Pre-milling Edge Banding Machine with 8-Function Workflow (Model HE-468PR)

The secret to the “Invisible Joint” finish. The HYG HE-468PR is our flagship industrial model, designed for furniture brands that refuse to accept visible glue lines or chipped edges.

This Pre-milling Edge Banding Machine integrates the most advanced surface preparation technology available. By adding a powerful Dual Pre-milling Station before the gluing unit, the HE-468PR shaves the panel edge perfectly flat and square immediately before application. Combined with Corner Chamfering (Rounding), this 8-function beast delivers a flawless result that standard machines simply cannot match.

The “8-Stage” Industrial Workflow

The HE-468PR executes a complete, defect-free process in a single 15-23m/min pass:

1. Pre-milling (The Upgrade): Dual diamond cutters remove up to 1-2mm of the panel edge to eliminate saw marks and swelling.

2. Gluing & Pressing: Applies adhesive to the now-perfect surface for maximum bond strength.

3. End Cutting: Precision flush cutting.

4. Rough Trimming: Heavy removal for thick tapes.

5. Fine Trimming: Creates the edge radius.

6. Corner Chamfer (Rounding): Rounds the vertical corners for a soft touch.

7. Scraping: Smooths out cutter marks.

8. Buffing: Polishes for high gloss.

Why Upgrade to the HE-468PR?

1. Pre-milling: Solving the “Black Line” Issue

Why do some edges look dirty? Because the panel edge wasn’t perfectly straight. The HE-468PR’s Pre-milling unit corrects cutting errors from the sliding table saw or CNC.

• Result: The edge band sits perfectly tight against the board, virtually eliminating the visible glue line (black line), especially on white or light-colored high-gloss panels.

2. Massive 6800mm Industrial Structure

Quality requires physical space. The HE-468PR is our largest machine, featuring a colossal 6800 mm chassis.

• Stability: This extra length (1.1m longer than the HE-468R) is necessary to house the pre-milling motors and isolate their vibration from the finishing units, ensuring micron-level precision across all 8 stations.

3. High-Power 17KW System

Pre-milling requires torque. We upgraded the powertrain to a massive 17 KW to drive the dual milling motors without slowing down the track.

• Reliability: Powered by Taiwan Delta Inverters and PLC, this machine is built to run 24/7 in high-volume production environments.

4. Complete Corner Processing

Like the R-series, this PR-model includes the Corner Chamfering unit. It creates a continuous, smooth radius around the entire perimeter of the board—top, bottom, front, and back—meeting the highest European quality standards.

Technical Specifications

Ideal Applications

• High-Gloss Acrylic Panels: Pre-milling is mandatory here to prevent ripples and ensure a glass-like reflection.

• Moisture-Resistant Kitchens: A tighter joint created by pre-milling prevents water vapor ingress better than standard banding.

• Luxury Office Furniture: Where both the visual “glue line” and sharp corners are unacceptable.

FAQ: HE-468R vs. HE-468PR

What is the main difference between R and PR models?

• HE-468R: Features Corner Rounding (7 functions). Great for smooth corners.

• HE-468PR (This Model): Adds Pre-milling (8 functions). It does everything the R model does, PLUS it re-cuts the board edge before gluing. Choose the PR if you want the absolute best bonding quality and zero glue lines.

Does Pre-milling change my panel size?

Yes, slightly. The pre-milling cutters typically remove 0.5mm to 1mm from the panel edge to clean it up. You simply need to account for this small allowance when cutting your boards on the saw, ensuring the final dimension is precise.
