“Clean Up Dust Occasionaly”
Yes. We know it is misspelled. This is a sticker we found while servicing the rack and pinion system of a Heian Router. We thought we should add another sticker that said “When you feel like it or the boss is watching.”
While the rack in pinion systems are less accurate than ball screw systems, they make up for lower accuracy with increased speed and reliability. However, even with this simpler design, the gear teeth and rack track need to be cleaned and scrubbed periodically as preventative maintenance.
Y-Axis End Mounts
Ball screw tension is set on the Y-Axis by two fixed end mounts. While it may seem that the almost 3” wide solid steel shaft of the screw is stout, it does have a considerable amount of flex. For a ball screw to be effective, it must be stretched between the two mounts.
Note the dust covering the ball screw shaft before service. That dust is being packed inside the ball nut and has been doing so for years.
