Blind Spline Broaching Machine

Blind Spline Broaching Machine

Offered in electromechanical or hydraulic styles, Federal Broach’s blind spline machine produces internal and external blind spines in an array of sizes and part styles. With a wide range 5-50 ton force capacity, 10-13 inch stroke capacity, and 6-26 station rotary table capacity (part design dependent), this turnkey broaching machine is a highly versatile and highly capable asset to your production line.

Facility Requirements

Typically, our relatively compact blind spline broaching machines require only 400 square feet of floor space, 12 inches of reinforced concrete, and a maximum machine height of 17 feet.
