In ascending order of smoothness, there are three types of work an industrial tumbler machine does.
A grinding wheel is either a disc, or a cylinder used for cutting and abrasive machining .
A centrifugal barrel tumbler can perform mass finishing either wet- or dry. Wet processes use liquid lubricants, cleaners, or abrasives, while dry processes do not. Each barrel is filled to 50-80% capacity with the following elements.
A centrifugal barrel components tumbler can remove 95% the labor involved in hand deburring or polishing. This dramatically reduces hand sorting, which increases productivity and returns on investments. A centrifugal bar finisher makes it possible to reduce the use of a microscope and to locate and remove defects on every part.
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.
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.
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.
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.
The polishing step is usually a dry process using ground-up corn cob as media, with polishing compound embedded. Ground-up walnut shells are also used as media for dry processing.
Polishing is usually a dry process with ground-up corncob used as media. The compound embedded in the polishing agent is included. Also, dry processing can be made with ground-up walnutshells.

Flat parts make you feel lost? Flat parts, like washers, pose one of the most difficult challenges in centrifugal-barrel finishing. Parts tend to stick to the barrel and wick together so that only one side can be deburred. To solve this problem, you can add glass bead blasting medium to the centrifugal drum finishing process. The beads protect the parts from sticking to each another and to the barrel. Glass beads can be used for parts that have a tendency to cup together.
Finishing mortars and concretes; natural and artificial masonry materials; decorative ceramics; materials and items made of wood, paper, glass, plastic, and metals; and paints and varnishes are the most common finishing materials used in modern construction.
Textile Machinery Types Textile Machineries are classified into two types: Textile processing machinery Textile processing machinery, equipment, and accessories
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.
