Mahr Metrology MarGear GMX 275 W

The MarGear GMX 275 W is a high-precision, fully automated gear measuring system for cylindrical and helical gears up to 275 mm diameter, offering fast, reliable, and accurate form and position inspection.

  • Fully automatic gear measurement – minimal operator intervention.
  • Large measuring rangeX: 180 mm, Y: 150 mm, Z: 320 mm, max gear diameter 275 mm.
  • High accuracy – axial runout deviation 0.11 µm + 0.0008 µm/mm, radial runout ≤ 0.11 µm.
  • Heavy workpiece support – up to 60 kg (optionally 80 kg).

Description

The MarGear GMX 275 W is a precision gear measuring machine designed for the automated inspection of cylindrical and helical gears, as well as camshafts and complex 3D geometries. With a maximum gear diameter of 275 mm and a workpiece weight of up to 60 kg (80 kg on request), it combines high-speed measurement with sub-micron accuracy. Its axial runout deviation of 0.11 µm + 0.0008 µm/mm and radial runout ≤ 0.11 µm ensure reliable measurement of form and position tolerances, meeting Accuracy Class I standards according to VDI/VDE 2612/2613 Group 1.

The system’s MarWin software allows users to create programs in Teach In mode, which improves efficiency and reduces operator errors. Additionally, the GMX real-time machine error correction combined with the MarEcon control unit ensures precise movement along the X, Y, and Z axes throughout all measurement sequences. With its robust, space-efficient design (1520 × 621 × 1920 mm, 760 kg) and versatile measurement capabilities, the GMX 275 W is ideal for production, quality assurance, and research applications in industries ranging from automotive to precision machinery.
