Fibre scanner production

What are you doing, Mr Mandler?

I produce the fibres for our patented Werth Fiber Probe® micro-probe. To do this, I enter the required parameters in the software, such as the probe ball diameter, shaft length and shaft diameter. Then I roughly cut the glass fibres to the right length and clamp them in the specially developed fibre drawing stand. There, electrodes are used to generate a plasma in which the fibre is heated and drawn into the preset geometry.

What is your background?

My father introduced me to Werth Messtechnik back then. I initially completed a one-year internship in assembly for my vocational baccalaureate. I then started an apprenticeship as an industrial mechanic in 2014. According to my apprenticeship, I was taken on and employed in the bridge-type machine assembly department. When my predecessor in fibre production retired, I was given the opportunity to take over his work.

What do you enjoy most about your work?

The fibres have different geometries, including dual-sphere probes. With prototypes, I have to experiment for a while to find the right parameters. It's always interesting to see how the fibre drawing stand reacts when I adjust the length specification and heating values in the software. I also have to take the material for the stylus tip into account when setting the length. With prototypes, for example, it can happen that the geometry corresponds to the specifications, but the fibre is 300 µm too short. For us, it's always a matter of micrometres!
