Hyundai WIA LV1400

The Hyundai WIA LV1400 is a gear-driven vertical turning center for parts up to 1,400 mm (55.1 in) in diameter and 850 mm (33.5 in) in height. Its spindle is listed at 8,035 / 6,515 N·m (5,926.6 / 4,805.5 ft-lbf) of torque, 37 / 30 kW (49.6 / 40.2 hp) and a top speed of 492 rpm.

Those three numbers belong together. A gear drive turns moderate motor power into very high torque by giving up speed, which is the right exchange for a table this size: at 1,400 mm even a low table speed produces a high surface speed at the rim, and the cut needs torque to keep going. The other side of it is that 492 rpm leaves bores and faces near the centre well short of the surface speed carbide prefers, so those features take longer than the rim does.

Tooling is a 12-station turret. Rapids are 12 / 12 m/min (472 / 472 ipm) on X/Z, half the 24/24 m/min (945 ipm) of the smaller LV1100 Series, so this is not a machine that makes its cycle time on positioning. Z travel is 800 mm (31.5 in), a little less than the 850 mm turning height. The table lists no X travel and no table load, both of which should be confirmed against the part and its fixture.

Within the range the LV1400 is the middle step. The LV1100 Series turns 1,160 mm (45.7 in) and has more power at 65/45 kW (87/60 hp). The LV2000MM shares the 37 / 30 kW rating but is geared lower still, with 22,096 / 17,916 N·m (16,298 / 13,214.8 ft-lbf) at 258 rpm, and it has 18 tools with live tooling at 2,400 rpm where the LV1400 lists none.
