In this article, CNC linear guides will be analysed, specifically the hydrostatic guideway, which refers to a guideway that does not rely on rolling contact bearings but rather floats on a high-pressure film of oil. This may sound like a step backward on the path to next-generation machining but is in fact on the cutting edge of linear motion.
