Cleverly geared

Gear and roughness measurement grow together: a new probe arm unit qualifies the gear measuring system from the MarGear GMX series for the measurement of roughness.

Mahr equips its MarGear GMX gear measuring systems for roughness measurements.

The measuring systems of the MarGear GMX series from Mahr are proven gear measuring stations for high-precision and fully automatic testing of gears and complete gear shafts up to an outer diameter of 600 mm. To expand the tried-and-tested devices, the manufacturer will present a new probe arm unit for measuring roughness at the Control trade show in Stuttgart. By using an inductive probe from the MarSurf range, the measuring stations now also allow for standard-compliant measurement of roughness from Rz 1 μm. With MarWin Roughness it is possible to evaluate almost all standard surface characteristics – for example according to ISO 42878 and ISO 13565-2.
With the new probe arm unit, companies have the opportunity to qualify an existing MarGear GMX measuring station quickly and cost-effectively for new measuring tasks. The successful combination of gear and surface measurement in just one clamping enables companies to reduce their measuring times and, in addition, lower maintenance and investment costs.

New MarWin functionalities available
The proven MarWin software has also been extended with new functions in the area of MarGear: In Version 11, among other things, evaluations and tolerance tables according to AGMA 2000-A88, DIN 5480, GOST, ANSI B92.1 and CAT 1E2028 / CAT 1E4157 are possible. In addition, the new version allows topographies to be measured and evaluated, well-defined feed marks to be determined, and tooth length to be determined using k-teeth (Wpk). A new and very fast method for pitch completes the functions of MarWin for MarGear.
