A Beginner’s Guide to Burnishing in Mass Finishing

Updated: May 9, 2023

Burnishing is a highly effective technique that can significantly enhance the surface finish of your metal parts. Whether you're working in a small shop or a large manufacturing facility, understanding the basics of burnishing can help improve product quality and efficiency. This guide from Finishing Systems will walk you through the fundamentals of this process.

What Is Burnishing Metal?

Burnishing is a finishing method commonly used in vibratory finishing machines, which can be either tub or bowl-shaped. It falls under the broader category of mass finishing, which involves the simultaneous finishing of multiple parts using vibratory systems. The process typically uses ceramic or porcelain media to polish surfaces to a high shine, but steel burnishing media is more frequently used due to its durability and effectiveness. The shape of the media—often a "balcone" style—can vary depending on the geometry of the parts being processed. The end result is a bright, smooth, and professional-looking finish.

3 Benefits of Burnishing

Burnishing offers several advantages that make it a valuable step in many manufacturing processes:

  • Fast Cycle Time: Burnishing with the right equipment and media can significantly reduce processing time compared to manual methods. A dedicated burnishing machine can handle large batches efficiently, especially when combined with the proper compounding agent to enhance performance. However, keep in mind that steel media requires a heavy-duty machine to support the load.
  • Compounding: Choosing the right burnishing compound is essential for success. It helps lubricate the media and improves the overall finish. Without the correct compound, even the best media won't deliver optimal results. Experimentation is often needed to find the perfect match for your specific metal type and application.
  • Key Elements: As with all mass finishing processes, the main components include the parts themselves, the equipment, the media, the compound, and water. Each plays a critical role in achieving the desired outcome.

The Burnishing Process

The burnishing process is typically carried out using a machine, making it ideal for industrial applications. One common method is ball burnishing, which uses a hard ball to apply pressure against the workpiece surface. This creates the necessary contact stress to achieve a mirror-like finish. Ball burnishing is especially useful when a specific color or luster is required during the finishing stage.

Lamination Base Film Matt

Lamination Base Film is a specially engineered BOPP film developed for thermal lamination processes. It acts as the foundational layer for EVA adhesive coating, enabling strong and consistent bonding to paper and cardboard substrates. This film is widely used in sectors such as packaging, publishing, and commercial printing, where high adhesion strength, durability, and compatibility with various printing methods are crucial. Depending on application needs and surface finish preferences, lamination base films are available in matte, gloss, and soft-touch varieties. Matte films provide a smooth, non-reflective surface ideal for a sophisticated look, gloss films deliver high clarity and vibrant color enhancement, while soft-touch films offer a silky, premium texture. These films are well-suited for high-speed lamination lines and perform exceptionally in post-lamination treatments such as spot UV, foil stamping, and die cutting, ensuring both visual appeal and functional reliability in final products.
