2.11 Safety regulations for spindle use and maintenance
Before starting the spindles turning, it is essential to:
•
Check that the tools have been fitted only after the spindle seat has been cleaned.
•
Check that the tools are clamped tightly.
•
Make sure that the number of programmed revolutions is less than the maximum number of
revolutions permitted for the tools fitted on the heads.
•
Make sure that the size and weight of the tolls and the number of programmed revolutions is
compatible with the spindle power characteristics.
•
Make sure that the direction of rotation is the proper direction of the tools fitted on the heads
during machining.
•
If one spindle must turn in the opposite direction with respect to the standard rotation, check that
the safety ring-nut (or other appropriate safety devices) is present and tight.
•
If there is an all-around enclosure or cabin, make sure that the doors are closed and that none is
standing inside the enclosure.
•
Check the conditions of the tools and make sure that they are not chipped or deformed.
•
Make sure that the tools, spacers and tool holding shafts meet the specifications contained in the
machine instructions.
Before bringing the spindle to the programmed revolving speed, start the spindle turning slowly and
check (by listening to the noise) that the tools are balanced and do not vibrate excessively.
Before stopping spindle rotation during machining, make sure that the tool is not in contact with the piece
and/or parts of the template.
2.12 Safety regulations for use and maintenance of mechanical
components
Do not remove the safety guards (panels and gates) except for ordinary and extraordinary maintenance.
Never start-up the machine when the guards are not in place.
Do not touch moving or rotating parts.
Do not carry out maintenance or cleaning while the machine is running.
Do not enable any machine movement if someone is inside the enclosure.
Do not enable blocking devices if someone is inside the enclosure.
