The H 900-2300 is designed for large gear milling and hobbing applications. The large H series cuts straight and helical gears; crowned and tapered gears; worm gears; cluster gears and special profiles (such as compressor-type rotors); oval gears; herringbone gears (gears with a double helix); and internal gears. This series can utilise any cutting technology available on the market, from single-cut form milling cutters, to HSS or carbide tools for wet or dry hobbing applications, chamer-hobbing. With the optionally available internal milling head intenal gears can be cut as well.
