XI. Machine Lubrication.
Lubricating the X-Y Rack and Pinion.
Lubrication is important with rack and
pinion gearing systems. A thin film of grease
should always be present on the contacting tooth
flanks to minimize metal to metal contact.
Lithium grease lubrication is recommend
over oil, as the oil lubrication will flow away from
tooth flanks.
The grease should be applied to the rails
at regular intervals, depending on the usage of the
machine. Use a small brush to coat both rails on
the side of the Y-axis and the single rail across the
X-axis.
Lubricating the X-Y-Z Rails
The rail carriage bearings are sealed and protected
with wipers. The rails should be lightly oiled to allow smooth
operation. Avoid a build up of debris on the rails by blowing
them off with air, or wiping them down with a rag. The rails
do not need to be lubricated as often as the rack, once a
month should be sufficient.
X Axis Z Axis Y Axis
Lubricating Z Ballscrew
The Z axis uses a ballscrew and
ballnut instead of a Rack and Pinion. You
must apply oil directly to the ballscrew to
properly lubricate the mechanism.
Lithium grease is pumped into the
lubrication point with the application gun.
Recommended Lubricants.
Lithium Based Grease:
Alvania Grease No. 2(Shell)
or Equivalent.
Techno Part No.

NOTE: AVOID A BUILD UP OF DEBRIS ON
MOVING PARTS. CLEAN OFF ANY DEBRIS TO
AVOID DAMAGING THE MACHINE.
