Overview
The Hyundai WIA L300C/LC is the large-bore variant of the L300 turning center platform, stepping up to a 12-inch chuck and 560 mm (22 in) maximum turning diameter for shops that need to swing bigger workpieces than the standard 10-inch L300A can accommodate. The L300C is the standard-length model with 720 mm maximum turning length, while the L300LC extends to 1,320 mm for long shaft and cylinder work.
Both models feature gear-driven spindles at 3,000 RPM producing 1,131/957 Nm of torque — substantially more than the 10-inch chuck L300A's 739 Nm. This torque advantage is critical when roughing large-diameter cast iron housings, steel flanges, and other heavy workpieces where the 12-inch chuck's larger swing generates higher cutting forces. The 26/22 kW (35/30 hp) spindle motor delivers the sustained power needed for productive material removal rates on big parts.
Box-way guideways on both axes provide the vibration damping essential for stable cutting at the larger workpiece diameters the 12-inch chuck enables. X-axis travel of 355 mm and Z-axis travel of 750 mm (L300C) or 1,350 mm (L300LC) cover the full work envelope. The 12-station turret accepts 25/50 mm tooling, and rapid traverse of 20/24 m/min keeps non-cutting time competitive.
The Fanuc 0i-TF Plus control is standard. Priced at approximately $80,000-$130,000, these large-bore variants compete with the Haas ST-25, DN Solutions Puma GT-3100, and Mazak QT-350 in the 12-inch chuck segment. For shops regularly machining parts that exceed 10-inch chuck capacity without needing the full investment of a 15-inch chuck machine, the L300C/LC provides an economical middle ground.

Strengths & Limitations
Strengths
- 12-inch chuck with 560 mm turning diameter handles larger flanges and housings than 10-inch chuck competitors
- Gear-driven spindle produces 1,131 Nm torque for aggressive roughing on large-diameter steel and cast iron
- Box-way construction provides superior vibration damping for stable heavy cuts on big workpieces
- L300LC long-bed variant extends turning length to 1,320 mm for shaft and cylinder applications
- 26/22 kW motor delivers sustained power for productive material removal on large parts
- Competitive pricing below comparable Japanese and European 12-inch chuck turning centers
Limitations
- 3,000 RPM maximum spindle speed limits surface speed on small-diameter finishing passes
- No live tooling option on the C/LC models — the L300MC/LMC variants add milling capability at higher cost
- Box ways require periodic maintenance and re-scraping over the machine's service life
- Larger 12-inch chuck increases workholding cost versus standard 10-inch setups

Frequently Asked Questions
01
The L300C steps up to a 12-inch chuck (versus 10-inch), 560 mm maximum turning diameter (versus 430 mm), and a more powerful 26/22 kW gear-driven spindle producing 1,131 Nm torque. It handles larger-diameter work at the expense of some spindle speed — 3,000 RPM versus 3,600 RPM. X-axis travel also increases to 355 mm.
02
The standard-length L300C typically sells for $80,000-$110,000 new. The long-bed L300LC runs $100,000-$130,000. Pricing varies by dealer and options. The 12-inch chuck variants carry a modest premium over the 10-inch L300A due to the larger spindle and frame.
03
The L300C/LC are 2-axis turning-only machines. For live tooling with a 12-inch chuck, look at the Hyundai WIA L300MC (standard bed) or L300LMC (long bed) variants, which add C-axis and live milling capability at 4,000 RPM. These are separate machine configurations, not field-upgrade options.
04
Both are 12-inch chuck 2-axis turning centers at comparable price points. The L300C features a gear-driven spindle and box-way construction for heavy-duty cutting. The Haas ST-25 offers a larger dealer network and the Haas NGC control. Torque, turning diameter, and turning length are similar. Choose based on local dealer support and control preference.
