Renishaw has more than doubled the maximum length of its RTLA linear stainless steel ribbon scale. It is now available in lengths up to 21 metres and can be used with or without the Fastrack scale carrier system. The longer RTLA scales, used with Renishaw’s Resolute absolute optical encoders, are now suitable for applications with very long axes. These include large aerospace trimming and drilling systems, wing structure drilling systems, milling machines for power turbine manufacturing and the manufacturing of outsized components.
Renishaw’s Resolute is said to be the world’s most advanced single-track true-absolute optical encoder system delivering up to one nanometre resolution, superior long-term reliability, instant operation after power-up without reference return, high speed performance to 100 m/s, smooth velocity control with interpolation errors (SDE) of ±40 nm and excellent positional stability with jitter (noise) of 10 nm RMS. RTLA scales are mounted to the substrate using either their own self-adhesive backing or the Fastrack scale carrier system. Comprising two miniature guide rails, Fastrack securely retains Renishaw’s low-profile stainless steel scales and allows them to expand at their own coefficient of thermal expansion.
