Lubrication
X&Y-Axis Linear Rails
Apply 2-3 drops of a light oil (such as 3-in-1 oil) on the rails and spread it out evenly.
X-Y-Z-Axis lead screws
A light lubrication of the X, Y and Z-Axis leadscrews should be performed periodically. At a minimum,
lubrication should be performed every 6 months, although if applications that produce large amounts of
debris are run (such as wood or plastic engraving), cleaning and lubrication should be performed more
often. Only use Teflon-free silicone spray on the leadscrews. DO NOT use any lubricant other than
Teflon-free silicone spray, as it may attract debris and create a buildup that can cause mechanical
failure.
NOTE: Place a paper towel underneath the leadscrews to prevent over spray as shown below.
Working in the lubricants
After completing this procedure and re-installing the carriage and top covers, the lubricants should be
worked in to the motion system for several minutes prior to using the machine. To move the motion
system, use the X,Y and Z Jog Buttons to move the carriage, table and spindle through their range of
motion and evenly distribute the lubricants.
What not to lubricate
Many of the bearings and assemblies in your engraving machine are sealed and/or coated using
special low-friction methods and should not be lubricated.
DO NOT attempt to lubricate the spindle or the spindle bearings. This will attract particles and dust,
which will build up between the shaft and sleeve and possibly prevent movement. If you suspect
lubrication problems, call your dealer/representative or the service department at Vision.
DO NOT oil the stepper drive motors. None of the motors on the Vision Express require lubrication.
Oiling the stepper motors can permanently damage them.
DO NOT use any type of grease product to lubricate this machine.
