What to Look for When Buying a Used SMART Machine Tool
SMART Machine Tool machines are relatively young in the used market (first deliveries April 2019) which means most units come in good operational condition with their original Fanuc 31i-B controls and box-way construction intact. A well-maintained SMART delivers reliable production service. Here is what to inspect on used units.
Inspect the box ways and ballscrews. SMART's defining mechanical feature is heavy-duty box-way construction across the NL lathe lineup and core VMC platforms. Check the ways for wear, scoring, and confirm the central lubrication system delivers oil to all sliding surfaces. Verify gib adjustment. On linear-guideway models, inspect rails, blocks, and rail covers. Check ballscrew backlash on all axes and confirm no loss of preload.
Verify the spindle, chuck, and turret. On NL lathes, test main spindle runout, listen for bearing noise across the full RPM range (NL 2500: 4,000 RPM, 47 HP), and verify chuck clamping at rated hydraulic pressure. Cycle the turret through all positions and check indexing accuracy. On live-tooling LM models, verify each driven tool position. On NX HMCs and SV/SX VMCs, test the spindle (CAT 50 on NX 5000 at 12,000 RPM, CAT 40 on smaller models), cycle the ATC through every pocket, and verify coolant-through-spindle if equipped.
Check axes, rapids, and feed rates. Run each axis through full travel at rapid (NX 5000 rapids to 1,968 IPM) and confirmed feed rates. Listen for backlash, missed steps, or unusual noise. Verify travel distances match spec (NX 5000: 31 x 29 x 32.7 inches; NL 2500: 27.56 inch swing, up to 29.53 inch turning). Check that chip auger, way covers, and any pallet changer or fourth axis function correctly.
Identify the Fanuc 31i-B control and conversational programming. All SMART machines ship with Fanuc 31i-B standard, including Manual Guide i conversational programming. Confirm the control boots, software is current, parameters are backed up, and installed options (rigid tapping, probing, high-pressure coolant interface, tool monitoring) function. SMART's Wisconsin operations stock spare parts for next-day shipping; verify any service history.
SMART Machine Tool Machine Series
NL Series CNC Lathes (Bestseller)
The NL Series is SMART's flagship box-way 2-axis CNC lathe platform, widely traded and the brand's anchor product. The NL 1500 (6" chuck) is compact. The NL 2000 (8" chuck) and NL 2000B (10" chuck) cover mid-size turning. The NL 2500/750 and NL 2500/1100 feature 47 HP spindle, 4,000 RPM, 27.56 inch swing, and up to 29.53 inch turning length. The NL 3000B (12" chuck) handles larger work, and the NL 5000LM and 6000LM add live tooling for compound machining.
NX Series Horizontal Machining Centers
The NX Series delivers heavy-duty HMC production. The NX 5000 features 31 x 29 x 32.7 inch travels, 20-inch compact table, 12,000 RPM CAT 50 spindle with 310 ft-lb torque, 1,968 IPM rapids, and a 60-tool magazine for high-volume multi-tool setups. The NX 7000 scales up for larger workpieces and pallets.
NV, SV & SX Vertical Machining Centers
The NV Series, SV Series (including the popular SV2), and SX Series (including the SX 4000) cover SMART's vertical machining lineup. These VMCs serve job shop and contract manufacturing roles where precision and throughput matter, all standard with Fanuc 31i-B and Manual Guide i.
KM, KT & HSA Compact Platforms
The KM Series (KM 450D) provides compact CNC milling. The KT Series (KT 360D) covers compact turning. The HSA Series rounds out specialty production turning. These compact platforms suit small job shops and prototype work where floor space is limited.
How to Sell Your Used SMART Machine Tool
SMART CNC machines hold strong resale value thanks to the active Wisconsin parts and service operation, recent fleet age (most units 2019 or newer), and steady demand from contract manufacturers and job shops. NL lathes and NX HMCs are in particularly steady demand.

Frequently Asked Questions About Used SMART Machine Tool Machines
Who owns Smart Machine Tool?
Smart Machine Tool Korea is owned by US-based Dynamic International. The company opened its 90,000+ sq ft Korean factory in 2019, with US operations in Wisconsin. Dynamic International brings over 100 years of combined machine tool experience and designs the machines specifically for the American market.
Are used SMART Machine Tool CNC machines reliable?
Yes. SMART machines feature heavy-duty box-way construction (NL lathes and most VMCs), Fanuc 31i-B controls, and were designed for the American market. The brand has shipped 850+ machines into North America since 2019 with strong customer support and parts availability. Most used SMART machines are recent vintage with low to moderate hours.
What CNC control does SMART use?
All SMART machines come standard with the Fanuc 31i-B CNC control and Manual Guide i conversational programming. Consistent across NL lathes, NX HMCs, NV/SV/SX VMCs, and KM/KT compact platforms, simplifying operator training and programming across a SMART fleet.
What is the NL 2500 known for?
The NL 2500/750 and NL 2500/1100 are the NL Series workhorses with 47 HP spindle, 4,000 RPM main spindle, 27.56 inch swing, up to 29.53 inch maximum turning length, and 10-inch chuck. Box-way construction suits heavy material removal and consistent production accuracy.
Where are SMART machines made?
SMART machines are built in a 90,000+ sq ft factory in Daegu, South Korea owned by Dynamic International. Production runs at approximately 80-100 machines per month. US support and spare parts ship from a 25,000 sq ft Wisconsin facility.
What should I inspect on a used SMART?
Box-way condition and lubrication, spindle runout and bearing health, turret indexing on lathes, ATC function on machining centers, ballscrew backlash, axis motion through full travel, and Fanuc 31i-B control boot and parameter backups. Verify any documented service history with SMART's Wisconsin support team.
