The full-mechanical-cam system ATC assures high-speed, accurate tool changes and offers high durability. Combined with the high operating speed of the automatic shutter, the ATC completes a T-to-T process in seconds. The cassette-pot magazine flexibly adapts to system expansion and boasts a top-class tool weight-handling capacity of 25 kg maximum. The variable-speed ATC function changes heavy tools smoothly, while the single-motor system assures complete synchronization of the tool clamp/unclamp operation and high-speed ATC operation.

The direct-turn APC mechanism is designed for lifting and rotating and provides better load capacity. The APC adapts to a multiple APC system, thus providing added flexibility in future system expansion and line configuration.

The machining center is configured with a thick-wall box and high rigidity. While expanding the thickness of the machine body and column and improving the rigidity, the deformation caused by thermal change is controlled to a minimum, ensuring high precision over long periods.
The configuration of the X-axis (moving the column left and right) and Z-axis (moving the table forward and backward) is compact, occupying 30% less space than the previous machining center. It is suitable for machining automobile engine cylinder bodies, large steel components, castings, and aluminum components. The machining center works efficiently and saves space due to its compact configuration.
