Below is a list of Vibratory Tumbler manufacturers from Chelsea, Michigan. Vibratory tumblers are barrels or drums that function by agitating materials in a side-to-side motion at high rates, creating friction and continuous grinding between the vibrating parts or deburring materials. The friction enables the parts tumbler to polish, finish and/or deburr, which refers to the removal of unwanted extra materials called burrs. Most often used as a type of polishing machine, vibratory tumblers are one of the two main types of tumbler used in deburring applications. The other main type of deburring machine is called a rotary tumbler.
