The CMU Ultra Coordinate Measuring Machine is a high-end measuring tool produced by TZTEK. With a unique single-sided overhead structure, and advantages of stable and reliable performance, high efficiency and high precision, it can cover most application scenarios for triggering and scanning complex measurement.

• Stable mechanical structure. The single-sided overhead moving bridge design reduces moving
mass and brings the drive closer to the moving center of mass, which minimizes Abbe error, and effectively improves motion performance and accuracy stability.

• High-rigid high-performance air-bearing guides brings neither friction nor wear or tear, and the three axes are designed in an enveloping structure together with air-bearing pressure monitoring effectively ensure its stability.
​
• Ultra-low linear temperature and linear expansion coefficient scales for three axes is insusceptible to
temperature change, effectively improving the accuracy of the machine.
​
• Application of new materials. Key structural parts are made of high-precision silicon carbide  ceramics, which provide higher rigidity and lower temperature linear expansion performance while making the moving bridge lighter in mass, greatly improving accuracy and long-term reliability.
​
• Safety. The Z-axis is under the protection of both the pneumatic logic of the balancing cylinder and the hardware hold-up mechanism, ensuring the safety of the sensors in an emergency.
