A CNC oscillating knife machine cuts and grooves polyester fiber PET felt by using a high‑frequency vibrating blade and special slotting tools, all controlled by digital drawings on a vacuum table that keeps every panel accurate and consistent. Once the panel is fixed, the machine follows your CAD file step by step to complete both cutting and V‑grooving in an automated workflow.
First, place the polyester fiber PET felt panel on the working table of the PET felt cutting machine. The table is a vacuum adsorption table, which firmly holds the panel during cutting to prevent movement that could damage the material or affect accuracy.
When the vacuum is on, the panel stays flat and stable, so even long cuts and detailed shapes remain aligned with the design.
Next, select the appropriate blade according to the cutting shape and the thickness of the PET felt. Install the blade on the cutting tool holder, making sure it is fixed securely to avoid shaking or offset in the cutting process.
If the job also needs grooves (slots or V‑grooves), prepare the special slotting tool and mount it on the machine as required.
On the control panel of the polyester cutting machine, set parameters such as cutting speed, cutting depth, and, for slotting, groove depth and angle. These settings are based on the material type, thickness, and the specific design you are processing.
Correct parameters help you get clean cuts and grooves without over‑cutting the panel or leaving uncut fibers.
Start the polyester fiber cutting machine and let it cut the PET felt along the paths defined by the CAD drawing. During cutting, the oscillating knife moves up and down at high frequency while the CNC system drives it in X‑Y, so complex shapes, curves, and small details can be completed automatically.
Keep the cutting tool properly fixed and check occasionally that there is no abnormal vibration, to maintain stable accuracy throughout the job.
If grooves are required, install the slotting tool (for example, a V‑cut or dedicated grooving tool) on the PET felt cutting machine. Set the slotting depth and angle according to the design, then let the machine run along the positions where grooves are drawn in the file.
The slotting tool creates straight or angled grooves so panels can be folded, joined, or shaped while keeping the visible surfaces neat and functional.
After cutting and slotting are finished, move the cutting head to a safe position at the rear of the machine. Collect the finished PET felt pieces and clear any small debris from the worktable so the vacuum surface stays clean for the next job.
Good housekeeping around the cutting area also helps maintain vacuum performance and overall cutting quality over time.
To protect the acoustic felt cutting machine, reduce wear on accessories, and ensure operator safety, it is important to carefully study and follow the operating procedures and precautions provided by the supplier. Jinan Shilai Technology Equipment Co., Ltd. (SLCNC) offers detailed guidance and support as a leading manufacturer of intelligent CNC oscillating knife cutting machines and digital flatbed cutting solutions.
If you are working with PET felt acoustic panels and want to upgrade from manual cutting to digital processing, you can contact SLCNC to request a quote or full catalog and discuss a configuration that fits your panel sizes, groove designs, and production goals.
