The WGT series

The 4-axis measuring instruments of the WGT series have high-precision mechanics and electronics, which are controlled by smart and user-friendly software. They meet all accuracy requirements regarding gear wheel manufacturing and comply with VDI guideline VDI / VDE 2613, group 1. In addition to the gear inspection machine options available as standard, customer-specific solutions are also available, such as extending the travel range on the Z axis, longer tailstocks to accommodate long shafts and rotary tables adapted to

the payload. An automatic probe changing system ensures uninterrupted measurement of the workpieces and alsooffers the highest levels of convenience for the operator. The extensive software features make the machines suitable for measuring gears such as all types of spur gears, bevel gears, worms, worm gears, shafts, gear hobbing, cutting, and shaving tools as well as rotationally symmetrical parts such as shafts and many more.

Highlights• Highest precision provided by granite guides and

air bearing• Low operating costs due to contactless guides and reliable

probes as well as inexpensive spare parts• Flexible for all types of gears• User-friendly interface and ergonomic design• Manufacturer-neutral GDE-interface for gear data transfer

from different manufacturers of gear inspection machines but also for automatic adjustment of production machines („open Connect“ resp. “Closed Loop”), optional

Software The TMain software supplied by the WGT series consists of the basic functions:• „TGear“ for fully automatic measuring of external and

internal spur and helical gears• “TAlign” for determination and compensation of errors

in axis alignment• “TStylus” for stylus configuration and management

including fully automatic stylus calibration

Additional Software options for inspection of• Involute and non-involute splines• Geometric elements including form and position on shafts• Hobs• Cutting tools• Shaving tools• Face coupling and clutch teeth gear inspection• Worms• Worm wheels• Bevel gears• Calculation of nominal grid points of straight bevel gears• Determining gear data for unknown gears• Racks• Broaches• Female / male rotors, cycloids, sprockets• Root fillet radius scanning
