Hyundai WIA L400A

The Hyundai WIA L400A is a large-bore CNC turning center built for shops that regularly machine large-diameter components including flanges, rings, valve bodies, and large rotational parts for energy, oil and gas, and heavy equipment sectors. With a 15-inch chuck, 610 mm (24 in) maximum turning diameter, and up to 1,500 mm (59 in) maximum turning length depending on bed configuration, the L400A represents Hyundai WIA's capability in the heavy-duty turning segment.

The spindle produces 3,500 RPM maximum with 30/22 kW (40/30 hp), delivering the torque necessary for large-diameter face turning and heavy boring operations that define this machine class. Bar capacity of 105 mm (4.1 in) covers the larger-diameter bar stock common in energy and heavy equipment applications. The Fanuc i-Series control is standard, and the 12-station BMT turret provides tooling capacity for complex programs including roughing, finishing, and grooving in a single setup.

The L400A's slant-bed casting is significantly heavier than smaller L-series machines, providing the mass and rigidity required for productive deep cuts in large forgings and castings. The machine competes with the DN Solutions Puma 600, Okuma LB4000 EX, and Mazak QT-450, all of which serve similar heavy-duty turning applications. Hyundai WIA's ability to offer competitive specifications at lower price points makes the L400A particularly attractive for shops with budget constraints who still need large-bore capability.

At $100,000-$145,000 new, the L400A costs meaningfully less than equivalent machines from Okuma or Mazak while delivering comparable capability for most large turning applications. Shops in the energy sector, heavy equipment manufacturing, and general job shops that regularly see large diameter work will find the L400A well-suited to their requirements.
