- Encoder RESOLUTE UHV with RTLA scale in FASTRACK guides and with self-adhesive RTLA-S scale
FASTRACK is Renishaw´s revolutionary linear encoder linear fastening system in guides that combines accuracy of ± 5 μm/m with strength of stainless steel and quick and easy installation of the encoder system.
FASTRACK system allows quick disassembly and replacement of the scale even in conditions of limited access, which makes it very convenient for large machine tools, separated into parts for transportation to the final installation site, or in places of damage risks.
FASTRACK system is designed for applications where a high-precision, easily removable scale is required, and consists of two miniature but sturdy guides. These guides securely hold Renishaw´s new thin scales (with a cross-section of 8×0.2 mm) and allow unimpeded expansion of the scales with their own coefficient of thermal expansion; with virtually no hysteresis. For example, the hysteresis value in the case of a 2-meter axis clamped in the center is the fraction of micron within the entire operating temperature range. A damaged large-scale tape can be pulled out of the guides and replaced quickly, even in conditions of limited access, which reduces the machine´s downtime.
The maximum length of the scale currently produced is 10 m.
