The new generation FX-1500 series twin-spindle twin-turret turning center, with diversified configurations, upper and lower turrets can be selected Y-axis or milling function separately. It adopts a 60-degree inclined back base which is designed through finite element analysis and practical experience; therefore, it provides better thermal displacement suppression ability, better chip removal ability and smaller footprint. The upper and lower turret supports double Y-axis configuration which improves the flexibility of the tool position and process arrangement. Moreover, it is equipped with the X and Y axis mixed with the triangular column and the linear box guide rail, which makes the machine with much higher rigidity.
