Hyundai WIA SE2200Y Series

The Hyundai WIA SE2200Y Series puts a Y axis and live tooling on the 8 in (203 mm) chuck SE2200 platform. Y travel is 110 mm (4.3 in), live tools run to 6,000 rpm, and the main spindle is the belt-driven 4,500 rpm unit with 167 / 92 N·m (123.2 / 67.9 ft-lbf) of listed torque.

The Y axis is the reason to choose this series. With it a driven tool can cut away from the spindle centreline: flats, keyways with square walls, and cross holes that do not pass through the centre. Without it those features go to a mill as a second operation. Y rapid is 10 m/min (394 ipm), a third of the 30 m/min (1,181 ipm) on X and well short of the 36 m/min (1,417 ipm) on Z, which matters little because Y moves are short.

The turning envelope shrinks to make room. The SE2200 lists 350 mm (13.8 in) of maximum turning diameter and 307 mm (12.1 in) of turning length. This series lists 300 mm (11.8 in) and 288 mm (11.3 in) on the same 210 mm (8.3 in) X and 340 mm (13.4 in) Z travels. Spindle power is unchanged at 15 / 11 kW (20.1 / 14.8 hp).

The turret has 12 stations, and tool capacity is given as 12 tools with 24 optional. On a mill-turn part the stations fill quickly, because turning tools, drills and driven holders all share one turret, so the 24-tool option deserves a look when the machine is quoted. WIA's table has no sub-spindle row for this series, which means the back of the part needs a second chucking.
