BROACH MACHINES
Internal Broach
Offered in electromechanical or hydraulic styles, rising table or pull down versions. These machines can produce various internal profiles such as parallel sided, involute splines, cam forms and various other internal profiles. Internal machines come in tonnage capacities from 5 to 60 tons and strokes up to and including 120 inches. Smaller machines usually can be installed on a standard concrete industrial floor, however, larger machines such as a 25 ton 100 inch stroke models will require a 12 inch steel reinforced foundation. Internal machines require approximately 300 square feet of floor space and up to 25 feet of ceiling height if equipped with an optional tool change crane. Exact specifications will be supplied due to the large variation of machines offered in this style.
