Way Cover - How it Works and Troubleshooting Guide

The Way Covers are Rusty or make Excessive Noise

Symptom: The way covers are rusty or make
excessive noise.
Possible Cause: The coolant concentration is low.
Way cover movement during dry machine operation
creates friction. The rail bolts are loose.
Corrective Action:
When the machine operates normally, way covers
are lubricated by the coolant. It is critical to
maintain the correct coolant concentration. For
instructions, refer to the link for STANDARD
COOLANT – MAINTAINING YOUR COOLANT
MIXTURE
Dry machining: If you cut parts without flood
coolant, make sure that you lubricate all of the way
covers with lightweight oil. Fully extend the way
cover. Spray an even coat of lightweight oil on the
way cover.
The way covers slide on the rails that are attached
to the casting. If you lubricate the way cover on the
outside, and it still makes noise, apply grease to the
rails.
The way cover rails are loose: Tighten loose rail
bolts.
If the bolts [1] that hold the way cover rails to the
casting are loose, the way covers make "popping"
noises when they move. This eventually damages
the plastic tabs [2] that slide on the rails. This
causes sections of the way cover to separate and
to leak coolant.
As soon as the way covers start to make "popping"
noises, inspect the rails for loose screws. Tighten
the loose screws to prevent damage to the tabs.
