Vibratory Finishing
Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, clean, and brighten. Stampings, screw machine parts, and castings are just some examples of parts processes using vibratory finishing.

Burnishing is mass finishing process takes advantage of a vibratory finishing machine’s energy (using either steel or ceramic media) to smooth and brighten the surface of metal parts. In some cases, it can generate a metal finish comparable to hand polishing. It is often used to increase the lubricity of the parts finished or for a pre-plated finish to enhance the luster of a part after plating.

Mass Finishing
Mass finishing is a metal finishing service utilizing mechanical finishing procedure. This approach is a more cost-effective way of improving the quality and functionality of manufactured parts such as stampings, screw machine parts, and castings. can be used to deburr, radius, descale burnish, clean and brighten parts.

Edge Break & Deburring
Following a stamping or machining process, the residual material left over is commonly referred to as burrs. Our specialized deburring vibratory service, Microfinish can take manufactured components of various sizes and remove the unwanted “burrs” or sharp edges with a variety of approaches, depending on the material.

The industry term “radiusing” refers to a more aggressive removal/rounding of sharp edges than “edge break” or “deburring”. Radiusing is the ideal metal finishing procedure addressing the issue of products getting stuck or catching on other parts which, when assembled with other components, can cause the products to malfunction.

Microfinish uses the descaling metal finishing technique on parts that have been heat-treated or welded. Descaling is designed to remove heat scale and improve the surface finish of the manufactured product.
