What to Look for When Buying a Used Nakamura-Tome
Nakamura-Tome machines are among the most productive CNC lathes ever built, and the multi-spindle, multi-turret architecture demands a more thorough inspection than a conventional lathe.
Inspect both spindles on twin-spindle models. On WT, WY, NTY3, NTJX, and Super NTJ platforms, the main and sub spindles must hold runout independently and synchronize cleanly for part transfer. Measure runout across the full RPM range, listen for bearing noise at top speed, and verify the phase-synchronized handoff under load. Vibration during transfer or any synchronization error is a red flag.
Check every turret and live-tool station. Nakamura-Tome's signature is two or even three turrets working simultaneously. Verify indexing repeatability on each turret, check for play in the curvic coupling, and rotate every live-tool station under power to confirm driven-tool torque, runout, and coolant delivery. Missing live tools, damaged collets, or sluggish indexing are common on high-hour machines and expensive to restore.
Verify Y-axis and B-axis condition. On WY, NTRX, NTJX, Super NTJ, and Super NTMX machines, the Y-axis and B-axis milling spindle carry the bulk of off-center and contoured work. Check Y-axis ballscrew backlash, B-axis clamp repeatability and angular positioning, and milling-spindle runout. These axes see the hardest loads on mill-turn machines.
Identify the control generation. Nakamura-Tome runs on Fanuc hardware with Nakamura's proprietary interface: older machines use NT Work Navigator, mid-generation use NT Nexus, and newer use NT Smart X. The Fanuc platform (16i, 18i, 30i, 31i, 32i) affects parts availability and operator training.
Nakamura-Tome Twin-Spindle Lathes
WT Series (Twin-Spindle, Twin-Turret)
The WT series (WT-100, WT-150, WT-250, WT-300) is Nakamura-Tome's flagship twin-spindle twin-turret platform and the most commonly traded family on the used market. Two opposed spindles and two independent turrets allow both sides of a part to be machined simultaneously. The WT-250 and WT-300 are the most popular sizes for mid-range production.
WY Series (Twin-Spindle with Y-Axis)
The WY series (WY-100, WY-150) adds full Y-axis capability to the twin-spindle twin-turret architecture, enabling off-center milling, contoured surfaces, and complex prismatic features. A preferred choice for medical and hydraulic component work.
NTY3 Series (3-Turret Turning)
The NTY3-100 is the industry's only 3-turret CNC turning center, pairing twin opposed spindles with three independent turrets for maximum simultaneous metal removal. Extremely productive on complex parts where cycle time drives profitability.
Nakamura-Tome Multi-Tasking Mill-Turn
NTRX, NTJX & NTJ Series
The NTRX-300, NTJX, and NTJ-100 combine full turning, B-axis milling, Y-axis, and sub-spindle capability for complete single-setup machining. These platforms replaced earlier NT mill-turn models and are heavily represented in aerospace and medical job shops.
Super NTJ & Super NTMX Series
The Super NTJ and Super NTMX are Nakamura-Tome's large-envelope multi-tasking platforms, handling larger workpieces with higher-torque milling spindles and extended Y-axis travel. Popular in oil and gas, defense, and heavy hydraulic component manufacturing.
Nakamura-Tome Single-Spindle Lathes
AS Series & SC Chuckers
The AS series (AS-150, AS-200, AS-200LM, AS-250) delivers single-spindle CNC turning with optional live tooling (LM models). The SC series (SC-200, SC-300) offers high-production CNC chuckers. Both lines share the heavy cast bed and precision spindle design used across the twin-spindle lineup.
How to Sell Your Used Nakamura-Tome
Nakamura-Tome machines hold strong resale value because of the brand's limited production volume, premium build quality, and multi-spindle architecture no other builder matches at the same scale. Demand is strongest on WT, WY, NTY3, NTRX, and Super NTJ models.

Frequently Asked Questions About Used Nakamura-Tome Machines
Are used Nakamura-Tome machines reliable?
Yes. Nakamura-Tome builds approximately 1,000 machines per year, prioritizing precision and quality over volume. Cast-iron beds, high-rigidity structures, and Fanuc drive systems give these machines long production lives, with WT and SC machines commonly holding tolerance after 20+ years of service.
What CNC control does Nakamura-Tome use?
All Nakamura-Tome machines use Fanuc as the underlying control, paired with Nakamura's proprietary operator interface. Older machines use NT Work Navigator, mid-generation use NT Nexus, and current machines use NT Smart X.
Twin-spindle vs single-spindle Nakamura-Tome models?
Twin-spindle machines (WT, WY, NTY3, NTJX, Super NTJ) have two opposed spindles and typically two turrets, allowing simultaneous front and back machining in one cycle. Single-spindle machines (AS, SC) offer a simpler, lower-investment platform for straight turning or basic live-tool work. Twin-spindle models command higher resale values.
What should I inspect before buying a used Nakamura-Tome?
Focus on spindle runout on both spindles, turret indexing repeatability, live-tool station condition, Y-axis and B-axis backlash, and phase-synchronized spindle transfer. Confirm control generation and Fanuc base hardware.
What Nakamura-Tome models hold their value best?
The WT series (especially WT-250 and WT-300), WY-150, NTY3-100, NTRX-300, NTJX, and Super NTJ platforms maintain the strongest resale values. Machines with Y-axis, sub-spindle, and higher live-tool counts command a premium. Call (844) 478-8181 for current valuations.
What industries use Nakamura-Tome machines?
Automotive tier suppliers, aerospace component shops, medical device manufacturers, hydraulic and fluid-power producers, oil and gas fitting makers, and high-mix precision contract shops, where cycle time and complete-part machining drive profitability.
