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.

For centrifugal barrel finish, it is essential to use the correct tumbling medium. The wrong media, and especially the wrong geometry can increase the cycle time of parts. Processing time can be significantly slowed down by using cones and cylinders for tumbling media if they aren't needed.

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.

Tumbler media is an abrasive that's used in mass finishing to remove the burrs from a metal surface. Tumbler media can come in many forms.

Barrel tumblers use rotary movement with abrasive tumbling media to create sliding friction. Imagine putting rocks into a barrel and rolling it down a hill, and you have the general idea. The deburring or polishing occurs as the parts slide against the media and other parts.

Industry workhorses, centrifugal barrel finish systems can be used to finish many metals, such as brass and aluminum, stainless, chrome, and steel. Plastic parts are not deburred by this type system, as plastic is too malleable for this process.

Machines in the 2000-Series are designed to handle heavier production demands. 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.

Barrel tumblers make sliding friction using rotary movement combined with abrasive, tumbling media. Imagine you are putting rocks in an old barrel and rolling it up a hill. As the parts slide on the media, or against each other part, deburring or polishing happens.

What machines are used for finishing

In ascending order of smoothness, there are three types of work an industrial tumbler machine does.

Frequently Asked Questions

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.

The Inovatec Automatic Surface Finishing Machine has a PLC control system that allows you to control the entire surface finishing process. It is a completely automated and labor-saving solution. Suitable for deburring and polishing a large batch of small parts at once.

The law of attraction between positively and negatively charged particles underpins the finishing technique of applying a coating to a metal surface. The paint is usually positively charged, while the support to be painted is negatively charged because it is wired to a strong electric field.
