Vibra Finish Limited offers a wide variety of services for finishing metal parts, and a key one is deburring. As many machine parts do not work properly with raised edges or rough spots, removing burrs is a major part of finishing. There are several different ways of approaching this procedure, ranging from vibratory deburring methods to using a centrifugal-disc deburring machine. A key benefit of these finishing methods is that they keep labour costs down.
One method Vibra Finish Limited uses is a vibratory deburring machine. These beneficial machines offer constant quality through computerized and controlled conditions that run and keep every batch consistent. No surfaces are touched, nicked, scraped, or damaged, and numerous elements are qualified of being fired together, which results in significant reduction of piece-part costs. With larger equipment parts, dry process and polishing techniques are used to deburr smaller gears with elaborate tooth profiles.
Centrifugal disc deburring is a more aggressive approach, but with less part-on-part impingement than one might expect. These deburring machines are three-part systems: a tub where users place media and parts for deburring; a disc at the tub bottom that transfers centrifugal energy to the media and parts, and a motor to spin the disc. The benefits of centrifugal deburring methods include faster rates, high flexibility and control, and better finish quality. Rapid abrasive wear is an occasional drawback, but certain media can help prevent this issue.
Shot blasting is another one of the deburring methods Vibra Finish Limited employs. This technique also cleans, polishes, and strengthens the metal. It is necessary to prepare metal for surface coats, such as plating, paint, and overlays. Shot blasting is commonly used for preparing new parts and restoring old ones in the automotive sector.
Finally, tumbling – also known as barrel finishing – is a surface-improving operation in which the user places parts, media, and compound in a barrel that rotates at a predetermined speed. Among other purposes, this deburrs parts to a high finish. Aluminum oxide can be added if irregular size and shape are not important. It is best to start at a low speed to cut the burr, instead of rolling it over, and then increase the speed.
