Makino DA300

The Makino DA300 is a compact simultaneous 5-axis vertical machining center built for throughput rather than envelope. Travels are 450 mm (17.7 in) in X, 620 mm in Y and 500 mm (19.7 in) in Z, over a 300 × 340 mm (11.81 × 13.38 in) trunnion table. The A-axis covers 150°, from +30 to -120, and the C-axis rotates a full 360°.

Workpiece capacity is quoted three ways, and the differences are the most useful thing on the spec sheet. Standalone, the machine takes ø17.7 in × 15.7 in at 551 lb. With a manual chuck fitted, capacity drops to ø17.7 in × 11.6 in at 474 lb. With the WPS automation system it falls again to 14.0 in square × 11.6 in at 177 lb, against a maximum payload of 250 kg (551 lb). That final tier is the one to plan against if automation is the reason for buying the machine: adding pallet handling costs most of the standalone payload, and a fixture designed for the standalone figure will not run automated. Conditional maximum workpiece is 450 mm diameter × 400 mm.

The spindle is 20,000 rpm on HSK-A63. That taper and speed combination is aimed at small-diameter tooling at high surface speed — the DA300 is set up to run modest cutters fast rather than large cutters hard.

Motion specifications carry the same intent. Rapid traverse and maximum cutting feed are both 60,000 mm/min (2,362 ipm). A cutting feedrate matching rapid traverse is unusual and it means the machine can be programmed at high feed through the whole toolpath rather than only in air, which is where high-feed milling strategies actually recover cycle time. Chip-to-chip is 3.5 sec.

Tool capacity is 60 as standard, with 118 and 311 available. Sixty pockets on a machine this size is generous and is what makes long unattended running realistic — enough for a complete job plus duplicates. Tools reach Ø70 mm with a full magazine, Ø140 mm (5.51 in) with adjacent pockets empty, at 8 kg (17.6 lb).

The DA300 suits medical, aerospace and precision contract shops running small complex parts in volume.
