Overview
The Hyundai WIA L700LA/LMA is the largest turning center in the Hyundai WIA L-Series lineup, designed for the heaviest class of shaft, roll, and tubular turning work in industries including oil and gas, power generation, mining, and heavy equipment manufacturing. With a 24-inch chuck, 920 mm (36.2 in) maximum turning diameter, and 3,250 mm (127.9 in) maximum turning length, it handles workpieces that require the most substantial chucking and turning capacity available.
The gear-driven spindle operates at 1,500 RPM with 45/37 kW (60/50 hp) power, producing an exceptional 6,978/5,700 Nm of torque. The L700's torque output exceeds the L600 series (5,610 Nm) by 24%, driven by the lower spindle speed and gear ratios optimized for the 24-inch chuck's larger moment arm. This torque is essential when roughing heavy forgings, large-diameter rolls, and thick-wall pipe where tool engagement forces are extreme.
The L700LA is the 2-axis turning variant, while the L700LMA adds 3,000 RPM live milling for cross-drilling, keyways, and prismatic features without secondary setups. Both models feature all-axis box-way guideways, 500/3,280 mm X/Z axis travel, and a 12-station turret with 32/80 mm heavy-duty tooling. Rapid traverse is 12/12 m/min on both axes, consistent with the machine's heavy-duty positioning requirements.
Priced at approximately $300,000-$400,000, the L700LA/LMA represents the upper tier of Hyundai WIA's turning center portfolio. It competes with the Mazak Slant Turn 800, Okuma LB55 II, and European heavy-duty lathes from Heyligenstaedt and Tacchi. For shops requiring a 24-inch chuck capacity with Korean value pricing, the L700 platform delivers heavy-duty performance at a significant discount to European alternatives.

Strengths & Limitations
Strengths
- 24-inch chuck accommodates the largest class of forgings, castings, and tubular workpieces
- 6,978 Nm spindle torque is among the highest in the class for aggressive roughing on heavy components
- Gear-driven spindle ensures full torque delivery at any speed within the 1,500 RPM range
- 3,250 mm turning length handles long shafts, rolls, and pipe sections in a single setup
- L700LMA live milling eliminates secondary operations on large shaft components
- Korean manufacturing delivers significant cost advantage versus European heavy-duty lathes
Limitations
- 1,500 RPM maximum spindle speed limits the machine to large-diameter work — not suitable for small parts
- 12/12 m/min rapid traverse increases non-cutting time on complex multi-tool programs
- Major floor space and foundation investment required for a machine of this size class
- High capital cost ($300K-$400K) demands clear production volume to justify the investment

Frequently Asked Questions
01
The L700LA steps up to a 24-inch chuck (versus 18-inch), 1,500 RPM (versus 1,800 RPM), and 6,978 Nm torque (versus 5,610 Nm). Both share 920 mm maximum turning diameter, 3,250 mm turning length, and 45/37 kW spindle power. The L700's lower speed and higher torque reflect the optimization for larger-diameter chucked work where the 24-inch chuck's moment arm demands more torque.
02
The L700LA base model typically prices at $300,000-$350,000. The L700LMA with live milling runs $350,000-$400,000. These are major capital investments that compete favorably against European alternatives from DMG MORI, WFL, and Heyligenstaedt, which can exceed $500,000 for comparable capacity.
03
The L700 serves industries requiring large-diameter, long-length turning: oil and gas (drill collars, casing, risers), power generation (turbine shafts, rotors), mining (crusher shafts, rolls), marine (propeller shafts), and heavy manufacturing (press rolls, large bearings). Any application requiring a 24-inch chuck and 3+ meter turning length is a natural fit.
04
The 24-inch hydraulic chuck is standard with various jaw configurations for different workpiece geometries. Steady rests are essential for long shaft work and are available from Hyundai WIA and aftermarket suppliers. Follow rests, custom soft jaws, and specialized collet systems are available for specific applications.
