Flummoxed by flat parts? Flat parts such as washers present one of the toughest challenges for centrifugal barrel finishing. The parts tend to wick together or stick to the side of the barrel, so only one side gets deburred. The solution is to add glass bead blasting media to the centrifugal barrel finishing process. The beads coat the parts so they can no longer stick to the barrel or each other. Glass beads also work well for parts that tend to cup together.
The two main options for metalworking machines that can finish and deburr are wet and dry. These machines accomplish the same thing using different methods. Wet machines spread a coolant mix on the surface of the processed parts. Dry machines operate without this mix.
It is a rule of thumb that the darker media the better it cuts. Plastic media that is very dark will be faster-cutted with a more aggressive product. A lighter color media is more likely be mildly cut for mass finishing with mildly abrasive abrasives.
The centrifugal finishing machine for metal finishing is a versatile tool.
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 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.
Want a matte or satin finish? Add aluminum oxide blasting media to your centrifugal barrel finishing process, and the resulting part will be matte instead of shiny.
A centrifugal barrel tumbling machine is the most efficient and cost-effective method of deburring large numbers of metal parts and/or polishing them at once. Also called an industrial tumbler, circular tumbler, or harperizer, the centrifugal bar finishing machine uses a sliding action to grind metal surfaces. One type of mass finishing is centrifugal bar finishing.
Centrifugal barrel finishing requires the use of the right tumbling media. The cycle time for parts can be doubled if the media is not right, especially if it's the wrong geometry. If you are not using cones or cylinders to tumble media, it can significantly slow down the processing time.
The vibratory tumbler uses a side-to–side motion to shake a tub or bowl in a circular pattern, much like the rock polishing kit that many of us used as children. As the media and parts are sheared against each other, the finishing takes place in a scrubbing motion.
Gulf States Saw & Machinery Co., Inc. tabletop folders offer the perfect combination of speed, precision, and ease of use, making them ideally suited for small offices, schools, and corporate environments. Automatic programmable models store fold programs in memory and can be set up to run at the touch of a button.
The safety of workers is enhanced by the use of a deburring device. This reduces repetitive motion injuries like carpal tunnel syndrome. The machine's centrifugal barrel design is far more ergonomic that hand work. The only downside to centrifugal tumblers is that they require operators to manually load each barrel. However, the machine's high speed compensates for this labor intensive.
There are three main types of work that an industrial tumbler can do, in ascending or decreasing order of smoothness.
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.
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.
