Universal, fully automatic optical shaft measuring system

The MarShaft Scope 250 is our compact system with many advantages:

•  High-resolution CMOS matrix camera enables live image on the display
•  High accuracy for diameter and length measurement
•  Extremely short measuring times due to high measuring speeds up to 200 mm/s

 MarShaft Scope 600 plus 3D offers even more by combining optical and tactile measuring technology.

Maximum flexibility and highest precision for your form measurement

• Detection of form, position, roughness, contour and lead in only one measuring sequence
• Universally applicable for workpieces from a few mm in size up to 80 kg
• Highest axis accuracy even with decreasing tolerances
• Reliable repeatability even with difficult measuring tasks
• Fully automatic alignment of workpieces by centering and tilting table
• Shorter floor-to-floor time and thus higher productivity

Automated operation for more productivity

The MarForm MMQ 500 has unique features that make it particularly efficient. This gives it a clear productivity advantage over comparable machines on the market. Thanks to the flexible machine layout, you can choose from eight versions the customized solution that best suits your individual form measurement requirements.

Fully automatic centering and tilting table

Mahr has newly developed the centering and tilting table with a diameter of 300 millimeters. Benefit from its advantages:

• Fully automatic operation
• Fast and at the same time optimal alignment of the workpiece to be inspected
• No manual adjustment – no alignment errors

Fully automatic probe arm unit

The special probe arm unit also qualifies the MarForm MMQ 500 form measuring machine for automated operation:

• Up to four probe arms integrated
• Software-controlled changeover without operator intervention
• This saves time and ensures process reliability

The flexible, fully automatic product family for form and position measurement

• Measuring axes with high running smoothness and precision make a wide variety of measuring tasks possible.
• MarWin software ensures advanced applications such as roughness, waviness and contour measurement.
• Mechanical bearing is up to 70 times stiffer than air bearing and thus contributes to the measuring accuracy.
• Use is possible on the shop floor or in the precision measurement room.

The close-to-production 3D measuring station – ultra-precise and universal

• Measure contour, roughness, offset, runout and tilt errors of optics in one clamping operation
• Especially for spheres, aspheres, cylindrical lenses and freeforms
• Automated, fast and close to production measurement in 2D and 3D
