In metal fabrication, the cutting process is only one stage of part preparation. Once a flat metal component has been cut, the remaining burrs, sharp edges, and slag can affect how that part performs in later stages of production. These issues may influence assembly fit, coating coverage, handling safety, and the amount of rework required before the part is ready for use.

As a result, many manufacturers use automated deburring and edge rounding systems to create a more controlled finishing process. The MG RD700 Metal Sanding Machine from Motimac is designed for this stage of production, combining burr removal and edge rounding in a single machine for flat metal plates.

Simultaneous Deburring and Edge Rounding

The MG RD700 performs both deburring and edge rounding in a single pass. This allows burr removal and edge treatment to take place during the same operation rather than requiring separate processing stages –– reducing the need to move parts between multiple finishing processes while simplifying workflow planning within fabrication environments.

To support a uniform finish across a wide range of flat metal components, the machine can achieve edge rounding up to R0.2mm. Manufacturers can create smoother edges while reducing the amount of handling required throughout production by combining these finishing tasks into a single operation.

Flextrim Disc Brushes

The machine uses Flextrim disc brushes to contact the edges of the workpiece from multiple angles which helps create a more uniform edge profile across the entire part. This multi-directional contact is particularly useful when processing components with varying geometries, as it allows exposed edges to receive more consistent treatment throughout the finishing operation.

The brushes are also designed for fast abrasive replacement, making routine maintenance and consumable changes more straightforward for operators. This allows the machine to remain focused on production –– regardless of volume –– while helping maintain finishing quality over time.

Suitable for Different Metal Processing Applications

Since production environments rarely process only one type of material, the MG RD700 is appropriate for various flat metal plates –– including carbon steel, stainless steel, and other commonly used materials. This flexibility lets fabricators use the same machine across multiple projects without changing equipment.

Its 700mm effective working width provides the capacity needed for a wide range of fabrication operations while upholding a compact footprint that fits comfortably within existing workflows.  This strikes a nice equilibrium between performance and machine size for manufacturers looking to maximize floor space.

Consistent Results Among Different Workpieces

Achieving the same edge finish across assorted workpieces can be difficult when they vary in size, thickness, production requirements, etc. The MG RD700 meets this challenge through its fixed-table design and individually controlled working units.

Rather than moving the workpiece through a fixed finishing setup, the MG RD700 uses a fixed-table design with individually controlled working units. This layout allows processing parameters to be adjusted for different workpiece requirements as it maintains stable contact throughout the finishing process.

The machine also includes a standard vacuum table that helps secure smaller workpieces during operation. By reducing unwanted movement during processing, the vacuum table supports more stable edge treatment and allows smaller components to be processed with greater control.

Safety and Environmental Performance

Manufacturers are increasingly improving workplace conditions while striving to meet environment requirements. That in mind, safety and dust control are of growing importance in today’s fabrication facilities.

The MG RD700 supports this with a fast-response emergency stop system and an upgraded dust extraction structure that captures dust generated during finishing operations at the source, helping keep a cleaner work area throughout production.

Frequently Asked Questions

Q: What is a metal sanding machine used for?

A: A metal sanding machine is used after cutting or punching to clean up the edges and surfaces of metal parts. This often means removing burrs, reducing sharp edges, managing slag and creating a more controlled finish before the part moves on in the production process.

Q: What is deburring in metal fabrication?

A:Deburring removes the unwanted raised edges or rough fragments left on a metal part after cutting, punching, or machining. If burrs are not removed, they can lead to extra rework later in the production process.

Q: Why is edge rounding important?

A: Edge rounding creates a smoother, more even edge profile instead of leaving a sharp corner on the part. This can be especially important before coating, since sharp edges can make it harder for paint or powder coating to cover evenly.

Q: What materials can the MG RD700 process?

The MG RD700 works with various flat metal plates, including carbon steel and stainless steel ––particularly useful for fabrication environments that process different flat metal components within the same workflow.

Q: Can the MG RD700 perform deburring and edge rounding at the same time?

A: Yes. The MG RD700 is designed to combine deburring and edge rounding in a single pass, allowing burr removal and edge treatment to happen during the same operation instead of requiring separate finishing steps.

Q: Can small workpieces be processed on the MG RD700?

A: Yes. The MG RD700 includes a standard vacuum table designed to help secure smaller workpieces during processing. This added stability helps maintain consistent contact throughout the finishing operation.

Q: Why combine deburring and edge rounding in one machine?

A: Combining these processes into a single machine allows both operations to be completed during the same workflow. This can reduce the need for additional handling and simplify part processing before the next stage of production.
