Overview
The Hyundai WIA HD3100A/MA is a mid-size heavy-duty turning center pair featuring a 10-inch chuck, box-way construction, and belt-driven spindles designed for shops that need solid rigidity and competitive rapid traverse in a production turning platform. The HD3100A is the base 2-axis model with a 10-station turret, while the HD3100MA adds live milling capability with a 12-station turret.
Both models share a belt-driven spindle at 3,500 RPM with 26/18.5 kW (35/25 hp) producing 734/522 Nm of torque — meaningfully more power than the HD2208/2600 series and competitive with the L300A in the 10-inch chuck segment. The HD3100A swings 500 mm (19.7 in) maximum turning diameter, while the HD3100MA accommodates 420 mm (16.5 in) with the live tooling hardware. Maximum turning length is 780 mm (HD3100A) or 740 mm (HD3100MA).
Box-way guideways on both axes provide the vibration damping advantage that distinguishes the HD line from linear-guide competitors. Rapid traverse of 24/30 m/min (X/Z) is a standout specification — the 30 m/min Z-axis speed is exceptionally fast for a box-way machine, keeping non-cutting time competitive with linear-guide alternatives. X/Z axis travel of 265/830 mm provides a generous work envelope.
The Fanuc 0i-TF Plus control is standard. Priced at approximately $70,000-$110,000, the HD3100A/MA competes with the Haas ST-20, DN Solutions Lynx 2600, and Mazak QT-250 in the mid-size heavy-duty turning category. The combination of box-way rigidity, 30 m/min Z rapids, and competitive pricing makes the HD3100A/MA a strong value proposition for production turning shops.

Strengths & Limitations
Strengths
- Box-way construction with 30 m/min Z-axis rapids combines rigidity with fast non-cutting positioning
- 26/18.5 kW spindle with 734 Nm torque provides strong cutting power for aggressive roughing in steel
- 500 mm maximum turning diameter on the HD3100A exceeds many competitors in the 10-inch chuck class
- 830 mm Z-axis travel provides generous turning length for shaft and long-part work
- HD3100MA adds live milling with a 12-station turret for done-in-one complex part processing
- Competitive pricing positions well against Haas ST-20 and DN Solutions Lynx 2600
Limitations
- 3,500 RPM spindle speed limits surface feet per minute on small-diameter finishing passes
- 265 mm X-axis travel is moderate for the turning diameter capacity
- 10-station turret on the base HD3100A limits complex multi-tool programs
- Hyundai WIA's North American dealer network is smaller than Haas and Mazak

Frequently Asked Questions
01
Both are 10-inch chuck box-way turning centers with similar pricing. The L300A uses a gear-driven spindle at 3,600 RPM with 739 Nm torque, while the HD3100A is belt-driven at 3,500 RPM with 734 Nm. The HD3100A has faster Z-axis rapids (30 m/min versus 24 m/min) and more Z-axis travel (830 mm versus 750 mm). The L300A has slightly more X-axis travel (290 mm versus 265 mm). Choose based on whether you prioritize gear-drive torque characteristics or faster rapid traverse.
02
The base HD3100A typically sells for $70,000-$85,000. The HD3100MA with live tooling runs $90,000-$110,000. Pricing is competitive with the Haas ST-20 and DN Solutions Lynx 2600 at similar or lower price points.
03
The HD3100A product page does not list a specific milling speed for the MA variant, but based on the HD-series pattern, the HD3100MA is expected to include live milling capability with C-axis. The 12-station turret accommodates both turning and live milling tools. Contact your Hyundai WIA dealer for specific live tooling specifications.
04
Most box-way turning centers in this size class run Z-axis rapids of 20-24 m/min. The HD3100A's 30 m/min Z-axis speed approaches linear-guide machine speeds, reducing the traditional cycle-time penalty associated with box-way construction. On programs with frequent tool changes and long Z-axis positioning moves, this translates to measurably shorter cycle times.
