Description

What is TONiC UHV?

TONiC UHV brings Renishaw's super-compact, non-contact encoder system to Ultra-High Vacuum applications offering customers improved motion control.
TONiC offers speeds up to 10 m/s and, combined with the Ti interface, resolutions down to 1 nm for both linear and rotary applications. TONiC systems are quick and simple to install with wide set-up tolerances and calibration at the push of a button. TONiC's dynamic signal processing gives improved signal stability with ultra-low Sub-Divisional Error of typically <±30 nm to help realise superior motion control performance.

What is REXM20 ring?

REXM20 is a one-piece stainless steel ring with 20 µm pitch incremental graduations marked directly on the periphery, featuring the IN-TRAC™ optical reference mark. Its larger cross-section allows for the reduction in all installation errors apart from eccentricity, which is easily corrected using a DSi (Dual Signal Interface) and two readheads. Featuring total installed accuracy up to ±1 arc second, zero coupling losses, and exceptional repeatability.
