Centrifugal barrel tumbling machines are especially well-adapted for removal of significant burrs and blending lines left by machining. They also offer excellent performance in polishing and burnishing applications. When used with various types of ceramic and organic (e.g., corn-cob) media, centrifugal barrel machines can achieve virtually any part finish from super-fine surface finish polishing to burr removal.

A centrifugal barrel parts tumbler eliminates 95% of the manual work involved in polishing or deburring parts by hand. The reduction in hand sorting is a significant improvement on production and return of investment. A centrifugal barrel finisher eliminates the need to use a microscope to find defects and remove any burrs. This reduces waste and costs.
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.
No matter how many steps your process has, each step must always be completed separately. Deburring and polishing cannot be done simultaneously. Instead, you should deburr first, and then polish. If more than 1 step is needed, the steps should be performed in ascending ordescending order of smoothness. For example, polishing first and deburring last.
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.
Perfect for digital applications, the GoCrease creasers allow documents printed on heavy or coated stock to be creased prior to folding, creating a crisp more accurate fold with no cracking
Air is forced between sheets by the AJ 700 paper jogger to reduce jogging times and prevent static buildup. This allows digital copies and press sheets to be dried right away after printing, to avoid offset. Gulf States Saw & Machinery Co., Inc. drills have a 2-inch deep drilling capacity and movable tables that are mounted on bearings to ensure precise paper positioning. The tabletop models 25 and 55 have 5 pre-set patterns that can be chosen at the touch of a dial.
Do not forget to add the detergent. Although you might believe that the cleaning compound is only for metal parts, the detergent is essential for the tumbling media. Cleaning compound provides lubricity that keeps pores open in the tumble media. The cutting action of the tumble media stops working if the pores become clogged. Metal parts will turn black. You have probably forgotten to add the soap if the parts turn black.
We are able to customize solutions for our customers in our in-house lab. This allows us the ability to develop a custom, innovative solution.
A centrifugal barrel tumbler works on a principle similar to a Ferris wheel, with smaller baskets mounted on the edges of a large wheel. A centrifugal finishing machine, or harperizing system, has 4 barrels, each barrel representing a seat on a Ferris wheel, and one large flywheel. Each revolution of the flywheel results in one complete rotation of each barrel. The fast-turning flywheel generates extremely high centrifugal forces, up to 15 – 20 times the force of gravity, causing the contents to slide against each other under high pressure. The increased pressure allows for fast processing times of metal parts, as well as smooth, consistent finishes.
Top/bottom machine processes the top and bottom surfaces simultaneously with 100% uniformity. Each square inch of each part is processed exactly the way it was intended over the entire width of the machine.
As a general rule, the darker the media, the faster it cuts. For example, if plastic media is very dark, it’s likely to be fast-cutting with a more aggressive abrasive. Lighter-colored media is more likely to be mild cutting for mildly abrasive mass finishing.
Gulf States Saw & Machinery Co., Inc. is known for its bookletmakers and finishing systems that are quick and versatile. The Sprint series models have a strong reputation for reliability and performance in the printing finishing industry. The SF2 bookletmaker uses wire-fed stitching technology that was previously only available in larger systems, which can run up to three times as much.
Finishes are applied at the end of a construction or manufacturing process to form the final surface of an element. They can protect the element they finish from impact, water, frost, corrosion, abrasion, and other elements, as well as be decorative.
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.
Finishing processes can be used to improve the following characteristics: appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control surface friction.
