Bridge CMM designed for job shops
Coord3 Metrology has introduced the bridge-type Ares XL CMM, designed to meet the needs of typical job shops. It features an accommodating measuring envelope, high accuracy, and automated Renishaw touch or scanning probe heads.
The CMM features an ultrarigid alloy platform with a silicon carbide Z-axis column and an integral dovetail X axis machined directly into the granite plate. The bridge beam is an FEA-designed alloy extrusion providing the optimum moment of inertia for minimum deflection when operating at high accelerations, the company states.
Rigid air bearings are applied on all axes with wide bearing spread ratios. The machines have 0.1-µm resolution measuring scales that use dynamic signal processing to provide subdivisional error of better than ± 30 nm.
A pneumatic vibration isolation system is provided, as well as a wireless CMM thermal compensation system of both machine and part that is built into the machine structure, allowing the measuring system to compensate automatically and dynamically for changes in the CMM operating environment.
