1350mm Sheet Metal Edge Rounding Machine for Laser, Plasma and Flame Cut Parts

Product Introduction

The 1350mm Sheet Metal Edge Rounding Machine is designed for efficient edge deburring and rounding of metal parts produced by laser cutting, plasma cutting and flame cutting.

With a maximum working width of 1350 mm, the machine is suitable for processing a wide range of sheet metal parts and metal components. It removes sharp edges and burrs while creating a smooth and consistent rounded edge along the workpiece.

The machine is especially suitable for manufacturers that require consistent edge quality before powder coating, painting, welding, plating or assembly.

Edge Rounding for Different Cutting Processes

Laser Cut Parts

Laser cutting provides high cutting accuracy but can leave sharp edges and fine burrs on the workpiece. The machine removes these sharp edges and provides a smooth, uniform edge finish.

Plasma Cut Parts

Plasma-cut components can have rough edges, burrs and cutting residues. The machine helps remove these imperfections and improves the overall edge quality of the workpiece.

Flame Cut Parts

Flame cutting is commonly used for thicker carbon steel plates and large metal components. The 1350mm Edge Rounding Machine can process flame-cut parts to remove sharp edges and burrs and improve edge safety.

Why Edge Rounding Is Important

Sharp edges and burrs are common after laser, plasma and flame cutting. If they are not properly treated, they can cause handling injuries, affect coating quality and create problems during assembly.

Edge rounding removes sharp edges and creates a more uniform radius. This provides a safer workpiece and improves preparation for subsequent surface treatment.

Typical processes after edge rounding include:

Deburring → Edge Rounding → Cleaning → Painting / Powder Coating → Assembly

Suitable Materials

The machine can be used for:

• Stainless Steel

• Carbon Steel

• Mild Steel

• Aluminum

• Galvanized Steel

• Copper

• Other Sheet Metal Materials

The abrasive system can be selected according to the material type, thickness, burr condition and required edge radius.

Equipment Specifications and Structure

Key Features

1. Flexible Processing: Accommodates both flat and 3D parts, with a minimum size of 50 x 50 mm. A powerful vacuum table ensures parts are held securely in place.

2. Effective Edge Rounding: Achieves a 2mm radius on edges for uniform rounding on all sides and holes, suitable for sharp edges from laser, plasma, and waterjet cutting.

3. Versatile Functionality: Equipped with a wide abrasive belt and multiple roller brushes for multi-directional deburring, grinding, and polishing, ensuring smooth edges without damaging coatings or films.

4. Efficient Dust Collection: Equipped with a high-flow wet or pulse vacuum cleaner to capture and filter grinding dust for a safer and cleaner work environment.

Benefits of the Equipment

• Enhanced Productivity: Continuous feeding increases throughput and reduces processing times.

• Improved Quality: Consistent and high-quality surface finishes surpass manual methods.

• Cost-Effective: Reduces per-unit processing costs compared to manual labor.

• Environmental and Operator Safety: Effective dust collection for a cleaner workspace, reducing health risks and allowing metal powder recycling.

This equipment is designed for comprehensive edge finishing, burr removal, and surface treatment of metal plates, ideal for a range of metal types, including carbon steel, stainless steel, aluminum, copper, and other non-ferrous materials. 

I. Processing Scope

1. Materials: Works with various metals such as carbon steel, stainless steel, aluminum, copper, and other non-ferrous metals.

2. Functions:

• Edge and Hole Deburring: Effective removal of burrs from all directions on edges and holes, leaving a clean, smooth R-arc effect.

• Surface Treatment: Achieves metal plate hairline finishes, oxidation skin removal, and polishing.

• Equipped with a combination of a dry sand belt and eight universal sand tablet roller brushes, it is optimized for:

• Suitable for addressing burrs from processes like stamping, shearing, laser cutting, plasma cutting, and flame cutting.

II. Working Principle

1. Processing Stages:

• Sand Belt Station: Removes large burrs and slag from the workpiece surface.

• Universal Sand Tablet Roller Brush: The eight groups of roller brushes handle edge and inner hole deburring with high-speed centrifugal grinding, scraping, and filing. The process ensures smooth R-angle formation without affecting dimensional accuracy.

2. Independent Functionality:

• Sand Belt Station: Can independently handle hairline finishing, polishing, and slag removal.

• Sand Rolling Brush Station: Operates independently for 360-degree deburring, especially effective on coated sheet metal (e.g., laser-cut or CNC-punched parts), with minimal risk of damaging protective films or scratching surfaces. Soft abrasive wires are used to selectively target burrs without harming the coated surfaces.

3. Conveying and Dust Collection System:

• Equipped with a vacuum negative pressure system to securely hold workpieces, even as small as 50mm x 50mm, allowing consistent machining.

• Integrated wet vacuum dust collection system with a high-pressure fan, which safely absorbs and filters dust, improving the work environment by recycling metal powder.

III. Advantages of the Equipment

1. Efficiency: Continuous feeding enables high throughput, meeting the demands of large orders.

2. Quality Improvement: Ensures consistent surface treatment and finish quality superior to manual processing.

3. Cost Efficiency: Reduces per-unit processing costs compared to manual finishing.

4. Safety and Environmental Benefits: Provides a safer, cleaner working environment by controlling dust and enhancing operator safety.
