Information About Deburring
In general, media comes in two types: plastic and ceramic. Both medias come in many different shapes and sizes, as well as many levels of aggressiveness. In selecting media, you need to figure out the shape and size as well as how aggressive the media needs to be. For shape and size you would want to pick a media that will get into the smallest places of your parts, but not get lodged. Plastic media in a general purpose formulation (VF-X) is usually used for deburring aluminum and ceramic media, whereas plastic media in a super fast formulation (VF-SF) is typically used for deburring steel and stainless steel. Larger media will be more aggressive than the small media of the same composition. Smaller media will generally give your part a better finish.
Fluid System and Compound
During the deburring process, water and compound are circulated through the tank. The compound is like a soap and has different additives depending on the type of material you are deburring, i.e. aluminum, steel, stainless steel, brass, copper, zinc, etc. The compound lubricates and cleans the media as well as the parts.
For most aluminum parts to get an edge break, it will take about 30 minutes of run time. To achieve a uniform look to your part, the common run time will be between 45 minutes and 1 1/2 hours. For steel parts with ceramic media, the run times will be longer depending on how much deburring needs to be done. On stainless steel, run times can be as long as 3 or 4 hours due to the hardness of the steel. The larger the tank, the shorter the run time because there is more weight on the parts as it goes to the bottom of the tank or bowl.
