Hyundai WIA LV2000MM

The Hyundai WIA LV2000MM is a vertical turning center for parts up to 2,000 mm (78.7 in) in diameter and 1,700 mm (66.9 in) in height, with an 18-station turret and live tooling that runs to 2,400 rpm. The gear-driven table tops out at 258 rpm and delivers 22,096 / 17,916 N·m (16,298 / 13,214.8 ft-lbf) from 37 / 30 kW (49.6 / 40.2 hp).

Live tooling changes what a lathe of this size is used for. Parts two metres across are slow and risky to move between machines, and each move means a crane lift and a fresh set-up to dial in. With driven tools on the turret, bolt circles, tapped holes and milled faces can be put in while the part is still clamped from turning, so those features stay concentric with the turned diameters. Eighteen stations leave room for the drills and mills beside the turning tools.

The spindle is geared for torque. The LV1400 has the same 37 / 30 kW rating but is listed at 8,035 / 6,515 N·m (5,926.6 / 4,805.5 ft-lbf) and 492 rpm, so the LV2000MM gives up roughly half the speed for about 2.75 times the torque. That suits a 2,000 mm rim, where surface speed is high even at low rpm. Near the centre of the table, 258 rpm is slow, and facing down to a small bore will take time.

Two points need a conversation with Hyundai WIA before ordering. Z travel is 915 mm (36 in) against a 1,700 mm turning height, so ask how the full height is reached. The table also gives no X travel or table load. Rapids are 12 / 12 m/min (472 / 472 ipm) on X/Z.
