EMAG VL 8

The EMAG VL 8 is the largest machine in the VL vertical turning range listed here, with 1,110 mm (43.5 in) of X travel and a 500 mm (19.5 in) chuck for parts up to 400 mm (15.5 in) in diameter and 300 mm (12 in) long. The spindle delivers 47.5 / 34.5 kW (64 / 46.5 hp) and 780 / 600 Nm (575.5 / 442.5 ft-lb), with a top speed of 2,850 rpm.

Torque is what this machine is bought for. 780 Nm on a 400 mm part allows deep roughing passes on heavy blanks where a smaller spindle would stall or chatter. The other side of that is speed: 2,850 rpm is the lowest top speed in the range, so bores and small diameters on the same part are cut at reduced surface speed.

Z travel is 595 mm (23.5 in) and swing is 520 mm (20.5 in). Both axes rapid at 30 m/min (1,181 ipm), so the long X stroke does not cost much time on each move. The 12-station turret uses VDI 60 holders, the heaviest of the VL sizes, which is right for the cutting forces but means a separate holder stock from smaller machines.

The VL 6 below it takes parts up to 300 mm (12 in) with 460 / 340 Nm (339.5 / 251 ft-lb) and runs to 3,100 rpm. A buyer weighing the VL 8 against the VM 9 should note that the VM 9 also takes 400 mm (15.5 in) parts but lists 83 kW (111 hp) and 990 Nm (730 ft-lb). The VL 8 table does not list driven tools, a Y axis, the control or machine weight.
