To create sliding friction in barrel tumblers, rotary motion is combined with abrasive tumble media. The idea is simple: put rocks in a barrel, then roll it down a hill. Deburring and polishing occur when the parts slide against other parts.

Don’t forget the detergent. You might think that cleaning compound was intended for the metal parts, but in fact the tumbling media needs it. Cleaning compound adds lubricity to keep the pores open in the tumbling media. Once the pores in tumbling media become glazed over, the cutting action of the tumbling media will no longer work and metal parts turn out black. If the parts come out black, you forgot to put in the soap.

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.

The 2000-Series machines were designed with higher production requirements in mind. 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.

A centrifugal container tumbler works in a similar way to a Ferris Wheel, with smaller baskets placed on the edges. A centrifugal finishing device, also known as harperizing, has four barrels. Each of these barrels represents a place on a Ferris wheels and one large wheel. Each revolution on the flywheel results into one complete rotation each barrel. High centrifugal forces are generated by the flywheel, which is fast turning. These forces can generate up to 15 – 20 times the force and gravity of gravity. The contents will slide against each others under high pressure. The increased pressure allows faster processing of metal components and consistent results.

A grinding wheel can be described as a disc or cylindrical for cutting with abrasive or cutting action or sharpening cutting tools .

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.

Two major problems faced by a medical device manufacturer when developing a citric-passivation solution was the manufacturing process. After cleaning the parts, the water-break test had to be performed before passivating. The manufacturer could not use fully automated passivation. For quality control purposes, the system needed data tracking. Semi-Automated [...]

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.

No matter how many steps are involved in your process each step must take place separately. Also, polishing and deburring cannot be done at the same time. Instead, polish first and deburr second. If more steps are required, they must be done in ascending order. Polishing and deburring should be done first.

Top/bottom machines process both top and base surfaces in one pass. Every inch of every piece is processed exactly the exact same across 100% of the machine width.

There are so many options, it can be difficult to choose the right media. Use of incorrect media can cause serious problems like media sticking to the part or causing damage.

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.

Frequently Asked Questions

Metal finishing is the process of altering an object's surface in order to improve its appearance and/or durability. Metal finishing is related to electroplating, which is the electrodeposition of a thin surface coating of metal onto another.
