MAKINO’s latest full five-axis machine solution is the DA300 vertical machining center, combining speed, precision and flexibility for complex part applications. Drawing on design characteristics from both vertical and horizontal machine platforms, the DA300 “delivers the highest productive capabilities for multi-axis workpieces in the smallest of machine footprints.” It is described as a single setup, multi-side accessible, or full-contouring operation for processing complex parts comming in industrial hydraulic and pneumatics elements, optical, electrical and semiconductor components, medical and dental products, diecastings, automotive components, and aerospace parts.
“The DA300 integrates numerous features that increase productivity and efficiency by providing significant reductions in non-cut time,” stated Bill Howard, VMC product manager. “The machine provides a 50% reduction in spindle acceleration time, 15% reduction in positioning time, 40% reduction in tool-change chip-to-chip time, and (it) 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%.
“Individually, each element reduces part cycle time and increases productivity,” Howard emphasized, “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, 340X300-mm table, accommodating workpiece sizes up to 450 mm in diameter, 400 mm tall and weighing 250 kg. The machine provides X-, Y- and Z-axis travels of 450, 620, and 500 mm, respectively, at feed rates of up to 60,000 mm 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 for high productivity in complex five-face or full five-axis machining.
