-34- FOR SAFE OPERATION
SO-NL-B17E/O
WARNING
14.
While the machine is temporarily stopped during machining - for
example when checking a program, performing test cutting, or
cleaning chips out of the machine - do not feed the axes or index the
turret head in manual operation. Or, if it is absolutely necessary to
do so, be sure to return the axes and turret to their original positions
before restarting the program. If machining is restarted without
returning them to their original positions, the turret will move in
unexpected directions, causing collisions between the cutting tools,
holders, or turret head and the workpiece, chuck, or tailstock (if
featured), which could cause serious operator injuries or damage
the machine. The workpiece could also be machined with the wrong
tool, and the cutting tool could be damaged.
15.
Before switching the machine lock function from "valid" to "invalid",
wait until one program operation cycle has been completed. After
switching from "valid" to "invalid", always execute a zero return
operation. Switching between "valid" and "invalid" during program
execution will create a discrepancy between the position designated
in the program and the actual machine position, which could cause
accidents involving serious injuries or damage to the machine.
16.
When carrying out unmanned operation over extended periods, or
machining using an inflammable coolant such as oil-based coolant
or an inflammable workpiece, there is a likelihood of fire to occur. If
a fire were to develop in the machine, it could cause accidents
involving serious injuries or damage to the machine.
Mori Seiki will not accept responsibility for the loss due to a fire.
Install automatic fire extinguishing equipment and operate the
machine using great caution for the prevention of fire.
17.
If the door interlock function is "released" while the single block
function is valid, it constitutes very danger situation since the door
is unlocked permitting the door to be opened even while the
machine is operating, independent of the DOOR UNLOCK switch
state (lock or unlock), the selected mode, or executed operation
(automatic operation and manual operation). If the necessary
operation requires work to be carried out with the door open while
the machine is operating, this work must be limited only to that
which is absolutely necessary and must be carried out very
carefully.
Work which is carried out with the door open while the machine is
operating will cause injuries due to the operator being entangled in
the rotating parts of the machine, crushed by its moving parts, being
struck by a workpiece or chuck jaws that have flown out of the
machine, or being splashed by chips and coolant.
