MarSurf GD: The new reference measuring station for roughness and waviness measurements

The new Mahr measuring stations from the MarSurf GD series are setting new standards.In addition to surface roughness evaluations, profile, and waviness evaluations can also be performed. The new MarSurf GD series is enabling production companies to achieve a new dimension to reliably ensure and improve the production quality of workpieces in the measuring room or close to the production area.
 
The new measuring station concept combines speed, security, and flexibility. The aim is to increase the cost-effectiveness of the system for your company.

The measuring stations are operated with the user-friendly MarWin software (MarWin EasyRoughness or MarWin ProfessionalRoughness).

Innovative technologies:


Fast axes
  • Positioning speeds up to 200 mm/s in X
  • 40 x faster than its predecessor MarSurf GD 120
  • The Z-axis is fully CNC-capable by default
  • The Z-axis is approx. twice as fast as previous Mahr Z-axes
  • Up to 5 times faster than standard Z-axes on the market
  • Contacting and zeroing via the Z-axis

New flexible probe system mount with BFW probe system
  • Simple probe arm change and probe arm protection by means of magnetic probe arm holder
  • Probe arm holder allows the change from standard to transverse measurement without tools or adapters
  • Extensions for the touch probe are possible

Innovative workpiece clamping system
  • Mounting plate 390 x 430 mm with bore dimension 50 mm
  • Integrated 60 mm TY adjustment
  • The combination of mounting plate and integrated TY adjustment makes an additional XY table superfluous
  • Low workpiece setup supports a favorable short measurement loop, which has a positive effect on the measurement results
