ABSTRACT Machine tools require linear guides with high stiffness and damping at high feed rates. At the same time, a high position accuracy is essential. The linear guides used together with linear direct drives in High Speed Cutting (HSC) Machines have to fulfill these premises along with the necessity to support the high normal forces of a direct drive.
