Renishaw Encoder Improves Positional Accuracy for CNC Optical Maker

When a leading manufacturer of CNC optical manufacturing technology needed ultra-accurate and stable positioning for a new system to measure conformal optics, it turned to ABTech Manufacturing Inc., specialists of custom- made ultra-precision air bearings and motion systems. In order to meet tighter customer specifications for positioning resolution, ABTech found the solution in high-resolution linear and rotary optical encoders from Renishaw. ABTech created a five-axis optical measurement platform featuring three of its linear air bearings, two of its rotary air bearings, and Renishaw’s ultra-high accuracy SiGNUM(TM) series linear and rotary encoders.
