Gleason offers all types of gear milling cutters, from standard convex and concave radius designs, to the most complex impeller rotor form cutter. Standard gear milling cutters can be designed with either a ground or unground form to produce spur or helical gear teeth, bevel gear teeth, rack teeth and special gear forms. Special gear milling cutters also can be designed to produce a true involute form on the gear teeth. This type of cutter is required if the gear is to roll with a gear hobbed with a standard gear hob. Gear cutters for any pressure angle can be made with the true involute form. Designs include: • Ground and unground forms • Straight helical or angular flutes • Radial, positive or negative rake tooth faces • Gang sections butted together or interlocked • Staggered or intermittent cutting teeth • Radial, axial and undercut clearances
