Emco Universalturn 90

Two bed lengths and an optional counter spindle are what the Emco Universalturn 90 adds to the shaft-lathe layout of the Maxxturn 95. Distance between centres is 1430 | 2230 mm and Z travel 1360 | 2160 mm, with bar listed as up to 102 mm and a maximum turning diameter of 500 mm (19.7 in).

The spindle is the familiar pairing on an A2-8 nose: 3500 / 2500 rpm, 33/42 kW and 800/1040 Nm, where the second figure of each pair is the slower, stronger drive. Emco lists a counter spindle with a KK6 interface, one size below the KK8 main spindle. The product table gives no speed or power for it, so those figures have to come with the quotation.

Where this machine clearly moves on is the driven tooling. With the BMT55P turret the drive is rated up to the second values in 4000 / 12000 rpm, 8 / 23.5 kW and 45 / 56 Nm. A milling drive of that power on a lathe turret changes what can be done in one setup: larger end mills, deeper drilling, and less need to pass shafts on to a machining centre. The VDI 40 turret remains for shops with existing holders.

Y travel is -60/+80 mm and X travel 360 mm (14.2 in). An NC-controlled steady rest or tailstock is optional; the tailstock row gives 1,050 mm (41.3 in) of travel with an MK4 taper. The two beds measure 6312 x 2249 x 2162 | 7378 x 2476 x 2355 mm and weigh 11000 | 13000 kg.
