Gleason Introduces The 300TWG Threaded Wheel Grinder

Rochester, New York, February 12, 2007-- Gleason's latest addition to its line of advanced, highly productive grinding machines is the 300TWG Threaded Wheel Grinding Machine, designed to deliver the industry's fastest floor-to-floor times for grinding of cylindrical gears up with a diameter up to 300mm.

The new 300TWG uses high-speed direct-drive spindles and advanced Siemens CNC controls with Gleason software to take full advantage of the latest multi-start grinding wheels. Multi-start grinding wheels are capable of improving production rates up to 5 or 10 times that of conventional single-start wheels.

In addition, the 300TWG can be equipped with a patented Gleason diamond-plated master dressing gear system that can dress a multi-start grinding wheel in a very short time regardless of the number of starts, making it ideal for higher volume production environments.

Users also have the option of applying a compact, fully automatic CNC dressing unit located just above the grinding head for conventional dressing with diamond plated dressing discs. This is the optimal for the smaller batch requirements of job shop or prototype production.

Also the 300TWG is offered with an optional high-speed, fully automated 2-station ring loader, with easy integration of a spin-dry station if needed.

The 300TWG provides exceptional rigidity for a grinding machine, derived from the use of the standard Gleason hobbing machine base - a proven design that provides significantly enhanced stiffness and stability as compared to other conventional grinding platforms.
