DOUBLE COLUMN MACHINING CENTER

·        20,000rpm built-in spindle

·        2-axis carried by KESSLER in Germany, Max. rigidity and Min. exterior dimensions designed to ensure the processing flexibility, reduce interface with the workpiece.

·        A, C-axis drive mechanism is used D.D permanent magnet motor design, without the traditional mechanical transmission and backlash caused by worm gear, A-axis positioning accuracy up to +/-5 SEC, C-axis positioning accuracy up to +/-3 SEC.

·        Spindle head is balanced by two self-aligned hydraulic cylinders, spindle locates at the center of the two counter balancing cylinders, Z driving ball screw and spindle head, such optimal design to reduce the unbalance force to minimum and to ensure accurate positioning for years.

·        3-way bed (X-axis) design is composed of 3 roller type linear ways. This design enlarges the table dimension to improve the loading capability, to keep high dynamic level accuracy, and to provide the best feeding rigidity.

·        Guide ways are designed with optimal span to carry the table, box-shape bed with strong V-shape enforced ribs allows heavy work piece load.

·        One piece casting with square shape headstock leads spindle to be close to the Y Guide way reduces the unbalanced force to minimum, provide better heavy cutting ability.

·        The best center-line layout of spindle system, spindle is close to the Z guide way, reduce the unbalanced cutting moment and offset of thermal expansion to minimum.

·        Y-axis ball screw is driven through gear ratio 2:1 timing belt, and X-axis ball screw is driven by gear to ensure torque transmitted, and spindle of Z-axis is driven directly (for box way) to create higher acceleration/deceleration rate of the feeding system.

·        Self-alignment twin hydraulic counter balance cylinders with quick response air accumulator design provides smooth and fast acceleration/deceleration of the Z axis movement.
