Overview

The Hyundai WIA L400MA is a heavy-duty 10-inch chuck CNC turning center built for large-diameter production turning of flanges, rings, large shafts, and complex housings in energy, aerospace, and heavy equipment manufacturing. With a 520mm swing over bed, maximum turning diameter of 460mm, turning length up to 1,500mm, and a 30 kW spindle delivering 3,500 RPM, the L400MA provides the combination of large work envelope and high cutting power needed for productive machining of large, difficult workpieces in a single setup.

Hyundai WIA engineered the L400MA around box-way construction on all axes, recognizing that the heavy interrupted cuts, large-diameter facing operations, and boring of thick-walled cylinders typical in energy and aerospace work demand maximum structural rigidity over high traverse speed. The 45-degree slant-bed design promotes efficient chip evacuation from the large chip volumes generated during heavy roughing of steel and stainless forgings and castings. The Fanuc 0i-TF Plus control is standard, providing familiar programming and broad support from the global Fanuc ecosystem.

A 12-station heavy-duty turret with VDI 50 toolholding accommodates the large boring bars, face grooving tools, and heavy turning holders needed for 10-inch-class heavy turning operations. Programmable servo tailstock with 160mm quill diameter provides support for long-shaft workpieces and coordinates with machining programs for automatic positioning. Optional live tooling with ±52.5mm Y-axis adds milling, drilling, and tapping capability for parts requiring cross-holes, radial features, and off-center milled geometry without a secondary machine setup.

The L400MA competes with the Okuma LB4000 EX II, Mazak Quick Turn Nexus 450, and Doosan Puma 600 in the large turning center segment. For manufacturers seeking heavy-duty 10-inch-class turning capability with Fanuc control familiarity at a competitive price, the L400MA offers a proven platform. New machine pricing typically ranges from $250,000 to $400,000. Specs sourced from Hyundai WIA published data.

Strengths & Limitations

Strengths

10-inch chuck with 30 kW spindle power handles heavy roughing of large-diameter steel, stainless, and alloy workpieces common in energy and aerospace production
Box-way construction on all axes provides the rigidity and vibration damping required for deep cuts on large-diameter forgings, castings, and rings
Fanuc 0i-TF Plus control offers wide ecosystem support, simple post processor setup, and familiar operator interface for shops already running Fanuc machines
Competitive pricing of $250,000 to $400,000 delivers large-chuck heavy-turning capability at a lower cost than equivalent Japanese-brand platforms

Limitations

3,500 RPM maximum spindle speed is appropriate for large-diameter work but limits utility for small-diameter high-speed turning operations on the same machine
Lower rapid traverse rates (18 m/min Z) reflect the box-way construction designed for rigidity — less significant in long-cycle heavy turning applications
Optional Y-axis and live tooling add cost; shops needing mill-turn capability should budget accordingly or consider the L400MC variant

Best For

Oil and gas manufacturers producing large flanges, wellhead components, valve bodies, and pipe fittings from tough alloy steels and stainless Power generation and heavy equipment shops turning large rings, housings, hubs, and shafts up to 460mm diameter and 1,500mm length Aerospace suppliers producing large structural rings, frames, and bearing housings in aluminum, titanium, and Inconel alloys Job shops running large, high-value turned parts where box-way rigidity reduces vibration risk and Fanuc control simplifies programming

Frequently Asked Questions

01 How does the L400MA compare to the L300MC?

The L400MA is the heavy-duty large-chuck version with a 10-inch chuck, 520mm swing, and 30 kW spindle, designed for large-diameter heavy-cut turning. The L300MC is the 8-inch chuck mid-size machine with standard Y-axis milling as an integrated feature, targeting parts requiring turning plus milled features. The L400MA focuses on maximum turning capability; the L300MC focuses on mill-turn versatility in a smaller workpiece range.

02 Is Y-axis milling available on the L400MA?

Yes, Y-axis live tooling with ±52.5mm travel is available as an option on the L400MA. The live tooling drive operates up to 6,000 RPM and uses VDI 50 driven tool holders compatible with a wide range of tooling suppliers. Shops regularly requiring milled features on large turned parts should specify Y-axis at the time of order.

03 What materials can the L400MA machine effectively?

The L400MA is well-suited to steel, stainless steel, alloy steel, ductile iron, aluminum, and nickel-based superalloys. The 30 kW spindle provides adequate torque for deep cuts in tough stainless and Inconel at appropriate speeds and feeds. Shops turning large titanium aerospace components should verify that the spindle speed range matches the surface speed requirements for titanium at the workpiece diameter being turned.

04 What tailstock options are available?

The L400MA includes a servo-driven programmable tailstock with a 160mm quill diameter, providing support for long shaft workpieces and coordinating automatic quill positioning with machining programs. The tailstock can be programmed to advance to a specified position, apply a defined thrust force, and retract on command — enabling fully automatic support cycles without manual tailstock adjustment between workpieces.

05 What is the typical lead time for an L400MA?

Standard Hyundai WIA L400MA configurations typically ship within 14 to 22 weeks from order confirmation. Machines with Y-axis live tooling, sub-spindle, or extended bed options may have longer lead times. Hyundai WIA's North American distributor network handles order coordination, application support, and installation for most regions.
