Overview
The Gleason Genesis 260H is a high-performance CNC hobbing machine built for the efficient production of external and internal cylindrical gears, splines, sprockets, and worm gears in automotive and general industrial applications. The Genesis platform is Gleason's answer to the demand for flexible, high-speed hobbing with the process reliability needed in lean manufacturing cells.
The 260H features a direct-drive hob spindle with electronic gearbox (EGB) replacing mechanical change gears entirely, enabling instant setup changes and eliminating a major source of transmission error. The machine's structural design uses a meehanite cast iron base with integrated ribbing optimized through finite element analysis, providing the damping characteristics needed for high-speed dry hobbing operations with carbide hobs.
With a maximum workpiece diameter of 260 mm and a max module of 8, the Genesis 260H is well-suited to medium-duty passenger car and light commercial vehicle transmission gears, as well as industrial gearbox components. The integrated Gleason 300GMS control provides full 5-axis simultaneous motion and supports diagonal shift, climb/conventional hobbing, and automatic tool life management.
The machine is designed for lean cell integration and can be equipped with automatic workpiece loading systems, on-machine gauging, and Gleason's Total Productive Maintenance (TPM) package. Its compact footprint relative to its workpiece capacity makes it a popular choice for automotive tier-1 suppliers managing floor space efficiently.
