Main Types of CNC Machine Covers

Aug. 06, 2025

In modern CNC machining environments, chips, coolant, and dust can cause significant long-term damage to guideways, ball screws, and other critical components. Choosing the right machine cover (way cover) not only extends the service life of equipment but also ensures high precision and efficiency. This article introduces the main types of CNC machine covers and highlights how LIONSHELL’s innovative products address diverse application requirements.


Overview of Common CNC Machine Cover Types


Based on industry standards and market practices, the most common CNC machine covers include:


1. Fabric Bellows


Highly flexible, suitable for high-speed movement and long strokes, often made of coated fabrics, thermoplastics, or aramid fibers.


2. Fabric Roller Shutters


Designed for fast extension and retraction, suitable for long travel paths with limited installation space.


3. Steel Flat Covers (Skateboard Covers)


Rugged and durable, ideal for environments with heavy chips, welding sparks, and high temperatures.


4. Aluminum Roll-up Curtains


Made from linked extruded aluminum plates, offering effective shielding against hot chips, oil, and coolant.


5. Metal-Shielded Bellows


Combines fabric bellows with protective metal elements for enhanced resistance to chips and liquids.


6. Metal Roll-up Covers (Steel Band Shutters)


Suitable for long travel distances, can withstand foot traffic for inspection and maintenance.


7. Steel Telescopic Covers


Provide the highest level of protection for machine guideways, shielding against chips, tools, and chemicals, while remaining repairable and replaceable.
