Carl Zeiss Pty Ltd announces the new ZEISS XENOS, a new range of coordinate measuring machines designed to deliver new dimensions of accuracy and dynamics.
Setting a higher standard in precision, the new coordinate measuring machine, ZEISS XENOS features length measurement error of just 0.3 micrometres and will be used for applications that require maximum accuracy, such as in reference labs.
Konrad Werner, ZEISS XENOS Product Manager explains that all standard measuring machines can only be optimised up to a certain level. However, the ZEISS XENOS uses innovative technologies and materials to offer a measuring range of just about one cubic metre. The engineers at ZEISS took a new approach in the development to set a new standard in precision with this measuring volume, while also increasing the measuring speed. Together, the weight reduction and constantly moving masses enable optimal coordination of the drives regarding acceleration and maximum speed.
Unlike other systems, the ZEISS XENOS uses linear drives on all axes instead of friction drives. Werner says it provides clear benefits such as very fast acceleration and generally high speed, as well as high positioning accuracy and shear force-free drives. Taking into account the high-resolution scales on ZEISS XENOS, the new drive technology results in very high path adherence and extremely high positioning accuracy clearly below 100 nanometres.
One benefit of the very high path adherence is evident when measuring curved surfaces; Werner says the more reliably and accurately a stylus follows the specified path, the more precisely errors can be determined.
ZEISS has used for the first time, an innovative silicone-carbide ceramic for the parts of the machine structure relevant to accuracy. Unlike the white standard ceramic, the black silicone-carbide ceramic exhibits around 50 per cent lower thermal expansion, up to 30 per cent higher rigidity and 20 per cent less weight. Compared to steel, it delivers twice the rigidity at half the weight.
A key innovation in the ZEISS XENOS coordinate measuring machines involves the enhancement of the ZEISS VAST gold reference probe and its optimal integration for better accuracy and repeatability.
