The instructions for carrying out ordinary maintenance on the machine mechanical parts are set out below.
This type of maintenance is important to preserve the integrity of the parts that determine the precision
and movement of the laser. These operations must be carried out at regular intervals since it is important
to check the state of wear and tear of the mechanical parts and the integrity of the machine in general
periodically.
GREASING THE WORM SCREW
In order to prevent malfunctions and potential mechanical faults, make sure that the worm screw, which is
located inside the column (figure 65), is always well greased so as to guarantee the precision and fluidity
of the movements. We recommend using a mineral oil-based, water repellent infusible grease, thickened
with NLGI 2 grade bentonite. Next, position the Z axis at its lower limit, remove the safety guard in order
to access the inside of the column, eliminate the old grease from the worm screw using a cloth and clean
it thoroughly. Once the old grease has been removed, use a brush to apply the new grease along the
entire length of the screw; avoid using excessive quantities of grease as this could compromise the correct
operation of the machine. After applying the grease on the screw, position the Z axis at its upper limit and
then return it to the lower limit; repeat this operation twice to distribute the grease evenly over the entire
length of the screw.

TROUBLESHOOTING, FAULTS AND MAINTENANCE
MAINTENANCE ON LINEAR GUIDES
To ensure the axes function correctly and run smoothly on the guides, we recommend cleaning the
latter with a dry cloth, removing the dirt while taking care not to scratch the guides. Once cleaned, use a
clean cloth to oil the guides, taking care not to apply excessive lubricant. Excess lubricant on the guides
could cause further damage if it is transferred to electric cables or other electrical parts. We recommend
inspecting the guides frequently and cleaning them whenever necessary.
The guides to be oiled are those highlighted in red in the figures below (figures 66-67-68-69). We
recommend using synthetic CLP, CGLP (according to DIN 51517) or HLP (according to DIN 51524) type
oil having a viscosity between ISO VG32-100 for working temperatures between 0° C and +70° C. We
recommend ISO VG10 for use in environments with lower temperatures. Be very careful NOT TO OIL the
magnetic strip on the Y axis highlighted in green (figure 66).
