Tormach 8L - 7.6 Lubricate the Machine

7.5 EXAMINE THE SPINDLE BELT
To extend the service life of the spindle belt, you must
regularly examine it for signs of damage or wear.
If the spindle belt is damaged, you must replace it with Spindle
Belt, 8L (PN 37832).
7.6 LUBRICATE THE MACHINE
To keep the machine operating properly, and to extend the
service life of the machine, you must verify that the slideway
surfaces and ball screws are receiving lubrication.
Regularly do the following:
l Clean the oil reservoir's cover and all exposed surfaces
surrounding the oil reservoir. Swarf or debris that enters
the oil reservoir can plug the small, internal passages of
the lubrication system.
Note: The strainer at the top of the oil reservoir
isn't a filter, and can't remove all types of
debris that may cause blockages.
l Examine all axes' slideway surfaces and ball screws to
determine if an oil film is present.
If there's not an oil film, examine the lubrication system
for blockages, broken fittings, or pinched oil lines.
l Examine the amount of available oil and, if necessary,
refill with new, high-quality ISOVG 68 grade Machine
Oil (PN31386).
7.6.1 About the Manual Oiler
The manual oiler operates with a plunger:
l
On the Pull Stroke The oiler pulls machine oil from the
oil reservoir.
l
On the Retract Stroke The oiler pushes machine oil
through the lubrication system.
The plunger is spring-loaded, and creates a light hydraulic
pressure sufficient to distribute the oil through the machine.
Do not push the plunger after you retract it.
When the machine is first powered on (and then after every
four hours of operation), retract the oiler's plunger and hold it
in the retracted position for two seconds. Then, release the
oiler's plunger.
Note: The plunger should move slowly from the
retracted position. If it doesn't, it could indicate a
malfunctioning oiler.
7.6.2 About the Automatic Oiler
The automatic oiler is powered whenever the machine is
powered on, and has the following default settings:
l Lubrication interval: 480 minutes (8 hours)
l Actuation time: 12 seconds
7.6.3 Lubrication System Reference
The machine's lubrication system distributes oil to the
following 10 points:
l Eight sliding surfaces
o
Four on the X-axis
o
Four on the Z-axis
l Two ball nuts
7.7 PREVENT RUST
Take proper care to protect all exposed iron and steel surfaces
on your machine. To reduce the possibility of rust, you must
regularly do the following:
l Clean all exterior surfaces with a mild cleaner.
l Only use flood coolant that is recommended for
machining (see "Cutting Fluid Reference" (on the
previous page)).
l Periodically test the coolant concentration, and adjust (if
necessary) to meet coolant manufacturer's
recommended concentration.
l Put LPS 3® (or similar rust inhibitor) on the machine
before installing any workholding or accessories.
l Only operate the machine in a temperature- and
humidity-controlled environment. Extreme changes in
temperature or humidity can create condensation on the
machine.
l Put LPS 3® (or similar rust inhibitor) on all exposed, non-
painted metal surfaces before leaving the machine
unused.
l Remove all workholding and accessories, and then check
for rust.
l If needed, reapply rust inhibitor before reinstalling
workholding or accessories.
