Mahr Equips Gear Measuring Systems with Surface Roughness Measurement

The Mahr MarGear GMX gear measuring systems offer proven, high-precision, fully automatic testing of gears and complete gear shafts up to an outer diameter of 600 mm. At the Control exhibition in Stuttgart Mahr presented the addition of an inductive probe arm unit for measuring roughness on the MarGear GMX. By using the inductive probe from the MarSurf range, the measuring stations now also measure roughness from Rz 1 μm. With MarWin Roughness it is possible to evaluate almost all standard surface characteristics according to ISO 42878 and ISO 13565-2.

The combination of gear and surface measurements in just one part clamping enables companies to reduce their measuring times and investment costs. The new probe arm unit also provides users the opportunity to update an existing MarGear GMX measuring station cost-effectively.

The proven MarWin software has also been extended with new functions. Version 11 adds evaluations and tolerance tables according to AGMA 2000-A88, DIN 5480, GOST, ANSI B92.1 and CAT 1E2028 / CAT 1E4157 . 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) along with a very fast method for pitch.

Mahr has also extended the GMX range with the additional of the MarGear GMX 600 W for measuring crankshafts, drive shafts, gears, camshafts and pistons.
