PURPOSE:To enable a large work to be worked with high accuracy by providing a plurality of wheels pivotably mounted individually left and right to the advancing direction and drive units or the like for driving the left and right wheels individually. CONSTITUTION:A wire electrode supply car 1 and a wire electrode recovery car 2 mount a plurality of wheels 3, 3' and 4, 4' made of magnetic material and are adsorbed to a workpiece 21 by the magnetic force of these wheels and moved. And one side wheel 3 and the other side wheel 3' to the proceeding direction of said car 1 are independently driven by drive units 5, 5' respectively, and the wheels 4, 4' of said car 2 are driven independently by drive units 6, 6' respectively. Thus, a cutting apparatus is provided which can work a large work with high accuracy. |
