Installation – fixed system
Installing a fixed system
When installing the fixed system, refer to the
figure on page 22.
WARNING: Before starting to install the
NC4 system, ensure the machine is safe
to work on. Switch off machine power when
working in the control cabinet.
1. Mount the system in a position where air
can exit freely from the MicroHoles in the
access panels.
Do not mount the system in a position
where excessive quantities of swarf can
build-up.
2. Secure the adjuster pack to the machine
table using a securing screw. Align the pack
so it is approximately parallel to the machine
axis.
Use a dial test indicator to determine the
squareness of the adjuster pack relative to
the machine axis. The top and sides of the
pack should be within 1 mm (0.039 in) over
the length of the pack.
3. Lay the conduit in the machine to check the
length. Cut to length if necessary.
4. Before routing the air pipes, fit a Ø3 mm-to-
Ø4 mm straight adaptor pneumatic fitting
and a Ø4 mm blanking plug to the free end
of each Ø3 mm air pipe (refer to the figure
on page 22). This prevents the ingress of
debris into the air pipes.
5. Feed the two cables and air pipes through
the conduit. Do not apply excessive force to
the cables or air pipes as this could damage
the supplies or NC4. Apply an appropriate
lubricant if necessary.
6. Push the conduit insert into the end of the
conduit. Push the conduit into the gland and
tighten the gland nut to secure the conduit.
