What to Look for When Buying a Used You Ji
You Ji machines are engineered for heavy-capacity work on oversized parts under sustained cutting loads. Rigidity, geometry, and spindle condition are the priorities on used units. Here's what to inspect before purchase.
On VTLs and VTCs, check table, ram, and crossrail geometry. Indicate the rotary table face for flatness and axial runout. Verify the ram for droop at full Z extension and check crossrail levelness across the full X traverse. On C-axis or live-tooling machines (VTC, VTM, YV series), cycle each live station under load and confirm clamp repeatability. Inspect way covers and ballscrew shields for chip and coolant damage. On ATC-equipped VTLs, cycle the full magazine and verify tool-change timing.
On horizontal boring mills, verify spindle, ram, and column squareness. Extend the boring bar to full Z and measure sag. Check ram squareness to the table across X, Y, and W. Test the spindle through its full RPM range for bearing noise, thermal growth, and draw-bar retention. On table-type models, indicate the B-axis rotary table for axial runout and indexing repeatability. Verify hydraulic clamp pressure on the ram and W-axis and confirm the counterbalance holds consistent pressure.
On double column machining centers, check bridge squareness and spindle condition. Measure X-axis straightness across the full bridge, Y and Z squareness to the table, and spindle runout at low and high RPM. Cycle the ATC and verify pocket alignment. On gantry models with automatic head changers, test each head attachment for repeatable docking and rigidity.
Match the CNC control to your shop. You Ji builds machines around Fanuc, Siemens, and Heidenhain controls depending on model and market. Fanuc is the most common in North America. Confirm the control generation, verify parameter and ladder backups, and check that any OEM macro customization is documented.
You Ji Vertical Turning Lathes
VTL Series (Heavy-Duty Vertical Turning)
The VTL series is You Ji's core vertical turning platform, available in single-column, double-column, and bridge-type configurations. Table diameters span from the VTL-1100 through the VTL-5000, with common mid-size models including the VTL-1600, VTL-2000, and VTL-2500. ATC, live tooling, and C-axis options extend VTL capability into full mill-turn territory. The VTL-1600ATC+C is among the most commonly traded used You Ji machines.
YV Series (Vertical Turning Centers)
The YV series (YV-800, YV-1000, YV-1200, YV-1600) integrates turning with live-tool milling in a compact footprint. Standard features include a BMT-style live turret or ATC magazine, C-axis indexing, and heavy-duty meehanite castings. YV machines handle complex, flanged, or bored workpieces in a single setup.
VTM and Extra-Large VTL
The VTM series adds full 5-face machining to the VTL platform with a crossrail-mounted milling head. Extra-large VTL-3000/4000/5000 models are bridge-type machines built for wind tower flanges, large ring gears, and energy-sector rotors.
You Ji Boring Mills and Double Column Centers
Horizontal Boring Mills
You Ji horizontal boring mills cover both table-type and floor-type (T-type) configurations. Common models include the MCH series (MCH-130/160/200/260) and the YB series. Spindle diameters range from 110mm to 260mm, with W-axis ram travels exceeding one meter on larger machines. Rotary tables, angle heads, and facing heads appear frequently on used examples.
Double Column Machining Centers
You Ji double column (bridge-type) machining centers include the MCV series and DCV series, with X-axis traverses from roughly two to ten-plus meters. Head options span vertical, right-angle, and universal automatic heads. These machines are staples in aerospace structural machining, large mold plate work, and heavy fabrication finishing.

Frequently Asked Questions About Used You Ji Machines
Are used You Ji machines reliable?
Yes. You Ji has built heavy-duty vertical turning and boring machines in Taichung since 1978, with oversized meehanite castings, hand-scraped slideways on precision models, and mainstream CNC controls. Well-maintained VTLs and boring mills routinely deliver 20-plus years of production service.
What CNC control does You Ji use?
Most You Ji machines sold in North America ship with Fanuc controls. European and specialty builds often use Siemens or Heidenhain. Verify the specific control generation (Fanuc 0i, 31i, or 32i) before purchase, since parameter files and ladder customization are model-specific.
Where are You Ji machines manufactured?
You Ji machines are built in Taichung, Taiwan, the center of Taiwan's precision machine tool industry. The company has operated since 1978 and ships to more than 50 countries.
What You Ji models hold their value best?
The VTL-1600ATC+C, VTL-2000, and VTL-2500 vertical turning lathes are the strongest holders of value in North America, followed by YV-1200 and YV-1600 VTCs and MCH-130 and MCH-160 boring mills. ATC and C-axis equipped machines command a premium over basic 2-axis configurations. Call (844) 478-8181 for a current valuation.
What industries use You Ji machines?
Wind energy (tower flanges, hub castings, main bearings), aerospace (landing gear, engine cases), oil and gas (valve bodies, flanges), mining, power generation, shipbuilding, and heavy machinery. Large swing capacity and high cutting torque make You Ji a strong fit for oversized, high-stock-removal parts.
Can You Ji machines run live tooling and full 5-sided machining?
Yes. YV-series VTCs and VTL machines with C-axis and live-tooling options deliver full mill-turn capability. VTM-series machines add a crossrail-mounted milling head for 5-sided machining of flanged and bored parts in a single clamping.
Does Resell CNC offer financing on used You Ji machines?
