This paper presents the technologies for high precision machining with high-speed and high-acceleration driving of feed-axis of double-column machining center. In the proposed approach, linear motors whose stator has no magnet are adopted to the feed-axis. In addition, the force pulsation of linear motor is reduced by arranging of magnets and canceling effects of two sliders. Moreover, we proposed to adopt the feed forward compensation of the mechanical deflection which caused by high-acceleration.
