Werth-Insight: Mounting air bearings

What are you doing, Mr Fink?

When mounting air bearings, it is important at what distance and in what alignment they are adjusted to the guideway so that the unit axes can later move on the air cushion. On the VideoCheck® FB, we position the air bearing at an exact distance from the granite with the help of ball heads on fine-thread screws (so-called calottes). The air then flows through the finest bores in the bearing. An air cushion is built up and the slider is made to float. I use a dial gauge to determine the so-called flight height, which is very important for the perfect functioning of the measuring machine. The air bearings are also checked by our field service as part of the annual maintenance.

What is your background?

I wanted to do something technical, with my hands, that required skill and offered variety. During my research, I came across Werth and started an apprenticeship as an industrial mechanic specialising in mechanical and plant engineering. My first tasks included assembling small assemblies such as various drives, then I was allowed to assemble more complex assemblies. When my trainer was sure that I knew what to look for, I was introduced to assembling the machines. You start with a ScopeCheck® S and then gradually get to know the different machine types and families. In between, there are always individual orders or special productions, for example for development. Sometimes I'm allowed to help with the installation of the sensors, but you need several years of professional experience for sensor installation.

What do you enjoy most about your work?

I enjoy helping with the assembly of the large TomoScope® L and XL machines the most. But I also enjoy working on the turning and milling machine. There, for example, I manufacture and machine individual parts and accessories for more specialised machines or sensors, such as complex 6-axis machines or our Werth Interferometer Probe WIP. I really hope that I will be taken on according to my apprenticeship and that I will be able to continue to support the production.
