How can hydrostatic guideways take your machining to the ...

Due to the high rigidity possible, improved accuracy with movements of 0.1 microns is possible. Due to the oil film, the stick-slip phenomenon that is ever-present in roller contact guideways is also eliminated due to there being no physical contact between carriage and rail. This further improves accuracy by ensuring smooth motion at any speed.
