Mahr Metering Systems

Automated measurement thanks to robot loading
Mahr Engineered Solutions (MES) has developed a cost-effective solution for automating recurring measurements. A collaborative robot loads measuring stations in the measuring room or production shop without an operator, which significantly increases the degree of utilization of the measuring station and drastically reduces overall costs.

The system consists of a workpiece storage unit with pull-out magazines containing the parts to be measured. The MarSurf measuring station stands on the workpiece storage unit; a robot arm is tethered to the side so that it can easily access the magazines. The robot pulls one out and removes a component using the gripper, which was made to fit precisely in 3D printing. It then places it on the workpiece holder of the MarSurf device, and the measurement is started automatically. After successful measurement, the robot puts the part back into the workpiece memory.

Lösung with numerous benefits:

• Customers benefit from many advantages with this system:
.
• It requires only as much space as a standard measuring station.
• No personnel are tied up at the measuring station.
• Only for reloading the magazines an operator is necessary.
• The useful life of the measuring device increases, even three-shift operation is möglich.
• Depending on the application, even simultaneous loading and measuring is möglich.
• The robot can be reprogrammed very easily and quickly for other workpieces, making it flexible to use.
• Overall, the throughput thus increases, while the costs decrease.

Technical details:
- Workpiece weight 5 kg incl. Gripper
-Up to 10 drawers
- Individual design of the drawer inlay
- Fully automatic sequence, even as an unattended night shift. Translated with DeepL

Powerful confocal microscope with ultra-fast image acquisition thanks to specially developed and patented multi-pinhole technology
Independently of surface properties, measurements are taken with high edge acceptance and dynamics – thanks to HD stitching with constantly high resolution even on large surfaces with maximum robustness. The MarSurf CM explorer is a compact and user-friendly complete package for precise measurement and analysis of surfaces. The measuring system is fully equipped with HDR function, automatic lens detection and collision detection in all spatial directions. It is characterized by its economical use in the laboratory as well as for quality assurance in the production environment.

With the cylinder coordinate measuring machines of the Mar4D PLQ 4200 series we offer you a powerful measuring solution for complex rotationally symmetrical workpieces. Thanks to multi-sensor technology, these cover a particularly wide range of dimensional measuring tasks. In addition, the machines are robustly designed and thus ensure measurements directly in production; this means shorter throughput times and thus increased throughput as well as extraordinary productivity. In addition, they are equipped with a
motorized abutment and can thus also adjust workpieces between centers. The standard equipment also includes a form tester C-axis. This ensures highly accurate roundness and concentricity measurements with deviations of 40 nm.

The outstanding feature of this year's Mar4D PLQ 4200-T4 variant is the newly developed fully automatic centering and tilting table. It aligns workpieces that are not manufactured and measured between centers in the shortest possible time and with micrometer precision, for example from 4 mm to 1 µm in just 30 seconds.
This makes this method far superior to the purely mathematical correction of alignment errors. Translated with DeepL
