SURFACE PRESSURE REDUCING METHOD FOR V-V ROLLING GUIDE

PROBLEM TO BE SOLVED: To reduce surface pressure of a V-V rolling guide by providing a movable body which is fitted to the V-V rolling guide of a stational body and moved along the V-V rolling guide, and blowing out compressed air from the movable body or the stational body near the V-V rolling guide. SOLUTION: A stational body 10 like a bed has a V-V rolling guide 11. A table 12 as a movable body fitted to the V-V rolling guide 11 to be moved in the vertical direction to the paper surface. Compressed air is blown out from the table 12 as indicated by an arrow (a) near the V-V rolling guide 11 to float the table 12 with respect to the bed 10, thereby reducing surface pressure applied to the V-V rolling guide 11. Though the description deals with the example in which the compressed air is blown out from the table 12, it is not limited to this, but it may be blown out from the bed 10. Thus, the surface pressure applied to the V-V rolling guide is reduced by buoyancy produced by the compressed air.
