Guess I would need the ability to do both, so cutting helical gears is useful, but without the ability to cut the internal splines, its kinda of useless. Mitre gear. A helical gear such as shown in Figure 6-6 is a cylindrical gear in which the teeth flank are helicoid. Both internal and external splines can be cut using our gear cutting machines, including internal straight spline and external straight and helical splines. In contrast, the regular helical gears are sometimes called single helical gears. In other words, the teeth are cut into the inside diameter while the outside diameter is kept smooth. Internal helical broaches can be developed, designed, built and tested for a wide variety of parts, utilizing annular or spiral gullet design. External, internal, straight and helical gears as well as special profiles; GIS Special machine Soft finishing of internal threads in ball screw tracks or similar profiles; Prototype production; Non … Also, they offer higher efficiency, higher load capacity, and correction of profile and … The rotations of the cutter and the workgear are in opposite direction for external gear and in same direction for internal gear.
