How to remove burrs without damage after laser cutting of laminated panels?

Overview

A key challenge commonly encountered with laser-cut coated metal parts is:
How to efficiently remove burrs without damaging the surface protective film?
Traditional manual sanding or heavy-duty polishing methods can easily lead to problems such as damage to the protective film, surface scratches, and poor processing consistency. Dyyrent has effectively solved this problem through an automated deburring + polishing + surface treatment system .
Dyyrent offers automated surface treatment solutions specifically for coated panels and precision metal parts .

I. Core Issue: Difficulties in Processing Laminated Boards

Common problems after laser cutting include:
Metal burr residue
The edges are sharp and need to be deburred.
The protective film is easily damaged during polishing or grinding.
Manual deburring is inefficient and inconsistent.
Poor surface consistency during mass production
The core problem is that traditional grinding and polishing processes are too "rough" and are not suitable for coated surfaces.

II. Core Solution: Industrial-grade Surface Treatment System

Modern processes typically consist of multiple controllable processing steps:

1. Deburring system

Commonly used equipment includes:
Deburring machine
Metal deburring and chamfering machine
CNC deburring machine​​
Hand deburring machine​​
Main function:
Removing burrs from laser cutting
Safety chamfering eliminates sharp edges
Keep the protective film intact
Key value: Achieving "deburring without damaging the membrane".

2. Controlled grinding, polishing and surface treatment

Equipment used:
Surface grinder
CNC grinding machine
Belt grinder
effect:
Increase surface roughness
Smooth surface
Preparing for subsequent polishing

3. Polishing and finishing system

The equipment includes:
Polishing machine
Polishing device
Automatic buffing machine
Industrial polishing machine
effect:
Improve surface smoothness
Improve appearance quality
Improve the adhesion of subsequent coatings
High-quality surface consistency is achieved through precise control.

4. Flexible belt abrasive processing system

Commonly used equipment:
Belt grinder
Belt sander
Sanding and polishing integrated machine (sander polisher machine)
Advantages:
Flexible contact processing reduces the risk of film damage.
Applicable to both planes and curved surfaces
Stable and uniform surface finish

III. Dyyrent Standard Process Flow:

Deburring → Grinding and polishing → Polishing → Finishing
 

IV. Common Problems and Process Challenges (FAQ)

Q1: What are the difficulties in deburring workpieces with protective films?

Traditional manual deburring using hand tools or conventional deburring workbenches is prone to damage due to its unreliability, easily leading to scratches on the protective film, tearing of edges, or secondary scratches on the workpiece surface. This not only damages the appearance but also fails to meet the marking requirements for laser-cut parts .

Q2: How does Dyyrent achieve "deburring without damaging the protective film"?

Dyyrent 's automated deburring machine uses flexible torsion and omnidirectional roller brush technology. Through precise control, the deburring and polishing equipment can accurately capture and remove burrs from metal plates at high speeds , maintaining only extremely gentle contact with the workpiece surface, thus ensuring that the protective film remains intact after the coated plate is polished .

V. Summary of Core Values
