Acoustic panels are essential components in managing sound quality in various environments, such as recording studios, offices, and home theaters. Cutting these panels accurately and efficiently requires the right tools and techniques, especially when dealing with materials like polyester fiber sound-absorbing panels, fiberglass boards, or rock wool boards. Here’s a detailed guide on using CNC oscillating knife cutting machines for this purpose.

Step 1: Select the Appropriate Cutting Tool
- Material Thickness and Type: Choose the cutting tool based on the thickness and type of material. For instance:
- Ordinary Oscillating Tool: Ideal for cutting polyester fiber panels ranging from 9mm to 12mm.
- Pneumatic Oscillating Tool: Suitable for thicker felt sound-absorbing panels, around 24-40mm.
- Bevel Cutting Tool: Best for creating V-grooves at various depths.

Step 2: Setup the Machine
- Tool Installation: Install the selected tool on the CNC machine.
- Parameter Settings: Adjust parameters such as cutting speed, oscillation rate, and depth based on material specifications to ensure precise cuts without damaging the material.

Step 3: Material Preparation
- Placement: Securely place the acoustic panel on the cutting table. If dealing with larger or more flexible panels, consider using a vacuum adsorption system to prevent any movement during cutting.
- Alignment: Ensure the panel is perfectly aligned with the cutting path set in the machine’s control software.

Step 4: Cutting Process
- Monitoring: Start the cutting process and monitor the operation. Adjustments may be needed on-the-fly if any discrepancies are observed.
- Multi-Tool Usage: If your design requires both cutting and grooving, use a dual tool holder setup. This configuration allows the simultaneous installation of an oscillating knife and a bevel tool, enabling cutting and grooving in one pass.
Step 5: Post-Processing
- Inspection and Cleaning: After cutting, inspect the edges and surfaces for any irregularities or burrs. Clean the cut panels using a soft brush or air gun to remove any debris.
- Finishing Touches: If necessary, perform any additional finishing, such as edge sanding or painting, to prepare the panels for installation.
Maintenance Tips
- Blade Care: Regularly check and replace blades to maintain cutting efficiency. Always ensure that the blade installed is sharp and correctly oriented.
- Machine Maintenance: Clean the tool holders and cutting area regularly to avoid dust buildup, which can affect machine performance and panel quality.
