OptoScan X

Semi automatic linear measurement station

The OptoScan X-500 device is fitted with an automatic high-precision x-axis. The sensor is moved in a linear direction and provides continuous roughness measurements. With this system configuration quality assurance for piston rods, semi-finished goods and linear movements is easy, fast and economically feasible.

OptoSurf will manufacture prism fixtures customized for the types of goods to be measured. Setting tolerances and adjusting measurement programs is easy with the software. Whether an automatically robot-loaded solution or a stand-alone solution is required – the OptoScan X series is ideally suitable for quality control.

Measuring in the shop floor environment

Damper piston rods measured in the functional detection

To measure a piston rod, the part is placed on prisms and the measurement is started. The sensor moves in a linear direction along the preset surface line at a speed of 100 mm/sec, meanwhile recording 1,024 individual measurement points. Roughness information is gathered over the whole functional area and can be used to monitor the finishing processes. Monitoring takes place directly next to the finishing machine.

Piston rods can be ground and finished in two different directions. One main benefit of the sensor’s design when measuring piston rods is its ability to detect isotropy attributes resulting from grinding directions on the surface, by rotating the sensor.

Form deviations of high-precision linear movements

Grinding sporadically creates process-related chatter marks on linear movements, leading to noise emissions or premature wear. The OptoScan measuring device detects waviness on the movement and analyses the signal, based on the fast Fourier transform.

Waviness with amplitudes < 0.02 µm can be detected. Simultaneously, roughness is automatically measured in the functional orientation.
