A travel limit detection/control device for a milling machine table driven by a screw rod includes a power input section driven by the screw rod, a reduction/output section coupled to and driven by the power input section, and first and second activating members for cutting power supply to the screw rod. A first travel setting member has a first end coupled to and driven by the reduction/output section and a second end that comes in contact with the first activating member when the table reaches a first travel limit. A second travel setting member has a first end coupled to and driven by the reduction/output section and a second end that comes in contact with the second activating member when the table reaches a second travel limit. Positions of the first and second travel setting members can be adjusted to change the first and second travel limits of the table.
