Guide device, precision support for a linear rail and adjusting method

A precision support (100) for receiving a guide device of a base body (3) of a machine tool, comprising

• a plurality of exchangeable support bodies (1;
• 2) which form support sections for contacting the guide device and are positioned on said base body (3) along a guide axis of the guide device;
• wherein the support bodies (1;
• 2) each have a first support surface for contacting the guide device and a second support surface for contacting said base body (3) and the support bodies (1;
• 2) are provided for tolerance compensation between a bearing surface of said guide rail (LF) and a contact surface of said base body (3), and
• wherein the plurality of support bodies (1;
• 2) comprise horizontal support bodies (2) and vertical support bodies (1) and the horizontal support bodies (2) are provided spaced apart from and in parallel to one another along a horizontal contact surface of said base body (3) and the vertical support bodies (1) are provided in parallel to one another along a vertical contact surface on said base body (3).

A method for adjusting the position of a guide rail of a guide device for a machine tool, the guide device including a base body (3) having at least one contact surface, a guide rail (LF) having at least one bearing surface and a guide axis, and a plurality of exchangeable support bodies (1;

• 2) for positioning said guide rail (LF) on said base body (3), the support bodies (1;
• 2) being arranged along the guide axis for setting defined distances between the bearing surface of said guide rail (LF) and the contact surface of said base body (3), the method comprising:
• adjusting the position of said guide rail (LF) to a predefined position by adapting the shape of at least one support body (1;
• 2) to an adapted shape and/or by replacing at least one support body (1;
• 2).

A method for adjusting the position of a guide rail (LF) on a base body (3) of a guide device for a machine tool, the guide device including a base body (3) having at least one contact surface, a guide rail (LF) having at least one bearing surface and a guide axis, and a plurality of exchangeable support bodies (1;

• 2) for positioning said guide rail (LF) on said base body (3), the support bodies (1;
• 2) being arranged along the guide axis for setting defined distances between the bearing surface of said guide rail (LF) and the contact surface of said base body (3), the method comprising:
• determining the position of said guide rail (LF) at a measuring position with a measuring probe, and
• adjusting the position of said guide rail (LF) to a predefined position by adapting at least one support body (1;
• 2) at the measuring position to an adapted shape and/or by replacing at least one support body (1;
• 2).
