Masterclass in Metal Tumbling and Deburring Services Explained

When it comes to efficiently removing metal burrs and achieving smooth edges on metal parts, Midland Deburr & Finish stands out as an expert provider of tumbling and deburring services. Utilising advanced techniques and state-of-the-art machinery, they offer competitive prices coupled with excellent service. Let's delve into the various types of metal tumbling and deburring techniques they employ:

Barrel Tumbling

Removing metal burrs manually would be time-consuming and labor-intensive. This is where barrel tumbling comes into play. Midland Deburr & Finish utilises barrel tumblers to deburr numerous small parts simultaneously. This method excels at rounding off corners and eliminating sharp burrs on parts with heavy radiuses. Different speeds and amplitudes of vibration are employed based on the parts being deburred. High speeds and large amplitudes efficiently roll over burrs and smooth out sharp edges.

Vibratory Deburring

Vibratory deburring operates akin to a filing action. As upward, angular force is applied, metal parts and media rub together, creating a cutting action. Midland Deburr & Finish employs vibratory tumblers that exert a force 5 to 10 times greater than barrel tumbling machines, resulting in shorter cycle times. This technique can be utilised on fragile parts due to the absence of unequal forces acting on them.

Media Used in Deburring Machines

Both barrel tumbling and vibratory deburring utilise various types of media to achieve soft, clean edges on metal parts. Midland Deburr & Finish employs media such as stone, ceramic, or plastic beads in their deburring machines. Water is added to wash away dirt and carry the media, with chemicals used when necessary to enhance the quality of the finished product.

Types of Metal Burrs

Midland Deburr & Finish classifies deburring not only by cutting direction but also by the mechanism by which burrs are formed. They deal with four different types: Poisson, rollover, tear, and cut-off burrs.

Materials Used in Tumble Deburring

Various materials can be employed in tumble deburring, including ceramic, plastic, steel, and organic compounds. Ceramic media is ideal for grinding and polishing hard materials like steel, while plastic media is recommended for softer metals such as aluminum, zinc, and brass. Steel media is effective for cleaning and burnishing steel items, albeit being more expensive. Organic media, like walnut shells and corn cob granules, offer a cost-effective solution for achieving a high-gloss finish.

Polishing in Tumble Deburring

In the final polishing process, Midland Deburr & Finish utilises powdered polish, water, and sometimes tiny plastic pellets to cushion the stones as they tumble, ensuring a uniform distribution of polish without chipping.

Size Considerations

Midland Deburr & Finish emphasises the importance of selecting the appropriate media size to prevent it from getting stuck in the component, which could lead to time loss and potential damage to the parts.

Midland Deburr & Finish offers comprehensive metal tumbling and deburring services, utilising various techniques and media to ensure high-quality results at competitive prices, all backed by exceptional service.
