"Even in moderate climates, it is not uncommon for the temperatures in production areas to exceed 30°C," says Johannes Möhrle, Product Manager at ZEISS. Increasingly compact, modern production lines equipped with heat-generating machine tools contribute to room heating. However, limitations in air conditioning can also falsify the measured values on a coordinate measuring machine, e.g. as a result of gust-like air flows. Because heat and temperature fluctuations can impair the accuracy of measuring machines, quality assurance is faced with additional challenges.
Improving air conditioning is one solution, but operating and maintaining such systems is expensive. "This is what led us to enhance our ZEISS DuraMax compact coordinate measuring machine," states Möhrle. The machine works as reliably as before at a temperature range that has more than doubled: ZEISS DuraMax High Temperature & Gradients (HTG) delivers accuracy down to 3.2 µm at ambient temperatures of 15-40°C.
