Description
9-Function Grooving Edge Banding Machine with Pre-milling & Rounding (Model HE-468PRG)
Band, Trim, Round, and Groove in one single pass. The HYG HE-468PRG is the ultimate “All-in-One” solution for wardrobe and cabinet manufacturers. By integrating a specialized Bottom Grooving Unit into the workflow, this machine eliminates the need for a separate slotting station, saving floor space and labor.
Built on our longest 7100mm industrial chassis, the HE-468PRG handles the complete edge finishing process—from Pre-milling defects to Corner Rounding for safety, and finally Grooving for back panels—delivering a ready-to-assemble component instantly.
The “G” Advantage: Why Choose Inline Grooving?
1. Integrated Bottom Grooving Station
The standout feature of the HE-468PRG is the addition of a high-speed grooving saw after the scraping unit.
Application: It creates a precise slot along the bottom edge of the panel. This is essential for inserting back panels in wardrobes, drawer bottoms, or installing hidden LED light strips in modern cabinetry.
Efficiency: Instead of moving heavy panels to a CNC router or table saw for slotting, the HE-468PRG does it automatically during the banding cycle.
2. Massive 21KW Power for Heavy Cutting
Adding a grooving saw plus dual pre-milling motors requires immense energy. We engineered the HE-468PRG with a Total Power of 21 KW.
Performance: This is the highest power rating in our 468 series. It ensures that the grooving saw cuts through dense melamine or plywood smoothly without affecting the speed of the 15-23m/min conveyor track.
3. The 7.1-Meter Stability Standard
To accommodate 9 distinct processing stations, the machine body is extended to 7100 mm.
Trustworthiness: A longer bed isn’t just about fitting parts; it’s about isolating vibration. The grooving action (which creates significant force) is physically separated from the delicate Fine Trimming and Corner Rounding units, ensuring the final finish remains flawless.
The Optimized 9-Stage Workflow
The HE-468PRG executes the following sequence for maximum quality:
Pre-milling: Dual diamond cutters clean the panel edge.
Gluing & Pressing: Applies adhesive and presses the tape.
End Cutting: Precision flush cuts (Front/Rear).
Rough Trimming: Removes heavy tape excess.
Fine Trimming: Creates the edge radius.
Chamfering (Corner Rounding): Rounds vertical corners.
Bottom Grooving (The Upgrade): Cuts the back panel/LED slot (Sequence Updated).
Scraping: Smooths the PVC surface and removes any potential debris from grooving (Sequence Updated).
Buffing: Final polish for a high-gloss finish.

Pre-milling
The diamond pre-milling cutter mills off the corrugated traces and redundant burrs of the spiral trimming knife of the wood board, so that the board edge fits the edge band more closely, and the bonding is firmer and nicer.
Gluing and pressing
The glue line is slight and the edge band does not run off.
End Cutting
Fast and stable, without bumping the board.
Rough Trimming
The rough trimming knife removes excess edge banding strips to form rounded corners, making the trimming nicer.
Fine Trimming
Fine trimming is to repair the board more carefully on the basis of rough trimming, so as to make the board nicer.
Corner Chamfer
The four corners after the edge banding are trimmed into a small arc, which is more smooth and does not stab hands.
Edge Banding & Bottom Grooving Solutions
- Integrated Edge Banding & Bottom Grooving: This advanced process combines seamless edge banding with precision bottom grooving (also known as bottom slotting or rebating) on a single machine. It is designed to create a professional finish while simultaneously cutting functional slots at the bottom of the panel.
- Precision Panel Slotting: The grooving at the bottom of the panel is essential for inserting back panels, drawer bottoms, or decorative hardware. By automating this within the edge banding workflow, you ensure maximum accuracy and a flush, clean edge finish.
- Optimized Furniture Manufacturing: Our solution supports high-efficiency production for cabinets, wardrobes, and modular furniture. It handles diverse materials and ensures that the bottom groove is perfectly aligned with the edge-banded surface, significantly improving the structural integrity and aesthetic of the final product
Scraping
The super-hard alloy R knife scrapes the fine lines of the edge strip to make it smooth.
Buffing
The cloth wheel quickly polishes the edge of the edge strip, and the polishing wheel has a larger use area and better polishing effect.
