Abstract
There is provided a linear guiding apparatus for a machine tool, the system having both of rapid characteristics of a rolling guide which does not deteriorate the precision of movement, and damping characteristics of a sliding guide which is hardly influenced by the load of a movable body. The feed guiding system includes: rolling guides and for guiding a horizontal movement while receiving the load of a movable body on a bed ; a sliding guide including sliding guide ways and , which extend in parallel to the rolling guides and in vertical directions, and slider portions and which slide on the sliding guide ways; and frictional force setting parts for changing the frictional force between the slider portions and the sliding guide ways, to set the magnitude of the frictional force.
