Hyundai WIA L300LMA

The Hyundai WIA L300LMA is the long member of the L300 line with live tools: 1280 mm (50.4 in) of turning length and 1,350 mm (53.1 in) of Z travel behind a 10 in (254 mm) chuck, with driven tools running to 4,000 rpm.

Length is the reason to pick it. The L300A, on the same 290 mm (11.4 in) of X travel, stops at 720 mm (28.3 in) of turning length, so the L300LMA handles shafts about 78% longer. The cost is diameter: maximum turning diameter is 410 mm (16.1 in) here against 500 mm (19.7 in) on the L300A. A part near full length in a 10 in chuck is slender, and the headline table gives no tailstock or steady-rest figures, so settle the work support with WIA before ordering.

The spindle is belt driven and tops out at 3,500 rpm. Power is printed as 22 / 18.5 kW (29.5 / 24.8 hp) and torque as 493.4 / 414.9 N·m (363.9 / 306 ft-lbf). The gear-driven L300A lists 739 / 622 N·m (545.1 / 458.8 ft-lbf) from the same motor figures, so this machine has less low-speed torque to rough with. For shaft work at moderate diameters that is rarely the limit; for a heavy cut near 410 mm it can be.

Milling and drilling come from the 12-station turret. No Y travel is listed, so off-centre flats and pockets are not something to count on from this table. Rapids are 20 m/min (787 ipm) on X and 24 m/min (945 ipm) on Z, which matters more here than on a short machine because the turret has a long bed to cross between the chuck and the far end of the part.
