Gleasons New Threaded Grinder Optimizes Fine Finishing of Hard Spur and Helical Gears
January 2, 2007—Gleasons new Genesis 130TWG High Speed Threaded Wheel Grinder features a new design that reduces floor space requirements and improves cycle times for the finishing of hard spur and helical gears with diameters as large as 130 mm.
The 130TWG Threaded Wheel Grinder is the latest in Gleasons Genesis family of gear production equipment. All of the Genesis machines share a common platform: a single-piece frame cast from an advanced polymer composite material, which can be made faster and with more rigidity than conventional cast-iron assemblies. This platform design also ensures a compact machine footprint and enables the user to install and re-locate the machine with no special lifting equipment or special foundations.
The 130TWG Threaded Wheel Grinder built at Gleason-Hurth in Munich uses ceramic-bonded grinding worms as abrasive tools. Like the larger 300TWG Threaded Wheel Grinder, these grinding worms can be dressed using either diamond dressing wheels or the more flexible Gleason dressing tool. Diamond wheel dressing provides the option of rapid dressing independent of number of starts of the grinding wheel, particularly in the case of high production volumes. For applications mandating more flexibility, the fully automatic dressing unit with conventional dressing technology is used.
The 130TWG Threaded Wheel Grinder is equipped with a new mechanical double gripper loader that is fully integrated into the machine. As a result, non-productive time can be reduced, thanks to extremely short part load/unload times.
The workpiece indexing required for this purpose is carried out by a rapid automatic stock dividing system which reduces changeover times.
The 130TWG also features direct-drive spindle motors, which further reduce non-productive and machining times. Higher acceleration/deceleration rates and increased torque, combined with faster axis motions reduce non-grinding time between cycles and increase overall productivity during machining.
Other features include:
* An Easy Access Service Module that consolidates hydraulics, lubrication and pneumatics into one location.
* SIEMENS controls and the latest Gleason grinding technology software to simplify setup and operation control by running the system in a true Windows
* The machine frame designed in such a way that the lift pump can be set up on either the side or the rear of the machine for connection to the coolant system, thus satisfying any cell/system arrangement.
