Renishaw High-Speed 5-Axis CMM Announced

Published: Wednesday, May 11, 2005 - 22:00

Renishaw recently released Renscan5, a new technology that allows highly accurate, ultra high-speed five-axis scanning measurement on CMMs; and REVO, a series of revolutionary head and probe systems that, according to the company, will redefine the industry. Renscan5 allows the development of a range of breakthrough five-axis scanning products that will measure at speeds up to 500 mm/second, virtually eliminating the measurement errors normally associated with existing three-axis scanning systems. A five-axis system achieves this by allowing the lighter measuring head to perform most of the motion during inspections, which minimizes the dynamic errors caused when moving the larger mass of a CMM structure. Renscan5 will be available with Renishaw’s new UCC2 universal CMM controller.

REVO is the first product to take advantage of the Renscan5’s technology. The series uses synchronized motion when scanning to quickly follow changes in part geometry without introducing its own dynamic errors. This allows the CMM to move at a constant velocity along a constant vector during measurements. The REVO measuring head features ultra-stiff spherical air-bearing technology in each of its two axes, which are driven by state-of-the-art brushless motors that are linked to 0.08 arc-second high-resolution Renishaw encoders, giving fast ultra high-positioning accuracy.
