In a centrifugal tumbling machine, an operator can control the speed of the tumbling. This control allows finer finishing and polishing at lower speeds as well as aggressive deburring, edge smoothing, and edge grinding at higher speeds.
For polishing large amounts of metal, the fastest and most cost effective method is to use a centrifugal barrel-tumbling machine. Also known as an industrial tumbler or rotary tumbler system, a centrifugal finishing machine uses the cyclical sliding action of a rotating barrel to grind the metal surface. Centrifugal barrel finishes are a form of mass finishing.
Centrifugal barrel grinding machines are the fastest, most cost-effective and efficient way to polish large quantities of metal. Also known by the names industrial tumblers, rotary tumblers, and harperizer systems, centrifugal barrel tumbling machines use a cyclical sliding movement to grind the metal surfaces. Centrifugal finishing is a method of mass finishing.
Our dry machines allow for more efficient and uniform finishing in industries like woodworking, metalworking and other composites. We distribute our products to all North American industries, in an effort help them achieve the highest quality finish.
Built in a heavy duty construction with a smaller footprint designed to accommodate a job shop with various applications such as deburring, dross removal, calibrating/dimensioning, edge radiusing or finishing.
With the many options available, there is a certain art to selecting the correct media. Using incorrect media can cause significant problems, such as media becoming stuck in a hole in the part or damaging the part.
Are you confused by flat parts? For centrifugal barrel finishing, flat parts like washers are a challenge. Because the parts stick to the barrel's side, they can wick together and stick to it. Only one side is deburred. Glass bead blasting media can be added to the centrifugal barrel finish process. The beads cover the parts and make them unable to stick to each other or the barrel. For parts that are prone to cup together, glass beads work well.
No matter the number of steps involved, each step should be done independently. This means that you can't do deburring and polishing at the same moment. Instead, first deburr, then polish. If more than one step are needed, the steps must all be done in ascending ordinal order of smoothness.
Our selection of dry metal machines provides solutions for a variety of applications, including graining, deburring, finishing, oxide removal, dimensioning, edge radiusing, and grinding. Depending on the types of materials that require processing, we offer either wet or dry metal machine configurations. We recommend dry machines for grinding processes due to the reduced levels of grit and coarse grit in environments where the temperature isn’t a major factor.
You can finish mass finishing with a centrifugal barrel twister wet or dry. Dry processes require a liquid lubricant or cleaner, while wet processes don't. The following elements are loaded into each of the four barrels to approximately 50-80% of their capacity.
Centrifugal barrel finishing systems are industry workhorses and are used with many types of metals, including brass, aluminum, steel, stainless steel, chrome, and titanium. Note that this type of system does not deburr plastic parts, because plastic is too pliable for this process.

No matter what your application is, we can help you find the right machine to fit almost any metalworking task.
The three types of work that centrifugal barrel-finishing machines can do are known as steps. You may not need to perform all the steps depending on the surface finish requirements of your product. There may be one step, two steps or three steps in your process.
Finishing operations, also known as finishing manufacturing, occur at the end of the manufacturing process, after the part has been formed and secondary processes have been completed.
