What to Look for When Buying a Used Hankook
Hankook machines are built for heavy-duty turning and boring of large, heavy workpieces. Cast iron bed construction, hardened and ground slideways, and robust spindle assemblies give these machines the rigidity required for demanding applications. Here is what to inspect on used units.
On horizontal lathes, check the spindle, bed, and ways. Hankook lathes use large-bore spindles (up to 550 mm on the Protec 13N) driven by powerful AC motors. Test spindle runout at the chuck face and verify bearing condition. On Dynaturn models with 3-way bed construction, inspect slideways for wear or taper. Check bed straightness with a precision level. Verify tailstock alignment on long-bed machines.
On vertical boring mills, inspect the table, crossrail, and ram. Hankook VTB/VTC machines carry loads up to 50 tons on precision rotary tables. Verify table bearing runout and axial play. On machines with elevating crossrails (W-axis), test lift mechanism travel for parallelism. On VTC models, verify C-axis indexing accuracy and milling spindle runout. Inspect ram for scoring or gib wear.
On roll lathes, verify the steady rest and drive system. Hankook R-series roll lathes handle workpieces up to 150 tons across bed lengths up to 100 feet. Test steady rests for concentricity. Verify rated torque at low RPM for heavy interrupted cuts. Check bed and carriage for wear patterns typical of repetitive roll profiles.
Confirm the Fanuc control and tooling. Hankook machines use Fanuc CNC controls (18i-TB, 21i, 31i-A, 32i-A, 32i-TB depending on model and vintage). Verify the control boots cleanly, all axes home correctly, and the turret or tool post indexes reliably. On VTC models with automatic tool changers, cycle through every position. Test any optional equipment such as grinding attachments and angle heads.
Hankook Protec N-Series (Teach Lathes)
The Protec N-series (6N, 7N, 9N, 9NC, 11N, 13N) provides semi-CNC or "teach" lathe operation, combining the simplicity of manual-style controls with CNC positioning and programmability. Available with spindle bores from 4 inches through 21.6 inches, distances between centers up to 315 inches, and front and rear chuck options. The Protec 9NC (37.4-inch swing, 10-inch bore) is the most widely traded Hankook model on the used market. These machines are workhorses in oilfield, pipe threading, and general heavy-turning job shops.
Hankook Hanturn & Proturn Series
The Hanturn series (75, 85, 95, 105, 110, 130) delivers full CNC turning with Fanuc controls. Swing diameters range from approximately 750 mm through 1,300 mm. The BB550 (Big Bore) variant provides oversized spindle bore for oil country tubular work. The Proturn series (60, 60B, 90, 100) offers heavy-duty CNC turning for mid-range to large workpieces with rigid bed construction and high spindle torque.
Hankook Dynaturn Series (Heavy-Duty & Roll)
The Dynaturn series (1100, 1300, 1500, 1700) represents Hankook's heavy-duty CNC horizontal lathe platform, with swings up to 102 inches, bed lengths up to 394 inches, and wide 3-way bed construction for maximum rigidity under heavy cuts. The Dynaturn 20/22/24/26 extends capacity further. The Dynaturn R-series (11R, 13R, 15R) is purpose-built for steel roll turning with capacity up to 118-inch swing, 100 feet between centers, and 150-ton workpiece weight. Matching steady rests, lunettes, and specialized tooling are integral to roll lathe applications.
Hankook VTB & VTC Vertical Boring/Turning Mills
The VTB (boring) and VTC (boring with C-axis and milling) series covers table diameters from 1,000 mm through 5,000 mm. Standard models (VTB/VTC 100 through 160) handle mid-size components. The E-series (125E through 200E) adds enhanced crossrail and turning height. Large-format models (3040E through 5060E) handle tables up to 5,000 mm with workpiece loads to 50 tons. The Y-series adds Y-axis for off-center machining operations. VTC models offer ATC (up to 24 positions), C-axis, live milling spindle, grinding attachments, and angle head capability.

Frequently Asked Questions About Used Hankook Machines
Are used Hankook machines reliable?
Yes. Hankook has specialized in heavy-duty lathes and vertical boring mills since 1969, with over 3,000 machines produced in the last decade alone. Cast iron construction, hardened and ground slideways, and Fanuc CNC controls deliver long service life in the most demanding production environments. The company exports to over 70 countries and maintains a strong service reputation.
What CNC control does Hankook use?
Hankook machines use Fanuc CNC controls exclusively. Depending on model and vintage, machines may be equipped with the Fanuc 18i-TB, 21i, 31i-A, 32i-A, or 32i-TB. Fanuc controls are among the most widely supported platforms in the industry, with extensive training and service resources available.
What should I inspect before buying a used Hankook?
On horizontal lathes, check spindle bore condition, bed straightness, and slideway wear. On VTLs, verify table bearing runout, crossrail parallelism, and ram condition. On roll lathes, test steady rests and low-RPM torque. For all models, confirm Fanuc control function and cycle the tooling system.
What Hankook models hold their value best?
Protec 9NC teach lathes, Dynaturn heavy-duty CNC lathes, and VTB/VTC vertical boring mills maintain strong resale values. Machines with large spindle bores, long bed lengths, and VTC milling capability command premiums. Call (844) 478-8181 for current valuations.
