PROBLEM TO BE SOLVED: To perform simple and reliable control of a shape and besides to reduce size and cost. SOLUTION: This two-surface machining device rotates two surface plates 2 and 8 with a work W arranged on a machining surface 2a (8a) having a machining region between a pair of the surface plates 2 and 8. As a result, the two surfaces of the work W1 are machined. The two-surface machining device 1 is provided with an oscillating mechanism 11. The oscillation mechanism 11 is oscillated in the direction of a plane with the two surface of the work W1 brought into contact with a machined surface 2a (8a). |
