Electro-Mechanical Pot Broach

Offered in electromechanical or hydraulic styles, these machines can produce various non-helical external profiles such as parallel sided, involute splines or cam forms and various other shapes. Pot machines come in tonnage capacities from 5 to 50 tons and strokes up to and including 78 inches. These machines usually can be installed on a standard concrete industrial floor, however, larger machines such as a 35 ton 78 inch stroke model will require a 12 inch steel reinforced foundation. Pot machines require approximately 400 square feet of floor space and up to 25 feet of ceiling height if equipped with an optional tool change crane.
