Overview
The Hyundai WIA L5100L Series is a large-bore, long-bed heavy-duty turning center family designed for the most demanding large-diameter shaft and tubular work. Available in four configurations — L5100L (21" chuck), L5100LM (21" chuck, live tooling), L5100LC (24" chuck), and L5100LMC (24" chuck, live tooling) — the series handles workpiece diameters up to 760 mm (29.9 in) with turning lengths exceeding 2,200 mm.
All variants feature gear-driven spindles with 45/37 kW (60/50 hp) power. The 21-inch chuck L5100L/LM models run at 1,500 RPM producing 4,112/3,382 Nm (L5100L) and 2,990/2,459 Nm (L5100LM) of torque. The 24-inch chuck L5100LC/LMC models operate at 1,000 RPM with 4,486/3,689 Nm torque — among the highest torque figures in the Hyundai WIA lineup, essential for heavy roughing on large-diameter forgings and castings.
Maximum turning diameters are 760 mm (L5100L/LC) or 690 mm (L5100LM/LMC), with turning lengths from 2,120 mm (LM/LMC) to 2,205 mm (L/LC). X/Z axis travel of 400/2,255 mm (L/LC) or 400/2,170 mm (LM/LMC) provides the generous work envelope needed for large components. The 12-station turret accepts 32/60 mm heavy-duty tooling, and the LM/LMC variants add 4,000 RPM live milling. Rapid traverse of 20/18 m/min reflects heavy-duty positioning.
Priced at approximately $280,000-$400,000, the L5100L Series sits between the L4000L and L600/L700 platforms, offering more swing than the L4000L while maintaining a more compact footprint than the 3.2-meter-bed L600/L700 machines. It competes with the Mazak QT-500, Okuma LB55 II, and DN Solutions Puma 5100 in the large-bore segment. The Fanuc 0i-TF Plus control is standard.

Strengths & Limitations
Strengths
- 760 mm maximum turning diameter handles large forgings, castings, and tubular components
- 4,486 Nm torque on the L5100LC enables aggressive roughing on the heaviest workpieces
- 45/37 kW gear-driven spindle delivers full torque across the entire speed range
- 2,205 mm turning length accommodates long shaft and cylinder work in a single setup
- Dual chuck sizes (21" and 24") allow right-sizing to specific workpiece requirements
- Box-way construction on all axes ensures maximum rigidity for heavy-duty cutting
Limitations
- 1,000-1,500 RPM spindle speed is strictly for large-diameter work — not suitable for small parts
- Major floor space and foundation investment required for a machine of this capacity
- High capital cost ($280K-$400K) requires clear production volume justification
- 18 m/min Z-axis rapid traverse increases non-cutting time on complex programs

Frequently Asked Questions
01
The L5100L offers significantly more swing: 760 mm turning diameter versus 570 mm, with 21"/24" chuck options versus 15"/21". Spindle power increases to 45 kW from 35-37 kW, and torque reaches 4,112-4,486 Nm versus 2,450-3,378 Nm. The L5100L also has more X-axis travel (400 mm versus 330 mm). Choose the L5100L when workpiece diameters exceed the L4000L's 570 mm capacity.
02
The L5100L with 21-inch chuck starts around $280,000-$320,000. The L5100LM with live tooling runs $310,000-$350,000. The L5100LC with 24-inch chuck prices at $320,000-$370,000. The L5100LMC with 24-inch chuck and live tooling reaches $360,000-$400,000.
03
The L5100LC runs at 1,000 RPM versus the L5100L's 1,500 RPM, with gear ratios optimized for the larger 24-inch chuck. Lower speed with the same 45 kW motor produces higher torque (4,486 Nm versus 4,112 Nm). The 24-inch chuck's larger moment arm demands this additional torque to maintain cutting performance at the workpiece periphery.
04
Standard hydraulic chucks in 21" or 24" configurations with various jaw designs. Steady rests and follow rests are essential for long shaft work and available from Hyundai WIA and aftermarket suppliers. Custom soft jaws, collet systems, and specialty fixtures can be sourced for specific applications.
