Ecoca MT-412MC

The Ecoca MT-412MC exists because long shafts often need more than turning. Keyways, wrench flats, cross-drilled oil holes and drive slots are common on exactly the kind of part that fills a 2 or 3 metre bed, and moving such a part to a mill for them is slow and awkward. This model is the MT-412 with a milling function, built to finish those features in the lathe.

Its milling spindle is listed at 3,200 rpm, the same figure as the main spindle. Compared with the 5,000 rpm of the MT-310MC that is slow, and it tells you what the driven tools are for: larger drills, taps and end mills in steel, not small cutters at high speed. Ecoca prints no milling power or torque, so confirm the drive rating against the biggest tool you intend to run.

Capacity is close to the two-axis model. Turning length is offered in the same five steps, 730 / 1,000 / 1,500 / 2,000 / 2,980 mm (28.7 / 39.4 / 59.1 / 78.7 / 117.3 in). Turning diameter is 440 mm (17.3 in), where the MT-412 allows 510 mm (20.1 in). The chuck is 12 in (305 mm), the motor 18.5/22 kW (24.8/29.5 hp), and the turret has 12 stations in either servo or hydraulic form.

Two gaps in the published data should be closed before ordering. The weight row of the series table contains a misprint, so the machine weight has to come from Ecoca directly. And the table shows no Y axis, which means milled features sit on the centreline unless Ecoca confirms otherwise. Living tool holders and sleeves are optional.
