Gleason Genesis 200 HSD

The Gleason Genesis 200 HSD is a high-speed dry gear hobbing machine built for the production of external spur and helical gears, splines, and worm gears up to 200 mm in diameter. The HSD designation — High Speed Dry — signals its core design philosophy: maximum production throughput using carbide or powder-metallurgy hob cutters in a dry cutting environment, eliminating the cost and handling burden of cutting fluid systems. The Genesis 200 HSD sits within Gleason's Genesis platform, which standardizes the mechanical architecture across multiple hobbing and chamfering models to reduce the learning curve for operators already familiar with Gleason equipment.

Dry hobbing with coated carbide hobs has become the preferred process for high-volume automotive gear manufacturing because it eliminates coolant-related costs (purchase, disposal, temperature stabilization), reduces chip handling complexity, and is compatible with modern TiAlN and AlCrN hob coatings that perform best at elevated cutting temperatures. The Genesis 200 HSD's hob spindle reaches speeds up to 8,000 RPM, enabling carbide hob cutting data that would be impossible with HSS tooling. The work spindle's electronic gearing system synchronizes rigidly with the hob spindle through direct-drive motors, eliminating the mechanical gear trains that historically limited synchronization accuracy and introduced vibration.

The Genesis 200 HSD accommodates single- and double-cut hobbing cycles, shift hobbing to distribute wear across the hob length, and integrated chamfering/deburring via an optional chamfering station on the same machine. Gleason's ProControl software interface simplifies job setup — operators enter gear parameters from the drawing (module, number of teeth, pressure angle, helix angle, face width) and the software calculates hob speeds, feeds, and axial shift parameters automatically. The control also manages automatic hob head swiveling for helix angle changes during changeover.

At approximately $600,000-$900,000, the Genesis 200 HSD competes with the Liebherr LC 180/200 series, Pfauter (Gleason) heritage hobbers, and Mitsubishi GA series gear hobbing machines in the automotive transmission and drivetrain component market. The machine is especially well-suited to shops already using Gleason grinding machines, where common software toolchains and process documentation reduce engineering overhead for the complete soft-to-hard gear manufacturing workflow.
