Feature
Real Y-axis with BMT Living Turret and Sub-spindle performs multiple tasks on a workpiece and decreases inaccuracy from machining and arithmetic error; Real Y-axis allows to make servo compensation, performs excellent positioning accuracy.
High Rigidity structure design by CAE analysis with quality engineering that has been considered the geometry and the physical properties of the design to increase reliability and material removal rate (MRR) effectively.
The Boxway Type One-piece 30° Slant Bed offers perfect stiffness and lower vibration to deliver much heavier cutting with a smaller footprint.
