Gleason 400H 'recertification' program.
This 400 mm-class CNC hobber carries forward the Gleason legacy of rigid construction and forward-looking engineering. High-speed capability, robust castings, and modern design principles give it the backbone to fully exploit today’s—and tomorrow’s—cutting tool technology. The PHOENIX 400GH keeps its footprint compact without compromising rigidity, accuracy, or serviceability, and its use of standardized, globally supported components helps ensure quick delivery, lower maintenance, and minimal spare-parts burden.
Built-in thermal stability and Gleason’s mature CNC software platform deliver excellent accuracy and repeatability while keeping operating costs in check. The machine supports both wet and dry hobbing and handles high-speed steel or carbide tooling with ease.
Gleason’s CNC hobbers have long been benchmarks in the industry; the 400GH builds on that lineage. It’s engineered for straight spur and helical gears, pinions, splines, worm gears, and similar profiles up to 400/450 mm (15.75/17.72 in) diameter, 525 mm (20.67 in) face width, and 2.5 DP capability.
The machine is equipped with a FANUC 150MB control featuring color CRT, conversational English dialogue, and automatic setup across six controlled axes, with all parameters available in inch or metric.
This 400GH is currently on the floor at Machine Tool Builders in Machesney Park, IL. It is expected to be under power and available for demonstration—and ultimately shipment to a client—near the end of July 2026.
The machine features a functional ring loader with load / unload door to the right of the operator station. Machine Tool Builders can configure a new conveyor, lifting station and alter the enclosure to suit all of your requirements.
