Makino Unveils D300 5-Axis Vertical Machining Center

By DE Editors

Makino has released the D300 5-axis vertical machining center. Similar to the company's D500, the 5-axis machining center is designed specifically for small, complex, 3-D contouring of high-quality part production, like that required in aerospace machining, medical manufacturing, high-end job shop and die/mold applications.
 
The D300 worktable offers a work area diameter of 300mm, accommodating workpiece sizes up to 450mm by 270mm and 120kg. The machine provides X-, Y- and Z-axis travels of 300mm, 500mm and 350mm, respectively, at feed rates of up to 60,000mm per minute. Rotary table axes offer rotational motion of 240 degrees (plus or minus120 degrees) on the A-axis and a full 360-degree (continuous rotation) on the C-axis.
 
It comes standard with a 15,000-rpm HSK-A63 spindle with 120Nm (42Nm continuous) of torque for high-speed machining of various workpiece materials including steel, aluminum and titanium. Optional spindle configurations include a 20,000-rpm HSK-A63 spindle and 30,000-rpm HSK-F63 spindle.
 
The unit features roller linear guides across all linear axes for rigidity and stiffness while maintaining productive feed rates. Y- and Z-axes are located above the worktable, with the X-axis located under the table to ensure a cantilever-free design and highest positioning accuracies.
 
The D300 uses the Makino Professional 5 Control, which provides a Windows CE GUI with touch-screen access, and the networking and storage capabilities of a data center. It also features Makino's Super Geometric Intelligence (SGI.4) software for high-feed-rate machining of complex, 3Dcontoured shapes involving continuous, tiny blocks of NC data.
 
The D300 incorporates control enhancements to improve 5-axis machining performance and operability. The tool center point (TCP) control allows programming based on the tool tip so that tool-compensation features can be applied. Further TCP developments also improve the cutter path to achieve greater surface quality.
