Gleason exhibits new large gear production technologies at Wind Power 2010

Apr 30, 2010

Rochester, New York, April 30, 2010 – Wind turbine gears produced by Gleason gear production machines and cutting tools supply over 50% of the world’s wind energy.   That percentage is expected to increase, with introduction of a host of advanced new technologies designed to improve production, quality and cost of even the very largest wind turbine gears.   Visitors to the Gleason booth at Windpower 2010 can learn more about many of these new technologies, including:


•The industry’s most complete line of gear-cutting tools and workholding solutions for large cylindrical gear production.   Gleason is the industry’s leading supplier of cutting tools for the production of cylindrical and bevel gears of all types and sizes.   On display will be examples of the OPTI-CUT® family of indexable carbide-insert milling, hobbing and shaping cutters, designed to reduce windpower gear cutting costs by as much as 50%.  

Visitors can also learn more about Gleason’s complete series of quick-change workholding equipment for large production machines, such as the Gleason  X-Pandisk® fixture system which automatically aligns workpieces weighing up to 2,000 kg to reduce changeover time by up to 70%.


While not exhibited at Windpower 2010, several other significant new Gleason technologies and products will be introduced to visitors, including:


•The Titan® 1200G and 1500G Gear Grinding Machines, capable of a 50% increase in productivity using the POWER GRIND process.  In the Titan gear grinding machines, Gleason has combined exceptional productivity gains with the very high precision required by today’s manufacturers of larger cylindrical gears.  Among Titan’s most important capabilities is its ability to offer users, on a single platform, the greatest possible flexibility for the production of single parts with an advanced profile grinding option and much faster fully-automated large-scale production option of combining profile grinding and threaded wheel grinding using our innovation POWER GRIND process.


 •OPTI-GRIND, delivering up to a 40% increase in productivity.  Significant productivity benefits are possible on new Gleason Profile Grinding Machines utilizing the OPTI-GRIND process.   This breakthrough technology uses multiple grinding wheels (for roughing and finishing) simultaneously at significantly reduced production times.   In addition to the productivity gains inherent in the use of OPTI-GRIND, users also benefit from improved surface roughness as a consequence of using a fine grit size grinding wheel for the finishing cycle.


Complete gear inspection systems.  For complete inspection of gears as large as three meters in diameter, the Gleason GMM Series of Analytical Gear Inspection Systems is a leader in speed, accuracy and ease of operation.

The GMM machines are equipped with GAMA™, and the Renishaw SP80H Probe system, making GMM machine series the most user-friendly inspection system in its class.

The most complete range of  advanced machines for the ‘soft’ manufacturing and hard finishing of the largest cylindrical gears, including hobbing, shaping and profile grinding machines, for gears up to 6 meters in diameter.
