Industry workhorses, centrifugal barrel finish systems can be used to finish many metals, such as brass and aluminum, stainless, chrome, and steel. Plastic parts are not deburred by this type system, as plastic is too malleable for this process.
The Gulf States Saw & Machinery Co., Inc. portfolio consists of everything from a simple rotary vibrationator to fully automated, robotic surf finishers. Gulf States Saw & Machinery Co., Inc. has a strong core strength in developing and implementing custom-designed processes and systems. Metal, ceramic, wood...deburring, rust removal, or polishing: The options available to Gulf States Saw & Machinery Co., Inc. mass finish machines are virtually limitless.
In ascending order of smoothness, there are three types of work an industrial tumbler machine does.
Gulf States Saw & Machinery Co., Inc. can help you find the right dry machine for your needs. Our customers are provided with a range o dry metal machines which will improve their efficiency, safety, and dependability in metalworking.
Tumbler media is an abrasive that's used in mass finishing to remove the burrs from a metal surface. Tumbler media can come in many forms.
Barrel tumblers use rotary movement with abrasive tumbling media to create sliding friction. Imagine putting rocks into a barrel and rolling it down a hill, and you have the general idea. The deburring or polishing occurs as the parts slide against the media and other parts.
The versatile and widely used centrifugal barrel finishing machines are great tools for metal finishing.
The 2000-Series machines are made with heavy production requirements. They are designed to handle such applications as deburring, slag grinding, calibrating/dimensioning, edge radiusing, paint/surface preparation, finishing/polishing or a combination of these applications.

The polishing step is usually done dry using ground-up corncob as media and embedded polishing compound. For dry processing, ground-up walnut shells can be used.
The versatile centrifugal barrel finish machine can be used in many industries for metal finishing.
Regardless of the number of steps in your process, each step must be performed separately. In other words, you cannot perform deburring and polishing simultaneously. Instead, deburr first, then polish. If more than one step is required, the steps must be performed in ascending order of smoothness, with deburring first and polishing last.
For centrifugal barrel finish, it is essential to use the correct tumbling medium. The wrong media, and especially the wrong geometry can increase the cycle time of parts. Processing time can be significantly slowed down by using cones and cylinders for tumbling media if they aren't needed.
Vibratory tumblers use side-to-side movements to shake a container or bowl in a circular fashion, similar to those used for rock polishing. Finishing occurs when the parts and media are rubbed against each another.
