Makino announces the D300 5-axis vertical machining center as the newest entry into the 5-axis machining arena. Similar to the D500, this 5-axis machining center is designed specifically for small, complex, 3-D contouring of high-quality part production as typically seen in aerospace machining, medical manufacturing, high-end job shop and die/mold applications.
"From roughing to finishing, the D300 enables manufacturers to reduce setups, slash cycle times and improve accuracy in the toughest machining processes," said William Howard, Makino Vertical Product Line Manager. "The rigidity and thermal stability of its direct-drive rotary table ensures sustained dynamic accuracy, while its speed provides rapid positioning and feedrates to reduce overall lead-times."
The D300 worktable offers a work area diameter of 300 mm, accommodating workpiece sizes up to 450 mm by 270 mm and 120 kg. The machine provides X-, Y- and Z-axis travels of 300 mm, 500 mm and 350 mm, respectively, at feed rates of up to 60,000 mm per minute. Rotary table axes offer rotational motion of 240 degrees (+/- 120 degrees) on the A-axis and a full 360-degree (continuous rotation) on the C-axis.
The machine comes standardly equipped with a 15,000 RPM HSK-A63 spindle with 120 Nm (42 Nm continuous) of torque for flexible, 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.
"Makino uses direct-drive motor technology in the D300's C-axis rotary table and A-axis trunnion for outstanding positioning accuracy and repeatability. The ultra-high-torque direct-drive motors also provide superior acceleration and rotary speed characteristics that can reduce cycle times of complex 5-axis simultaneous machining applications by up to 60 percent," said a company spokesperson.
According to Makino, the D300 axis configuration is unique, delivering added precision performance. The length of the trunnion assembly runs parallel to the X-axis motion only, making the trunnion assembly deflection-free during quick axis motion for greater accuracy than traditional 5-axis configurations.
The machine features roller linear guides across all linear axes for rigidity and stiffness while maintaining productive rapid and feedrates. Y- and Z-axes are located above the worktable, with the X-axis located under the table to ensure a cantilever-free design and positioning accuracies.
The D300 uses the Makino Professional 5 Control, which provides a Windows CE graphical user interface (GUI) with touch-screen access, and the networking and storage capabilities of a data center. This data center features a flexible, user-friendly program and data management for quick changes from one set-up to the next. Its built-in Ethernet networking capability offers ready integration to off-machine program storage.
Also featured in the D300 is Makino's proprietary, next-generation Super Geometric Intelligence (SGI.4) software developed specifically for high-feedrate, tight-tolerance machining of complex, 3-D contoured shapes involving continuous tiny blocks of NC data designed for high production rates. "SGI.4 helps deliver the lowest cycle times and costs achievable by reducing machining cycle times on dies, complex cavities, and cores and medical parts by as much as 40 percent when compared to most other control technologies," said the spokesperson.
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. "Dedicated user-friendly screens simplify the overall application of 5-axis machining, and easy-to-apply functions prevent interference between the spindle and trunnion during automatic operation to improve risk-free production," said the spokesperson.
The machine can be upgraded for automation at any time with an automatic pallet changer.
