D800Z

The D800Z integral, direct-drive motor design of the fourth and fifth axes and highly rigid supporting machine structure deliver productive speed and smooth motion, and ensure outstanding accuracy—even with large workpieces and payloads up to 1,200kg. In addition, core-cooled ballscrews, temperature control of the direct-drive motors and massive machine structure provide renowned thermal stability that guarantees sustained accuracy over time.

The uniquely designed “Z” shape of the tilt-trunnion table ensures that the center of gravity of the table and work are always captured within the center of rotation of the B- and C-axes. Large-diameter bearings minimize table deflection and provide outstanding stiffness and rigidity, regardless of the angular and rotary position of the work. The direct-drive motor design provides the speed for productivity and precision for tight-tolerance work.

The D800Z can be configured with two different spindle combinations: D800Z (CAT40) and D800Z (CAT50). The D800Z (CAT40) offers a standard CAT40 (or optional HSK-A63) 14,000-rpm spindle. As an option, the D800Z (#40) can also be configured with a 20,000-rpm HSK-A63 spindle. The D800Z (CAT40) incorporates a 40-tool magazine. The D800Z (CAT50) offers a standard CAT50 (or optional HSK-A100) 12,000-rpm spindle. As an option, the D800Z (CAT50) can also be configured with an 18,000-rpm HSK-A100 spindle. The D800Z (CAT50) incorporates a 48-tool magazine. The range of spindle offerings provides the ability to customize the machine to suit a wide variety of machining applications. Feedrates of 36,000mm/min. on the X-, Y- and Z-axes, and 18,000 deg/min. (50 rpm) on the B- and X-axes ensure productivity.

The D800Z comes with a two-sided front-door design, for easy access to the spindle and table for setup purposes, and a large window, for enhanced visibility. The machine’s compact size of 3,200mm x 5,070mm x 3,600mm requires less floor space, and its intelligent design facilitates maintenance activities.

Also featured on the D800Z is Makino’s proprietary, next-generation Super Geometric Intelligence (SGI.5) software—developed specifically for high-feedrate, tight-tolerance machining of complex 3-D, contoured shapes involving continuous tiny blocks of NC data, which ensures production rates faster than standard CNC systems, while maintaining high accuracy. SGI.5 helps provide the lowest cycle times and costs achievable by reducing machining cycle times on dies, complex cavities and cores, and aerospace parts by as much as 40 percent, when compared to most other control technologies.

The D800Z is equipped with a number of 5-axis features, including Tool Center Point (TCP) control, which permits programming based on the tool tip, so that tool compensation features can be applied. Further TCP developments improve the cutter path to achieve greater surface quality. Dedicated user-friendly screens are developed to simplify the overall application of 5-axis machining. Easy-to-apply functions are included to prevent interference between the spindle and trunnion during automatic operation, eliminating collisions.
