Makino will be demonstrating its latest full five axis machine solution, the DA300 vertical machining centre, at this year’s IMTS in booth #S-338700.

The DA300 combines speed, precision and flexibility for complex part applications. It delivers productive capabilities for multi-axis workpieces in a small machine footprint.
The DA300 is designed for single setup, multi-side accessibility, or full-contouring capability to handle a wide variety of complex production part applications commonly found in industrial hydraulic and pneumatics elements, optical, electrical and semiconductor components, medical and dental products, die-cast parts, automotive components and aerospace parts.
“The DA300 integrates numerous features that increase productivity and efficiency by providing significant reductions in non cut time,” said Bill Howard, VMC product manager at Makino. “The machine provides a 50 per cent reduction in spindle acceleration time, 15 per cent reduction in positioning time, 40 per cent reduction in tool-change chip-to-chip time and includes a standard vision-type broken tool sensor [Vision B.T.S.] that optically checks tools outside the work zone to ensure tool consistency and part quality while simultaneously reducing non cut time during tool changes by 80 per cent. Individually, each element reduces part cycle time and increases productivity; however, when all of these time savings are combined, the result is a dramatic advantage in reduced part-production times and increased profitability.”
The DA300 worktable is an integral, 340mm by 300mm table, accommodating workpiece sizes up to 450mm in diameter, 400mm tall and weighing 250 kg. The machine provides X-, Y- and Z-axis travels of 450mm, 620mm and 500mm, respectively, at feed rates of up to 60,000mm per minute. The direct-drive, motor-driven A-axis table offers 150 degrees (+30 to -120) of tilt capability at 100 rpm. The rotary C-axis has full 360-degree rotational positioning at 150 rpm. Combined, these rotational axes have the range and speed necessary to achieve the highest productivity in complex five face or full five axis machining application. Equipped with scale feedback on all axes, the DA300 also offers a rare blend of speed and precision.
