A vibratory tumbler uses specialist abrasive media to automatically deburr and soften the edges of machined components. There are a number of different types of media kept in stock. | A vibratory tumbler uses specialist abrasive media to automatically deburr and soften the edges of machined components.

== Usage Information == | |||
=== Make sure there is fluid in the container === | |||
The tumbler works best with a small amount of tumbling fluid in the container - it doesn't need a lot, too much will stop it from working effectively - but it's important because it prevents hazardous dust from becoming airborne. The tumbling fluid is pre-mixed and is stored in the [[:Category:COSHH Cabinet - Morson Engine Room|Morson Engine Room COSHH cabinet]]. | |||
Over time the material can appear to dry out, this is usually because the fluid has settled to the bottom of the container. Add a small amount of fluid and let the tumbler run for a few minutes without your part in. | |||
=== Timing === | |||
Don't expect your parts to be done in less than an hour. Tumbling takes a long time, especially if you are working with hard materials like steel. Always test the process fully before comitting to a batch, or come and check on your parts regularly. | |||
For fully deburring hard steel parts expect to leave them tumbling for 6-8 hours. | |||
=== Tumbling is messy === | |||
Wear nitrile gloves when you are working in and around the tumbler. The slurry that is produced is messy and may stain your skin for a while because it contains very fine abrasive media. You will need to thoroughly clean your parts after tumbling, especially if they are going on for further processing like anodising or plating. | |||
Deburring and corner rounding | |||
You may find your parts come out with softer edges than when they went in - this is an expected part of the tumbling process. You can try to experiment with different media types and different durations. | |||
