Overview
The Hyundai WIA L300MC/LMC/MSC is the mill-turn variant family of the L300 platform with a 12-inch chuck, combining large-bore turning capacity with live milling capability for complex part processing. The L300MC is the standard-length mill-turn, the L300LMC extends to a long bed for shaft work, and the L300MSC adds a sub-spindle for complete done-in-one machining.
All three models share a belt-driven spindle at 3,000 RPM producing 787/465 Nm of torque with 22/18.5 kW (30/25 hp) power — sufficient for productive roughing on the medium-to-large diameter parts that a 12-inch chuck accommodates. The 4,000 RPM live milling turret enables cross-drilling, flat milling, hexagonal features, and tapping without transferring parts to a VMC. The L300MSC's 8-inch sub-spindle handles back-working operations including rear facing, boring, and cross-features.
Maximum turning diameters are 500 mm across all variants, with turning lengths of 600 mm (L300MC/MSC) and 1,260 mm (L300LMC). Box-way guideways provide the rigidity needed for combined turning and milling operations on large workpieces, while X-axis travel of 355 mm accommodates the larger tool offset requirements of 12-inch chuck work. The 12-station turret handles both standard turning tools and live milling heads in 25/50 mm tooling sizes.
Priced from approximately $110,000 for the L300MC to $170,000+ for the L300MSC, these machines compete with the DN Solutions Puma GT-3100M, Mazak QT-350MY, and Okuma LB3000 EX II M in the 12-inch chuck mill-turn category. The Fanuc 0i-TF Plus control with full C-axis support is standard. For shops running complex 12-inch chuck parts that currently require secondary VMC operations, the L300MC family delivers significant cycle time and handling cost reductions.

Strengths & Limitations
Strengths
- 12-inch chuck with live tooling enables complex mill-turn operations on medium-to-large diameter parts
- 4,000 RPM live milling eliminates secondary VMC operations for cross-drilling, flats, and hex features
- L300MSC sub-spindle provides complete done-in-one machining including back-working on both part ends
- Box-way construction delivers rigidity and vibration damping for combined turning and milling cuts
- L300LMC long-bed variant handles shaft-type mill-turn work up to 1,260 mm turning length
- 355 mm X-axis travel accommodates large tool offsets for 12-inch chuck work
Limitations
- 3,000 RPM spindle speed limits surface speed on small-diameter finishing operations
- Belt-driven spindle produces less torque (787 Nm) than the gear-driven L300C's 1,131 Nm
- L300MC/MSC standard-bed models limited to 600 mm turning length — long parts require the LMC variant
- Higher price point than 2-axis L300C variants — justify with secondary operation elimination

Frequently Asked Questions
01
The L300MC adds live milling capability with C-axis and a 4,000 RPM milling spindle, while the L300C is a 2-axis turning-only machine. The L300MC uses a belt-driven spindle (787 Nm torque) versus the L300C's gear-driven spindle (1,131 Nm). Both share the 12-inch chuck and box-way construction. Choose the MC when parts require milling features; choose the C when maximum turning torque is the priority.
02
The L300MC standard-bed mill-turn typically sells for $110,000-$135,000. The L300LMC long-bed variant runs $130,000-$155,000. The L300MSC with sub-spindle reaches $150,000-$170,000+. Pricing varies by dealer region and option packages.
03
The 4,000 RPM live milling turret handles cross-drilling, flat milling, hexagonal features, keyways, tapping, and angular features. Combined with the C-axis for spindle indexing and interpolation, the L300MC can produce complex parts that would otherwise require a secondary VMC setup.
04
The 8-inch sub-spindle automatically picks up the part from the main spindle after front-side operations are complete. The sub-spindle then positions the part for back-working operations including rear facing, boring, drilling, and tapping. This eliminates manual part handling and ensures concentricity between front and rear features.
