Ecoca MT-415 PLUS

The Ecoca MT-415 PLUS is a heavy slant-bed lathe with a 15 in (381 mm) chuck, an 830 mm (32.7 in) swing over the bed and a 750 mm (29.5 in) maximum turning diameter. The name suggests a variant of the MT-415, but the table describes a different and much larger machine: the swing, the turning diameter, the motor and the longest bed are all bigger, and only the chuck size and the 2,500 rpm top speed carry over.

Power is the clearest change. The spindle motor is listed as 30/37 kW (40.2/49.6 hp). Guideways are given as Box way, and Ecoca adds that the Z axis runs on 3 guide ways with a large span. A third way under a long carriage spreads the cutting load and resists twisting when the turret works far from the bed centre, which matters at this diameter.

Five beds are listed, for turning lengths of 720 / 970 / 1,970 / 2,970 / 3,970 mm (28.3 / 38.2 / 77.6 / 116.9 / 156.3 in). Net weight climbs with them: 7,800 / 8,300 / 8,800 / 9,300 / 9,800 kg (17,196 / 18,298 / 19,400 / 20,503 / 21,605 lb). Ecoca describes the tailstock as sturdy and programmable and offers a steady rest as an option. On the two longest beds a steady rest is close to a necessity for anything slender.

A milling version appears in the same table as the MT-415plusMC. Its column is identical except for one row, a milling speed of 5,000 rpm. The turret has 12 stations, the bed is slanted at 30 degree, and holders for driven tools are optional.
