The structure for symmetrically disposed linear motor operated tool machine comprises two parallelly erected sustaining walls, a movable gantry, a sliding saddle, a tool spindle, and a weight compensation device. At both sides of the movable gantry between the sustaining walls, between the gantry and the sliding saddle, and between the tool spindle and the sliding saddle, a pair of linear motors is symmetrically disposed such that the armature reaction between the winding and magnet is compensated each other by the opposite one therefore any possible deformation force to the tool machine structure is eliminated.
