Clean Gantry Rails

Introduction

Dust and debris can accumulate on the gantry rails, which run along the length of the table. The bearings that run on the rails are equipped with shields that are designed to keep debris from entering the bearing housing. After a period of time and use, debris can accumulate on the outside of the bearing shields as the gantry travels along the table.

About this task

If you notice any dirt or ink on the gantry rails, or an accumulation of debris on the grey rail bearing shields, clean them immediately with a Poly-Wipe lint-free cloth.

NOTE

Gently wipe dirt or debris from the gantry rails or bearing shields to avoid removing the lubricating grease.

IMPORTANT

In the event of an ink spill on the rail, it should be cleaned immediately, before the bearings have a chance to run over the spill. After the area has been cleaned, wipe the spill area again thoroughly with a water-moistened lint-free cloth to remove any chemical residue before running the gantry over the area again. Slight ink stains that remain on the rail after cleaning are not a major problem.

Procedure

  1. Open the Maintenance Station cover to ensure that there is no possible gantry or carriage movement.
  2. Use a dry lint-free cloth to remove any visible debris that has accumulated next to the runner bearing shields. It is only necessary to clean the outside bearing shields. When removing debris always wipe away from the shields so you don't push dust into the bearing block.
  3. Wipe any debris from the gantry rails. Do this gently so that you do not remove the grease that lubricates the bearings as they move along the rails.
  4. Close the Maintenance Station cover.
