JONSEN SGP1300: Guaranteed Scratch-Free Edge Finishing for Coated Sheet Metal

The Critical Need for Edge Finishing Without Scratching the Surface

The finishing stage of sheet metal production presents a unique dilemma: precision is paramount, yet the part's surface integrity must be preserved. For high-value components clad in protective coatings—such as vinyl-coated stainless steel or painted aluminum sheets—traditional deburring often results in peeling, scratching, or marring the delicate surface. This damage necessitates time-consuming and costly manual checking and rework, ultimately compromising the quality of the final product. If your sheet metal still requires hand-checking after deburring, it's a clear signal that the finishing technology is lagging behind the demands of modern fabrication.

At JONSEN, the SGP1300 was specifically designed for parts where surface protection is critical. Its engineering is rooted in a fundamental shift from aggressive linear finishing to controlled, targeted planetary action, ensuring flawless edge finishing without scratching the surface.

The Flaw of Traditional Deburring on Protected Surfaces

Standard deburring equipment, which often relies on wide abrasive belts or linear brushes, achieves its results by dragging the media across the entire surface of the sheet metal. While effective for raw materials, this process is destructive to coated or filmed parts:

• Abrasion Across the Plane: Standard belts apply pressure across the entire surface area, causing fine scratches on painted or polished metals.

• Peeling Risk: The aggressive, linear motion can catch the edge of protective films (like vinyl or PVC), causing them to lift, tear, and peel, leading to immediate rejection of the part.

• Inconsistent Edge Results: These linear methods often struggle to achieve a consistent edge radius around internal cutouts and complex contours, forcing manufacturers to resort to slow, inconsistent hand-finishing.

The consequence is a substantial increase in hidden costs—labor time spent masking and unmasking, material waste from scratched sheets, and reduced throughput due to the necessity of manual inspection.

The JONSEN SGP1300 Solution: Precision Planetary Action

The innovation of the JONSEN SGP1300 lies in its planetary abrasive barrel technology, which offers a clean, non-compromising solution for edge finishing without scratching the surface.

Targeted Contact: How the SGP1300 Preserves Coatings

Instead of dragging belts across the whole surface, the JONSEN SGP1300 utilizes specialized abrasive barrels that rotate in a circular, or "planetary," motion while the workpiece moves forward.

1. Rotation Around the Edge: The abrasive media is precisely directed to contact only the edge of the sheet metal, applying pressure along the profile where the burr resides.

2. Bypass of the Surface: This unique rotational motion allows the barrels to effectively "wrap around" the burr, cleaning the metal edge while the main abrasive mechanism avoids contact with the protective film or painted surface.

This process ensures that the protective coating remains entirely intact, delivering no peeling and no scratching—a mandatory feature for high-value aesthetic components.

Deburring and Edge Rounding in One Go

The SGP1300 also provides powerful operational efficiency. The planetary action enables the machine to complete deburring and precise edge rounding in one pass. This eliminates the need for sequential machines or time-consuming repositioning, significantly reducing cycle time and overall production complexity.

Applications Where Edge Finishing Without Scratching the Surface is Paramount

The compatibility and precision of the JONSEN SGP1300 make it the preferred finishing solution across several demanding industries:

• Elevator Panels and Metal Façades: These parts are highly visible and often utilize brushed or pre-painted stainless steel. Any surface scratch or defect is immediately noticed. The SGP1300 guarantees a flawless finish that meets stringent aesthetic requirements.

• Kitchen Appliance Fronts: High-end kitchen panels and appliance fronts often use vinyl-coated or color-coated stainless steel. The machine's ability to protect the film while delivering a smooth, rounded edge is crucial for final product quality and consumer appeal.

• Control Cabinets and Enclosures: These parts require robust edge rounding for safety and functionality, particularly around cutouts for buttons and interfaces. The SGP1300 provides compatibility with stainless, zinc-coated, or color-coated metals, ensuring a consistently perfect finish regardless of the base material or coating.

FAQ: JONSEN SGP1300 and Protected Metal Finishing

1. How does the JONSEN SGP1300 handle different coating thicknesses?

A: The machine's head-to-part clearance and abrasive pressure are precisely controlled. Because the planetary abrasive barrels are engineered to only contact the edge profile, the thickness of the protective film or paint on the surface of the sheet does not impact the quality of the deburring process.

2. Can the SGP1300 handle complex laser-cut geometries and small holes?

A: Yes. The rotary and angular motion of the planetary abrasive barrels is specifically designed to reach into internal cutouts, wrap around irregular shapes, and deburr the internal edges of small holes, which is a common failure point for linear deburring machines.

3. What is the maximum width of the material that the SGP1300 can process?

A: The SGP1300 model is typically designed to accommodate sheet metal up to 1300mm wide, making it suitable for a vast majority of industrial and architectural panel production.

4. Does the protective film need to be removed before finishing?

A: No, that is the primary advantage. The JONSEN SGP1300 is designed to operate with the vinyl or protective film in place, avoiding the added labor cost and time required for pre-finishing removal and re-application.

5. How is the wear and tear of the abrasive barrels managed?

A: Due to the planetary rotation, the abrasive media wears down evenly. The machine's operational software and remote diagnostics allow for monitoring of abrasive performance, ensuring consistent output and signaling the need for timely media replacement.
