Gleason’s new Genesis™ 130TWG High Speed Threaded Wheel Grinder features a revolutionary new design that significantly reduces floor space requirements and greatly improves cycle times for the finishing of hard spur and helical gears with diameters as large as 130 mm.
The 130TWG is the latest in a new family of gear production equipment from Gleason called Genesis™. 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 inherently more rigidity than conventional cast-iron assemblies. This platform design also ensures a small, compact machine footprint and enables the user to install and relocate the machine with no special lifting equipment or special foundations.
The 130TWG, built at Gleason-Hurth in Munich, uses ceramic-bonded grinding worms as abrasive tools. Like the large 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. Where demand for flexibility is significant, the fully automatic dressing unit with conventional dressing technology is used. This means that the 130TWG can be universally adapted to suit different customer requirements.
The 130TWG is equipped with an innovative new mechanical double gripper loader fully integrated into the machine. As a result, costly non-productive time can be cut to a minimum, 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 further 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 significant features include:
• an Easy Access Service Module that consolidates hydraulics, lubrication, and pneumatics into one location.
• the latest Siemens controls and Gleason grinding technology software to render setup and operation control easy and intuitive by running the system in a true Windows environment.
• 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.
