Vibratory Tumbling Media
Vibratory Tumbling Media
2.3.1 Consider the material of your parts:
Different types of media are suitable for different materials. For example, ceramic media with brown aluminum oxide abrasive is commonly used for the general deburring of hard metal materials, while plastic media is often used for aluminum and zinc die-casting parts.
2.3.2 Determine the desired finish:
Different types and shapes of media can produce different finishes. For example, ball-shaped media can produce a smoother finish, while pyramid-shaped media can be more aggressive in cutting and producing a matte finish.
different media shapes
2.3.3 Choose the appropriate size of media:
The size of the media should be smaller than the parts to ensure efficient tumbling and prevent parts from getting lodged. If the parts are much smaller than the media, you may need to consider using a reverse separation process.
2.3.4 Consider the shape of the media:
The shape of the media should be chosen based on the shape and complexity of the parts being tumbled. Choose media with shapes that are less likely to lodge in or damage your parts.
2.3.5 Determine the media-to-parts ratio:
The amount of media in the tumbler is critical to achieving a successful tumbling process. Generally, a 3:1 media-to-parts ratio is recommended for most tumbling applications. However, delicate parts may require a higher media-to-parts ratio to prevent parts-on-parts impingement.
2.3.6 Test and adjust:
It's important to test and adjust the tumbling process to ensure the desired finish is achieved. Make adjustments to the type, size, shape, and amount of media until the desired finish is achieved.
2.4 Compound and Water
Choosing the right compound for your vibratory finishing process is a critical step in achieving the desired finishing result. Consider the material being finished, the desired finishing result, and any environmental and safety factors when choosing a compound, and be sure to follow the manufacturer's instructions when diluting the compound.
Worcester (/ˈwʊstər/ (About this soundlisten) WUUS-tər) is a cathedral city in Worcestershire, England, 30 miles (48 km) south-west of Birmingham, 101 miles (163 km) west-north-west of London, 27 miles (43 km) north of Gloucester and 23 miles (37 km) north-east of Hereford. The population is about 100,000. The River Severn flanks the western side of the city centre, which is overlooked by Worcester Cathedral. The Battle of Worcester in 1651 was the final one in the English Civil War, where Oliver Cromwell's New Model Army defeated King Charles I's Royalists. Worcester is the home of Royal Worcester Porcelain, composer Edward Elgar,[1] Lea & Perrins, makers of traditional Worcestershire sauce, University of Worcester, and Berrow's Worcester Journal, claimed as the world's oldest newspaper.
