SETUP
1) Always make sure that the setup is complete.
2) After changing the setup, operate the machine step by step to make sure the cutting can be
conducted without problems.
3) Before replacing the chuck and/or chuck jaws, make sure that the new set fit the job in-
tended.
4) When two or more workers work as a group, establish the necessary safety signs, for ex-
ample, when lifting or setting heavy objects confirm with other workers whether or not it’s
“okay” to start the next process.
5) When handling heavy objects use a crane or equivalent tool.
6) When attempting unfamiliar setups check the setup again before going on to the next step.
WORKPIECE LOADING and UNLOADING
1) Load and unload workpieces securely.
2) Retract the turret before loading and unloading a workpiece to a position where the cutting
tools on the turret will not injure the operator’s hands.
3) Before attempting to load or unload a workpiece, make sure the spindle has come to a com-
plete stop.
4) Before running a new program, first rotate only the spindle to make sure the workpiece is
securely clamped in the chuck.
5) To machine irregularly shaped workpieces, make sure the workpiece is clamped in the chuck
securely without imbalance.
6) When handling heavy workpieces, use a crane, hoist, or other tool.
7) Before setting a workpiece in the machine, make sure the workpiece has portions that can be
used for proper chucking.
MACHINING CENTERS
1) Never touch the spindle or tool while the spindle is rotating.
2) Never touch the spindle or tool while the spindle is being oriented, or while it is changing
speed range. The spindle might rotate suddenly.
3) Never start spindle rotations with a tool or any other object mounted in the spindle in such a
way that it could easily come loose.
4) Always wait until the spindle has come to a dead stop before attempting to remove chips
from the tool.
5) Never begin operations without first checking that the workpiece has been securely mounted
on the table.
6) Never start table movements with anyone on the table.
7) The automatic tool changer and automatic pallet changer are particularly dangerous when
they are in operation and all personnel should be kept clear of their operation zone.
8) Inspection or changes of tools in the magazine of the ATC should be carried out only when
the ATC is in the manual operation mode.
9) If, for whatever reason, the ATC or APC should stop moving during an operation and it
should become necessary to inspect them without first cutting off power, always secure an
emergency escape zone and never touch the problem unit directly with your hands.
10) Never attempt to clean the machine or inspect it while it is operating. Always bring it to a
complete stop before conducting such operations.
