The Waterbury Farrel Body/Mouth Annealing Machine anneals only the specific body area or neck and mouth of the pre-formed or fully-formed rifle cases. Cases/case components are fed into the machine, and carried single-file through induction heaters, where the water-cooled generator provides the excitation for the induction coils. The machine provides individual rotary motion to each case while passing through the linear feeding system of the annealer. Finally,  air-cooled cases/case components are ejected.
