VI. HD Machine Lubrication.
5.1 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. Fig 5.1
Fig 5.1
5.2 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.

5.3 Lubricating Z Ballscrew
The Z axis uses a ballscrew and ballnut instead
of a Rack and Pinion. The ballnut has a nipple for
applying lubrication to the mechanism. Fig 5.3a
