Introduction
When operating a CNC oscillating knife cutting machine, one of the most overlooked yet critical components is the felt mat, also known as the felt conveyor belt. This simple-looking accessory plays a decisive role in ensuring cutting accuracy, material stability, and the lifespan of your cutting blade.
In this article, we will explore everything you need to know about vibrating knife felt mats — their structure, function, selection guide, and how to maintain them for optimal performance.
What Is a CNC Oscillating Knife Felt Mat?
A felt mat (or cutting felt belt) is a high-density, wear-resistant layer installed on the cutting table or conveyor of CNC oscillating knife cutters.
Its main function is to:
- Hold the cutting material in place through vacuum adsorption
- Protect the blade from damage during high-frequency vibration
- Provide a stable, smooth cutting surface
These felt mats are widely used in cutting fabrics, leather, sponge, cardboard, automotive interiors, composite materials, and advertising foam boards.
Structure and Types of Felt Conveyor Belts
There are generally two types of felt belts used in CNC digital cutting machines:
1. Single-Sided Felt Conveyor Belt
- One side is a felt layer, and the other side is PVC base belt.
- Lightweight and affordable.
- Suitable for basic flatbed cutting tables or environments where felt thickness is not critical.
2. Double-Sided Felt Conveyor Belt
- Both sides covered with felt for better grip and cushioning.
- Provides higher friction, noise reduction, and bidirectional conveyance.
- Ideal for auto-feeding cutting systems and continuous production lines.

Key Features of High-Quality Felt Mats
When choosing a CNC cutting felt mat, quality directly affects cutting precision and equipment lifespan.
Here’s what to look for:
- Cut-resistant surface – withstands repeated knife vibration without tearing
- High tensile strength – resists stretching and deformation
- No fiber shedding – keeps the cutting surface clean
- Smooth joint & seamless bonding – ensures stable material feeding
- Uniform thickness – maintains consistent cutting depth
Applications of Felt Conveyor Belts
| Industry | Application Example |
|---|---|
| Textile & Apparel | Fabric pattern cutting, garment sample making |
| Leather Goods | Bags, shoes, and upholstery cutting |
| Automotive Interiors | Floor mats, insulation, dashboards |
| Packaging | Corrugated cardboard, foam board |
| Advertising & Signage | PVC, KT board, acrylic sheets |
| Electronics | Anti-static transport of delicate components |
How to Maintain Your Felt Mat
Regular maintenance can significantly extend the service life of the felt mat and improve cutting accuracy:
- Clean the surface regularly with compressed air or a soft brush.
- Avoid liquid cleaners that may damage the felt fiber.
- Replace worn sections before they become uneven.
- Keep the vacuum adsorption area clear for strong suction.
Why High-Quality Felt Mats Matter
A low-quality felt mat may cause:
- Uneven cutting depth
- Poor adsorption and material shifting
- Faster blade wear
- Reduced production efficiency
Investing in a durable, high-density felt mat ensures consistent cutting precision, longer machine lifespan, and smoother workflow — especially for continuous production environments.
