Emco Maxxturn 200

The Emco Maxxturn 200 turns parts up to 1,000 mm (39.4 in) in diameter and, on the longest bed, 2200 / 4200 / 6200 mm between centres. Emco gives a maximum workpiece weight of 6 t. This is heavy-duty turning for rolls, shafts and large hollow parts, with a main spindle rated 84 kW (112.6 hp) and 6,410 Nm (4728.0 lb-ft).

Spindle speed tops out at 1,800 rpm. On a part near the diameter limit that is still a high surface speed, and the torque is what counts. The optional counter spindle is listed with 53 kW (71.1 hp) and 4,400 Nm (3245.4 lb-ft) at 2000 / 2500 rpm, with a nose of A2-15'' / A2-11''. Machines without it use a tailstock whose quill is 200 mm (7.9 in) in diameter with 250 mm (9.8 in) of travel.

Emco builds the machine with one or two tool turrets. Each is a 12-station unit, listed as VDI 60 / BMT85, and all stations can be driven at up to 3,000 rpm with 19.8 kW (26.6 hp) and 116 Nm (85.6 lb-ft). That is milling-machine torque at the turret, enough for large face mills and deep drilling. The Y axis has +/-125 mm of travel and X travel is 550 mm (21.7 in).

Bed lengths follow the Z travel row, 2050-4050-6050 mm. Weight is given per bed length as BL 2200/4200/6200: 30/40/50 t. A Siemens control with dialog programming is fitted, and EMCONNECT runs on the Sinumerik ONE.
