Overview
The Gleason GENESIS 210H is a CNC gear hobbing machine for external and internal cylindrical gears up to 210 mm (8.3 in) outside diameter and module 8 (DP 3.2). It is the flagship small-to-medium capacity machine of Gleason's GENESIS hobbing line, optimized for automotive and precision gearbox gear production where high throughput, consistent quality, and flexible automation integration are the design priorities.
The GENESIS 210H uses the continuous generating hobbing process — the dominant method for high-volume cylindrical gear production worldwide. The hob rotates in a synchronized relationship with the workpiece spindle as it traverses the gear face width, generating the involute tooth profile. The machine supports conventional and climb hobbing, radial and tangential infeed, and a full range of hob shift strategies for tool life optimization. Maximum module 8 covers automotive transmission gears, differential side gears, and most precision gearbox applications within the 210 mm envelope.
Gleason designed the GENESIS 210H around a vertical workpiece spindle configuration, which simplifies chip evacuation and improves thermal stability compared to horizontal spindle hobbing machines. The machine's direct-drive workpiece and hob spindles eliminate backlash and gear train errors for improved gear quality. Linear motor drives on the feed axes provide fast, precise positioning with zero wear over the machine's service life.
The GENESIS 210H is designed for integration with Gleason's range of chamfering/deburring modules (Gleason Hurth CBN-based or mechanical deburring) that can be mounted directly on the machine or in a linked cell configuration. This integrated deburring capability — producing a finished, ready-to-heat-treat gear in one setup — is the defining productivity advantage of the GENESIS line over traditional standalone hobbing machines. New GENESIS 210H machines are typically priced in the $600,000–$950,000 range.

Strengths & Limitations
Strengths
- Direct-drive workpiece and hob spindles eliminate backlash and transmission errors, providing better gear quality and lower maintenance than belt or gear-driven spindle designs
- Vertical workpiece spindle configuration optimizes chip fall and evacuation, reducing thermal disturbance from chip accumulation and simplifying coolant management
- Integrated deburring module option produces ready-to-harden gears in a single setup, eliminating a separate deburring operation and reducing work-in-process inventory
- GEMS software provides programmable hob shift strategies that maximize hob tool life across production runs, reducing tooling cost per gear
Limitations
- 210 mm workpiece diameter limit excludes larger automotive and commercial vehicle gears — shops with broader gear size ranges need a larger hobbing platform in addition to the GENESIS 210H
- Gleason GEMS software and tooling ecosystem lock is significant — hob arbors, automation interfaces, and software licenses are Gleason-specific
- Capital cost of $600K–$950K is at the upper end of small-to-medium hobbing machines — justification requires consistent volume of precision gears where quality and automation ROI are clear

Frequently Asked Questions
01
The GENESIS 210H's direct-drive spindles, GEMS software, and integrated deburring capability distinguish it from conventional CNC hobbing machines. Direct-drive eliminates the backlash and thermal growth of gear-driven spindle systems, improving gear pitch accuracy. GEMS provides automated hob shift programming and process optimization. Integrated deburring reduces setup changes and work-in-process. These features are designed for automotive production environments where quality consistency and cycle time matter more than upfront machine cost.
02
Yes, the GENESIS 210H can hob internal gears within its workpiece diameter envelope, using special internal hobbing fixtures and hob geometry suited for internal gear cutting. Internal gear hobbing requires careful hob selection to avoid interference between the hob body and the internal gear blank. Gleason's applications team can evaluate specific internal gear designs for GENESIS 210H compatibility.
03
The GENESIS 210H handles helical gears up to ±45° helix angle through synchronized CNC motion between the workpiece rotation axis (A) and the axial feed (Z) axes. The hob is set at the sum of the hob lead angle and the gear helix angle. All axis synchronization is controlled through GEMS software, and helix angle changes are made through the NC program without mechanical change gears — a significant setup time advantage over older hobbing machines.
04
The GENESIS 210H accepts standard metric and inch-pitch hobs in a wide range of diameters and lengths. Gleason's Fassler and other tooling brands supply GENESIS-compatible hob arbors. Direct-drive spindle compatibility requires hobs to be balanced to appropriate quality grades. Gleason's tooling division can supply engineered hob solutions for specific gear applications, including coated carbide and powder metallurgy HSS hobs for high-speed hobbing.
05
The GENESIS 210H is well-suited for EV transmission and reduction gear production. EV gearbox gears typically require higher accuracy grades and lower noise (AGMA class 11–12) than conventional automatic transmission gears due to the absence of combustion noise masking. The GENESIS 210H's direct-drive spindles and GEMS process control achieve the pitch accuracy and profile quality needed for low-noise EV gears. Subsequent gear grinding (on a separate grinding machine) is typically required for final EV gear quality.
