Gleason GP200ES Gear Shaping Machine with electronic helical guide. Based on the worldwide proven Gleason-Pfauter Gear Shaping Machines, a totally new shaping head was developed featuring a backlash-free direct drive for the cutter spindle. With the appropriate software, additional generating cutter rotational motion required for helical gears can be superimposed electronically on the cutter spindle rotation. All gear cutting, tooling and process data are entered via the Dialog Program. The CNC controller calculates all the necessary machine data/settings. These functions are embodied in the “Electronic Helical Guide”.
