Pot Broaching Machine

Pot Broaching Machine

Offered in electromechanical or hydraulic styles, our pot broaching machines can produce various external profiles such as parallel-sided, involute splines or cam forms and various other shapes. Federal Broach’s pot machines come in tonnage capacities from 5 to 50 tons and strokes up to and including 78 inches.

Facility Requirements

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.
