ABSTRACT:
In a machine tool having cooperating first and second slides slidably with respect to one another, an improved way damper has a damper plate carried by the first slide in slidable engagement with the second slide, and the plate is retained so as to permit slight movement of the plate in a normal direction to the movement of the first and second slides. A sealed damping chamber is formed between the damper plate and the first slide, having a viscous medium within the chamber which effects squeeze film damping as the damper plate and first slide undergo relative vibratory motion. An alternate embodiment employs a visco-elastic medium in the damping chamber to effect damping.
