A bellow cover in CNC (also known as a way cover or telescopic cover) is a protective component used to shield the moving parts of a CNC machine from harmful contaminants like metal chips, dust, coolant, and debris.
🔧 What Does a CNC Bellow Cover Do?
It acts like a flexible, expandable “accordion” that:
-
Expands and contracts as machine parts move
-
Covers linear guideways, ball screws, or slideways
-
Prevents debris from entering critical motion components
-
Helps extend machine lifespan and reduce maintenance
