Claims

[Scope of utility model registration request]

The movable table is gripped by the table guide, a minute bearing gap is formed between the movable table and the table guide, compressed air is introduced into this bearing gap to create an appropriate pressure distribution, and a load is applied to this. In a slide table device that moves a movable table within a short range, an air supply passage is formed in the center of the table guide, and an air supply hole is formed that branches from the air supply passage and opens on the surface of the table guide. and forming a groove on the inner surface of the movable table facing the air supply hole and having a width slightly wider than the diameter of the air supply hole and a length equal to or slightly longer than the movement stroke of the movable table. , an air supply passage communicating with this groove is formed inside the movable table, an air supply passage communicating with this air supply passage is formed along the moving direction of the movable table, and furthermore, several places of this air supply passage are formed. A slide table device characterized in that an air supply hole is formed which branches from the air supply passage and opens into the inner surface of the movable table, and has an orifice at the inner end thereof for restricting compressed air.
