As demand for comfortable and acoustically optimized spaces continues to grow, sound-absorbing materials are increasingly used in offices, conference rooms, recording studios, cinemas, schools, hotels, restaurants, and residential interiors. A CNC sound-absorbing board cutting machine provides manufacturers with a fast and flexible solution for both standard and customized acoustic panel production.

Sound-Absorbing Board Cutting Machine
A sound-absorbing board cutting machine is a professional CNC cutting system designed to accurately process acoustic panels, soundproofing boards, PET felt, polyester fiber panels, fiberglass boards, mineral wool boards, and other acoustic materials. With digital CNC control and high-precision knife cutting technology, it can produce clean, accurate shapes for modern acoustic wall and ceiling systems.
Oscillating Knife Cutting Machine for Sound-Absorbing Board
An oscillating knife cutting machine for sound-absorbing board is a professional CNC digital cutting solution designed specifically for processing acoustic panels, PET felt, polyester fiber sound-absorbing boards, acoustic foam, felt, and other soft or semi-rigid materials.

Unlike traditional saw cutting methods, an oscillating knife cutting machine uses a rapidly reciprocating blade to cut materials mechanically rather than thermally. This makes it particularly suitable for sound-absorbing board cutting, where clean edges, accurate dimensions, low dust generation, and flexible shape processing are important.
With CNC control, automatic nesting software, vacuum adsorption, and high-speed oscillating knife technology, the machine can produce straight lines, curves, holes, geometric patterns, letters, logos, and customized acoustic panel designs.
It is widely used in the production of acoustic wall panels, ceiling baffles, office partitions, recording studio panels, theater interiors, decorative acoustic panels, and customized architectural sound-absorbing products.

How Our Machines Are Used in the Sound‑Absorbing Board Industry
Cutting Acoustic Panels
Common materials: PET felt panels, polyester fiber sound‑absorbing boards, rock wool / mineral wool, and fiberglass wool.
Applications: Straight cutting, chamfering, grooving (V-groove, U-groove), and punching holes for installation.
Benefit: Smooth, burr-free edges that improve both aesthetics and acoustic performance.
Slotting & Beveling
Use our multi-tool system to perform slotting or bevel cutting in one pass, enabling seamless panel splicing or decorative design effects.
Precise angle cuts (e.g., 5°, 30°, 45°, 60°, 90°) are achievable, enabling more creative design and better acoustic joining.
High‑Efficiency Production & Nesting
Nesting software arranges parts intelligently to maximize material utilization—saving up to ~10% or more compared to manual layout.
Continuous cutting on vacuum or conveyor table ensures stable production for large batches of panels.
Safe & Dust‑Controlled Operation
Our cutting solutions eliminate the need for hot cutting, reducing risk of smoke or material burning.
Vacuum-hold or partitioned adsorption tables hold soft acoustic materials firmly, preventing deformation during cutting.
Infrared safety sensors and other protection devices ensure safer operation in busy production environments.

What Is an Oscillating Knife Cutting Machine?
An oscillating knife cutting machine is a CNC digital cutter equipped with a rapidly moving blade. During operation, the knife moves up and down at high frequency while the cutting head moves along the programmed CNC path.
The combination of high-frequency blade movement and precise CNC control allows the machine to cut soft and semi-rigid materials efficiently.
For sound-absorbing boards, this cutting method offers several important advantages:
- Clean cutting edges
- High dimensional accuracy
- Low heat generation
- No laser burning
- Less dust compared with sawing
- Flexible cutting shapes
- Excellent repeatability
- Digital production
The machine can process a digital drawing and automatically reproduce the design on acoustic materials.
Applications of Oscillating Knife Cutting Machine for Sound-Absorbing Board
Acoustic Wall Panel Production
Manufacturers can produce customized acoustic wall panels for commercial and residential interiors.
Typical applications include:
- Office walls
- Hotel interiors
- Meeting rooms
- Restaurants
- Schools
- Libraries
The machine can create both standard rectangular panels and complex decorative designs.
Acoustic Ceiling Panel and Baffle Cutting
Acoustic ceiling baffles often require precise dimensions and customized shapes.
The oscillating knife cutter can produce:
- Ceiling baffles
- Hanging acoustic panels
- Linear acoustic elements
- Decorative ceiling shapes
Office Acoustic Partition Manufacturing
PET felt and polyester fiber are frequently used to produce acoustic partitions.
The CNC cutter can create:
- Desk screens
- Freestanding partitions
- Privacy screens
- Modular acoustic dividers
Recording Studio Acoustic Panels
Recording studios require carefully designed acoustic treatment products.
The machine can manufacture customized:
- Sound absorption panels
- Acoustic wall shapes
- Decorative studio panels
- Acoustic foam components
Cinema and Theater Acoustic Products
Acoustic materials are widely used in:
- Cinemas
- Theaters
- Auditoriums
- Performance halls
CNC cutting allows manufacturers to produce panels matching architectural designs.
Oscillating Knife vs Laser Cutting for Acoustic Panels
An oscillating knife is particularly attractive for acoustic materials because it performs mechanical cutting rather than relying on concentrated heat.
| Feature | Oscillating Knife | Laser |
| Cutting Method | Mechanical | Thermal |
| Heat Generation | Very Low | High |
| Edge Burning | No typical laser burn | Possible depending on material |
| PET/Felt Applications | Excellent | Material-dependent |
| Dust | Low | Low |
| Complex Shapes | Excellent | Excellent |
| Material Flexibility | Very High | Material-dependent |
For manufacturers processing large quantities of PET felt and polyester fiber acoustic boards, knife cutting can provide an efficient alternative to thermal cutting.
How to Choose an Oscillating Knife Cutting Machine for Sound-Absorbing Board?
1. Confirm Material Type
Before purchasing, determine:
- PET felt thickness
- Polyester fiber density
- Board dimensions
- Material hardness
- Maximum cutting thickness
2. Choose the Working Area
The cutting table should be large enough for your standard acoustic boards.
Common applications include:
- Small acoustic panels
- Standard sheets
- Large-format wall panels
Customized table sizes may also be available.
3. Select the Correct Knife
Different materials may require different cutting tools.
Possible configurations include:
- Oscillating knife
- Pneumatic knife
- Drag knife
- Rotary knife
The oscillating knife is particularly suitable for thick and dense soft materials requiring powerful penetration.
4. Consider Automation
For higher production volumes, consider:
- Automatic feeding
- Automatic nesting
- Camera positioning
- Barcode recognition
- Automatic material handling
