260H and 400H Gear Hobbing Machines

November 01, 2011

Gleason's Genesis series now includes 260H and 400H Vertical Gear Hobbing Machines for the production of spur and helical gears up to 260mm in diameter, and 400mm in diameter, respectively, and up to 700mm of axial travel to accommodate extra-long shafts.

The new Genesis gear hobbing machines are particularly well-suited for the demands of today's dry machining environment, featuring an exceptionally clean and uncluttered work chamber and a single-piece mineral cast polymer composite base/frame with superior damping and thermal stability. They are also among the most compact machines in their class, with a slim-profile design that makes it easier to both install the machines and integrate all styles of automation for cell/system application, as well as making it faster and more efficient for operators to manually load/unload parts and tooling.

Additionally, users can choose from two direct drive modular workspindle options, two different high-performance hob heads, multiple tool interfaces, quick-change workholding, and integrated rotary chamfering and deburring to greatly improve the productivity of the widest range of gear hobbing applications, whether small batch or automated high-volume production. Like all the Genesis machines, the new 260H and 400H are designed to simplify and make more efficient every operation and maintenance task. They are equipped with the SIEMENS 840D CNC control running the latest Gleason Windows-based software, making them exceptionally user-friendly. All major service components are consolidated in Easy Access Modules to speed and simplify maintenance.

Finally, both machine models are designed to help customers meet the need for greater sustainability with a host of features that greatly reduce energy consumption.
