DEBURRING BARREL TUMBLERS

Deburring Barrel Tumblers are the most versatile option of parts finishing systems. Reasons of application for this equipment include heavy deburring, high polishing, degating, and parts drying. If you have a heavy load and a vibratory finisher isn’t a good option, then a barrel tumbler is an ideal alternative. The barrel size options cover everything from a few ounces up to the size of a small car, and everything in between. When estimating the required barrel capacity, keep in mind the barrel should only be half full during its usage.

During the process, the load inserted into the barrel slowly rolls and cascades to achieve the desired surface finish of the product. In particular, this process provides several options that vary your outcome. First, the process may be wet or dry, meaning with or without water. Second, media isn’t necessary in this process, however if its incorporation generates your preferred outcome, it can be easily included.

Wet barrel finishing, the system containing water, is a batch system for the removal of excess material or the polishing of parts. Employing water and Finishing Compounds in the process forms radii, removes burrs, improves surface appearances, polishes, and cleans. Wet barrel tumbling is a wise choice for processing metal and plastic parts.

Dry barrel finishing is a batch system for mass polishing or removing excess material from plastic or metal parts without liquids. Similarly, dry tumblers also form radii, but also deflash, polish, and grind parts. If you need to finish delicate parts that risk damage in a wet barrel, dry tumbling is the best choice. A dry system produces a smoother and higher finish. Therefore, the final appearance looks shockingly hand-buffed with greater uniformity.

If you’re unsure what options and set-up best suits your project needs, a representative from Kramer is happy to assist you.

One of the most reliable methods for deburring and polishing metal parts is to employ an industrial-grade barrel tumbler. This deburring equipment is specially designed to tumble metal and plastic parts and components to the required finish. Abrasive media and finishing compounds are added to the tumbler to ensure a perfect finish even in recessed surfaces. For industrial and manufacturing applications, we have the equipment you need for your application.

Applications

Tumblers can be semi-automated or even fully automated. The action of the media on the work piece is what is doing the crucial job of making certain parts are finished as expected. Though Barrel tumbler deburring machines have been around a long time, its basic principle hasn’t changed much. You place media in the barrel, add the parts and rotate the barrel

Each of these types of barrel tumblers are appropriate for different types of parts and applications. The viability and versatility of this technology continues to be proven given the increase in tumbling applications with so many kinds of parts being manufactured in today’s world.
