FOR SAFE OPERATION -35-
SO-NL-B17E/O
1.
Before starting mass production, always check the program and perform test
cutting in the single block mode. If you fail to do this the workpiece could collide
with the cutting tool during machining, causing damage to the machine.
Machining defects could also be caused.
2.
In the case of machines that feature a hard-overtravel function, when a hard-
overtravel alarm has occurred, the interlock axis movement interlock can be
released by pressing the 2nd O.T. release button. Be very careful not to move
the axis in the wrong direction after pressing this button. If the axis is fed further
in the direction in which hard overtravel occurred, the turret head and carriage
may collide with the covers, causing damage to the machine. For the sake of
safety, feed the axes using handle feed (
×
1) until the hard-overtravel alarm has
been cleared.
3.
Be aware that the program will be executed at an unexpected feedrate if the dry
run function is made valid mistakenly during automatic operation, and this could
cause damage to the machine.
4.
When the EMERGENCY STOP button or reset key has been pressed to stop the
machine during a threading operation or a hole machining operation, especially a
tapping operation, carefully feed the axes after checking the workpiece and
cutting tool carefully for damage. If you feed the axes without due care, the
workpiece and cutting tool may collide or interfere with each other, and this could
cause damage to the machine.
5.
Keep the chip conveyor operating all the time during automatic operation. If
chips accumulate on the conveyor it will not be possible to expel them and the
chip conveyor could be damaged. (Applies only to machines equipped with a
chip conveyor.)
6.
Do not press the reset key during background editing since automatic operation
will be reset and the machine will stop suddenly: this could cause damage to the
machine.
7.
Before positioning the saddle to join it with the tailstock, first retract the X-axis in
the positive direction so that the turret head and other machine elements will not
interfere with the tailstock when the saddle is moved to the joint position.
Interference could cause damage to the machine. (Applies only to machines with
a programmable tailstock.)
8.
Check that no abnormal noise or vibration is generated during machine
operation. If there is any abnormal noise or vibration, determine the cause and
take appropriate action.
Continuing to operate the machine without taking any action could cause
machine faults. It will also adversely affect machining accuracy.
9.
Never move the axes or rotate the turret head manually while the automatic
operation is temporarily stopped. If it becomes necessary to do these manually,
always return the axes or the turret to the previously located position before
restarting the automatic operation.
If the automatic operation is restarted after indexing other tool or without returning
to the previous position, a tool may be hit against the workpiece or the chuck, or
other problem may occur, causing damage to the machine.
