE OPERATION -23-
SO-NL-B9E/O
11.
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.)
12.
When setting the coordinate system using the machine coordinate system setting
function, any mistake in specifying the X and Z values in the G50 block will cause
interference between the cutting tool, tool holder, or turret head, and the
workpiece, chuck, fixture, or tailstock (if featured), damage to the machine, or will
cause the cutting tool failing to reach the cutting position.
13.
Support the workpiece securely before stepping on the chuck clamp/unclamp
footswitch to remove it. If you step on the footswitch without taking this
precaution the workpiece will fall and this could cause damage to the machine.
14.
You will probably use a variety of workpiece shapes and materials, and the
chucking method will differ according to the workpiece type. Therefore, when
checking a program with the workpiece clamped in the chuck, check for
interference carefully, taking the workpiece shape and material, and the chuck
gripping force, into account. Depending on these factors, the cutting tool, holder,
or turret head might interfere with the workpiece, chuck, fixture, or tailstock (if
featured), causing damage to the machine.
15.
If the workpiece is supported using the tailstock spindle, carelessly moving the
tailstock spindle in or retracting the tailstock body will leave the workpiece held by
the chuck alone. The workpiece may fall, causing damage to the machine, if it is
held only by the chuck. Therefore, before moving the tailstock spindle in or
retracting the tailstock body, ensure that the workpiece is held securely by a
crane or other appropriate means. (Applies only to machines equipped with a
tailstock.)
16.
Mount cutting tools to the turret head in a well-balanced manner, and ensure that
there will be no interference between the cutting tools/holders and the workpiece
or machine. If a cutting tool projects too far it will interfere with the Z-axis
protector, tailstock (if featured), or workpiece, etc., when the turret head is
rotated, causing damage to the machine.
17.
Whenever mounting or removing a tool to or from a rotary tool holder, remove the
rotary tool holder from the turret head and mount or remove a tool to or from the
rotary tool holder outside the machine. If a tool is mounted or removed to or from
the rotary tool holder mounted in the turret head, it could cause damage to the
machine. (Applies only to milling specification.)
18.
When mounting a tool to a rotary tool holder using a collet, do not tighten the
collet clamping nut excessively. If the collet clamping nut is tightened
excessively, the nut will be damaged, which causes the tool and the machine to
be damaged. (Applies only to milling specification.)
