MarSurf MC 510: Measuring Roughness in the Machine Tool

The MarSurf MC 510 is quickly and conveniently available in the machine tool: If a roughness measurement is required, the machine tool automatically inserts the measuring device from the tool magazine into the spindle like a regular processing tool. Various tool holders are available as interfaces, including types SK 40 and HSK-A 63. As soon as the measuring device is ready, the operator can easily align it using the software-controlled, flexible swivel joint. The measuring movement is performed by the integrated feed drive, with the CNC machine positioning the device at the measuring point.
Robust and powerful
Thanks to its robust design, the MarSurf MC 510 is reliably protected against contamination. The automated process ensures fast measurement of surface parameters and precisely reproducible measurements without operator intervention. There is also no need for expert knowledge of metrology, as it is used without direct intervention. It is also possible to draw conclusions about tool wear, which reduces tool costs.
Ideally suited for automated production processes
The machining processes in the CNC machine remain flexible, since the measuring device is controlled directly; the measurement data is output in NC code. The MarSurf MC 510 communicates wirelessly with the Edge PC via Bluetooth® wireless technology. It also has an OPC UA interface and is closed-loop ready. Finally, the surface parameters are documented fully automatically and securely, with no expert knowledge required.
Overall, the device is therefore ideally suited for automated production processes - regardless of the machine and control system. This is because the MarSurf MC 510 offers reproducible measuring conditions without operator influence – process-reliable, flexible and efficient.
