Overview
The Hyundai WIA L4000 Series is a heavy-duty turning center family available in four configurations: L4000 (15" chuck, 2-axis), L4000M (15" chuck, live tooling), L4000C (21" chuck, 2-axis), and L4000MC (21" chuck, live tooling). All variants share 570 mm (22.4 in) maximum turning diameter and box-way construction, targeting shops that require substantial chucking capacity and high-torque spindles for large part production.
The 15-inch chuck L4000/L4000M models operate at 2,000 RPM with 35 kW (47 hp, gear) or 30 kW (40 hp, belt) power producing 2,450 Nm and 1,611 Nm torque respectively. The 21-inch chuck L4000C/L4000MC models run at 1,500 RPM with 37 kW (50 hp) gear-driven spindles producing an exceptional 3,378 Nm torque on the C variant. These torque figures position the L4000 Series well above mid-size turning centers for heavy roughing of forgings, castings, and large-diameter bar stock.
Maximum turning lengths range from 958-1,043 mm depending on variant, with X/Z axis travel of 330/1,105 mm providing a generous work envelope. The 10-station turret (L4000/C) or 12-station turret (L4000M/MC) accepts 32/60 mm heavy-duty tooling. The M and MC variants add 4,000 RPM live milling with C-axis for cross-drilling and feature milling without secondary operations. Rapid traverse of 16/20 m/min reflects the heavy-duty positioning requirements.
Priced at approximately $130,000-$200,000, the L4000 Series competes with the Mazak QT-350, Okuma LB4000, DN Solutions Puma 4100, and Haas ST-35 in the large-bore heavy-duty turning segment. The Fanuc 0i-TF Plus control is standard across all variants.

Strengths & Limitations
Strengths
- Up to 3,378 Nm spindle torque on the L4000C enables aggressive roughing on large forgings and castings
- Dual chuck-size options (15" and 21") allow right-sizing to specific workpiece diameter requirements
- Box-way construction on all variants provides rigidity and damping for heavy interrupted cuts
- 570 mm turning diameter with 1,043 mm turning length covers a broad range of large-part applications
- Live milling variants eliminate secondary VMC operations for complex large-diameter parts
- Competitive pricing versus Japanese and European alternatives in the large-bore segment
Limitations
- 1,500-2,000 RPM spindle speed limits surface speed on smaller-diameter finishing work
- 16/20 m/min rapid traverse is slower than compact turning centers, increasing non-cutting time
- 10-station turret on base models may limit complex programs requiring many tool changes
- Heavy machine weight requires substantial floor space and adequate foundation capacity

Frequently Asked Questions
01
The L4000 uses a 15-inch chuck at 2,000 RPM with 2,450 Nm torque. The L4000C steps up to a 21-inch chuck at 1,500 RPM with 3,378 Nm torque and a 37 kW motor. Both share the same 570 mm turning diameter, 330/1,105 mm axis travel, and box-way construction. Choose the C variant when workpieces require the larger 21-inch chuck capacity.
02
The base L4000 with 15-inch chuck starts around $130,000-$155,000. The L4000M with live tooling runs $150,000-$175,000. The L4000C with 21-inch chuck prices at $155,000-$180,000. The L4000MC with 21-inch chuck and live tooling reaches $175,000-$200,000. Pricing varies by dealer and options.
03
The L4000C's 37 kW motor and lower 1,500 RPM speed produce 3,378 Nm through gear ratios optimized for the 21-inch chuck. The larger chuck's moment arm requires more torque to maintain cutting performance at the workpiece periphery. The L4000's 15-inch chuck at 2,000 RPM produces 2,450 Nm, which is still exceptional for its class.
04
Both are Korean heavy-duty turning centers with comparable specifications, box-way construction, and Fanuc controls. The Puma 4100 has a more established global reputation and dealer network. The L4000 offers competitive pricing. Specifications are similar enough that dealer proximity and support quality should drive the decision.
