YBM 8T-TT
A critical condition for realizing a high accuracy 5-axis machining is that the center of rotation axis is always constant in space. The 5-axis machine YBM 8T-TT developed on the basis of YBM 8T fulfills this condition, and for high speed and high accuracy machining, the A-axis drive uses a system that controls synchronously both axes of cradle. Further, the trunnion base has an integral construction to improve the rigidity and also the A-axis trunnion is thermally controlled, so that the influence of a cutting reaction force, mass variations, and thermal deformation can be minimized, thus enabling a high accuracy machining by high speed and high accuracy positioning.
