Modern milling machines look much the same as they did 25 years ago. However, they now must cut super alloys, titanium, and high tensile steels to closer tolerances and at faster rates then previously. To handle these requirements, the new milling machines provide higher horsepower, greater stiffness, and wider speed and feed ranges than before.

However they now must cut super alloys titanium and high tensile steels to closer tolerances and at faster rates then previously. To handle these requirements the new milling machines provide higher horsepower greater stiffness and wider speed and feed ranges than before. In addition more accurate lead screws closer alignment numerical control NC and computer numerical control CNC all result in faster work with better finishes and greater accuracy than ever before attained.
