800mm Rotary Brush Dry Machine for Deburring Finishing Edge Radiusing Laser Oxide Removal And Heavy Slag Removal.

Rotary Brush dry machine is the ultimate machine for deburring, finishing, edge radiusing, laser oxide removal, and heavy slag removal. This machine offers the perfect solution for manufacturers who supply premium quality products. The high quality is achieved through a multi-rotating brush machine with eight abrasive flap brushes that deburr uniformly and round the edges of metal perfectly.

Drum – Rotary Brush – Hammerhead Rotary Brush Dry Machine is a highly versatile and powerful piece of equipment designed for a variety of metalworking tasks. It combines several finishing processes in one system, making it ideal for deburring, finishing, edge radiusing, laser oxide removal, and heavy slag removal.

1. Machine Processing Range:

1. Processed Materials: Carbon steel plates, etc.

2. Machine Functions:

This is a dry-processing machine with a combination of a steel hammerhead rotary brush station, a horizontal sanding belt station, and a planetary brush station. It is primarily used to handle deburring of the edges and holes of workpieces and to achieve metal plate surface slag removal, brushing, deburring, and polishing. It is particularly suited for deburring burrs produced during drilling, stamping, shearing, laser cutting, plasma cutting, flame cutting, etc., ensuring that the workpiece edges and holes achieve a small R-radius effect. The processing is safe, reliable, and produces high-quality results.

2. Working Principle:

  • First, a set of horizontally oscillating steel hammerhead rotary brushes removes large burrs and slag particles from the workpiece surface.

  • Then, a horizontal sanding belt station removes remaining burrs from the surface, sanding and cleaning the workpiece.

  • Finally, the workpiece passes through a planetary brush station composed of four groups of rotary brushes (with adjacent brushes rotating in opposite directions and the entire set rotating around the workpiece). This station performs high-speed centrifugal polishing, scraping, cutting, and filing on the workpiece’s edges and holes. The burrs are removed with no impact on the dimensional accuracy of the workpiece, and uniform R-radius edges of 0.2-0.5mm are created (adjustable depending on the abrasive and technique used).

All three stations (hammerhead, sanding belt, and rotary brush) can also operate independently:

  • The steel hammerhead station independently removes slag from workpiece edges.

  • The sanding belt station can independently perform brushing, polishing, deburring, and surface finishing.

  • The rotary brush station can independently deburr 360 degrees with no dead spots, particularly suited for laser-cut or CNC-punched sheet metal with protective film. It removes burrs without damaging the film or scratching the sheet metal.

The worktable conveyor system is equipped with a strong magnetic suction system to hold and fix the workpiece. For carbon steel workpieces larger than 50mm×50mm, it can be processed without special fixtures. The conveyor system has stepless speed adjustment via frequency conversion.

The machine is also equipped with a wet dust extraction system to efficiently handle dust generated during grinding. A high-flow fan pulls the dust into a dust collection chamber, where it is filtered using a water spray system. This ensures that clean air is discharged and grinding metal powder is recovered, supporting an environmentally friendly production process.

Key Components and Functions

  1. Drum Unit:

    • The drum unit is used for heavy-duty grinding, ensuring efficient removal of slag, burrs, and other imperfections caused by processes like laser cutting, plasma cutting, or flame cutting.

    • It provides aggressive material removal, preparing the workpiece for more delicate finishing processes.

  2. Rotary Brush Unit:

    • The rotary brush provides excellent edge rounding and deburring. It rotates to ensure that edges and internal holes are smooth and evenly processed, creating consistent results.

    • Effective for creating an edge radius up to 2.0 mm, ensuring all sharp corners are smooth and safe for handling.

  3. Hammerhead Rotary Brush:

    • The Hammerhead Rotary Brush offers a more intense brushing action, capable of handling tougher tasks like laser oxide removal and heavy slag removal.

    • This unique brush configuration allows for deep cleaning and polishing, especially for parts with challenging geometries or coatings.

Applications

  • Deburring: Removes burrs from various cutting processes such as laser cutting, stamping, and plasma cutting, ensuring a clean and smooth part surface.

  • Edge Radiusing: Smooths sharp edges and produces a consistent radius on part edges, preventing injury and improving safety.

  • Finishing: Achieves a superior surface finish, ready for further coating or painting processes.

  • Laser Oxide Removal: Effectively removes oxide layers that form on metal surfaces during laser cutting, improving adhesion for paint and coatings.

  • Heavy Slag Removal: Ideal for thicker materials where heavy slag forms, the drum and hammerhead rotary brush efficiently remove excess material without damaging the base part.

Machine Benefits

  • Versatile Processing: Capable of handling a wide range of metals, including stainless steel, carbon steel, aluminum, and other non-ferrous metals.

  • Multiple Functions: Combines grinding, deburring, and finishing into one machine, reducing the need for multiple processing steps.

  • Efficiency: The dry processing system allows for high-speed material removal and finishing, while reducing downtime and consumable costs.

  • Adjustable: Variable speed controls and adjustable pressure settings allow operators to fine-tune the process for specific material needs.

  • Consistent Results: Ensures uniform deburring, edge rounding, and finishing across large batches of parts, maintaining high quality and consistency.
