The mechanism that one table is put on another, it is called "a serial mechanism", is generally adopted for a XY-table of a high-speed machine tool. However, the XY-table causes some problems ; big oscillation occurred by heavy moving parts of machine and high gravity position. To solve this matter, we developed a new table system "The Differential Slider". The Slider has great characteristic features that we can lighten and slim machine due to no source of power and linear encoder in X direction. On the other hand, the table with no moving part is easy to come under the influence of disturbance. In this paper, we focused on The Differential Slider control by the disturbance observer. According to our experiments, we confirmed the effect of disturbance observer and the availability of the Differential Slider mechanism.
