MarSurf GD 280

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).

Speedy measurements and changeover

• Very short measuring times thanks to high positioning and measuring speeds (up to 200 mm/s in X and 50 mm/s in Z)
• Z-axis with full CNC-capability for automated operation
• Contact and zeroing across Z-axis in Z+ and Z-
• Quickly change the probe arm without tools thanks to magnetic mount

Flexible and versatile

• Easily switch from standard to perpendicular measurement without a tool or adapter - even for upside down measurements
• 390 mm x 430 mm support plate can hold even large workpieces
• Maximum handling flexibility thanks to support plate with 50 mm bore dimension and plug-in guide stops
• Proven quality and wide range of probe arms from the BFW-250 probe system
• Extensive accessories for maximum flexibility
