Editing Instructions:Large Finishing Tumbler (section)

== '''Machine Overview''' ==
The Mr. Deburr 300DB is a deburring and polishing machine. It is designed to deburr parts, and polish a variety of materials using different sets of media. This machine is particularly good at removing rust and getting a high polish and consistent finish on completed metal parts. 

=== '''Tumbling Media''' ===
Currently we have 3 sets of Shop supplied media:

* I would like to combine the abrasive media info here because at least some of it can be used in both tumblers and the two sandblasters. Any objections if I move this section to [[Template:Abrasive media in the metalworking room]] that has already been applied to the main page of all these tools?

# Grey Ceramic 
## The Grey Ceramic media is designed for steel and stainless steel. It cuts hard and fast, and leaves a matte finish. 
# Green Resin
## The Green Resin cones are designed for softer metals like aluminum and brass.
# Corn Cob Polishing Media
## Corn cob polishing media can get a highly polished finish on parts, after they go though the primary polish. For example, if you want to mirror polish an aluminum part, first run the part in the Green Resin media to get a consistent finish, then finish the polish in the corn cob media. 
## Note - we do have corn cob media for both Aluminum and Steel, take care not to cross contaminate the polishing media.

# Members are welcome to bring their own media if they have a particular project. Please consult with the trainer to ensure we have space for storage, and to determine which lubricant is ideal for the task/media. 

<nowiki>*</nowiki> '''NEVER tumble steel in the Green Resin Media, and NEVER tumble aluminum in the Grey ceramic media due to the risk of contamination. This creates a very bad finish and the media is extremely time consuming to clean.'''

=== '''Lubrication''' ===
Most media is used with a lubricant. North Forge supplies the lubricants for each media. The lubricant is located above the tumbler in dispenser bottles and is labeled for each material. To avoid splash damage, '''wear safety goggles''' when dispensing lubricants. A minimal amount of lubricant is ideal, as too much will foam up and cause a mess, and not allow the media to cut properly. '''One pump of lubricant is sufficient for optimal operation.'''

Corn Cob media should be run dry.
