Ecoca MT-412

Five bed lengths, from 730 mm (28.7 in) to 2,980 mm (117.3 in) of turning length, make the Ecoca MT-412 the first long-bed machine in the MT range. Ecoca sums it up as a 690mm swing with 3-meter turning length and calls it an economic choice for big turning parts. The chuck is 12 in (305 mm), the spindle runs to 3,200 rpm and the motor is listed as 18.5/22 kW (24.8/29.5 hp).

The full list of turning lengths is 730 / 1,000 / 1,500 / 2,000 / 2,980 mm (28.7 / 39.4 / 59.1 / 78.7 / 117.3 in). The step from the MT-312 is large. That model ends at 980 mm (38.6 in), while this one starts near there and carries on to roughly three times the length. Maximum turning diameter is 510 mm (20.1 in), with 690 mm (27.2 in) of swing over the bed and 480 mm (18.9 in) over the cross slide.

Long beds bring long, slender workpieces, and those need support. A hydraulic tailstock and live center are on the standard accessories list. The page for this model does not mention a steady rest, so if the shafts are thin for their length, raise the question with Ecoca; the larger MT-415 PLUS page does list one as optional.

One caution on the data. The weight cell in Ecoca's table for this series contains a figure that is plainly a misprint, so the row cannot be relied on. Get the weight and footprint for the chosen bed length in writing. The turret has 12 stations and can be a servo or hydraulic type, and the guideways are HARD RAIL on a 30 degree slant bed.
