What to Look for When Buying a Used Tongtai
Tongtai is one of Taiwan's largest machine tool builders, with more than five decades of production and a reputation for solid Meehanite castings, linear-guideway construction, and well-integrated controls. A properly maintained Tongtai delivers years of reliable service. Here is what to verify on used units.
Inspect the spindle, ATC, and tool changer. Test spindle runout at the nose, listen for bearing noise across the full RPM range, and check thermal stability after warm-up. Cycle the automatic tool changer through every pocket. On 40-taper TMV-series machines, check the BT or CAT pull-stud condition; on 50-taper VP-series machines, verify the heavier drawbar and clamping pressure. On twin-spindle FV machines, verify both spindles operate to spec.
Verify axis motion, linear ways, and ballscrews. Tongtai builds with large pre-tensioned ballscrews and high-grade linear ways. Run each axis through its full travel at rapids and feed rates. On TMV 40/50 taper VMCs, rapids reach up to 48 m/min on smaller machines and 18 m/min on larger ones. Check for backlash, missed steps, or unusual noise and verify lubrication function.
Check the table, work envelope, and rotary or trunnion units. On TMV-1100A and TMV-1500A large-table machines, verify table flatness and T-slot condition. On VTX and QVM milling and tapping centers with rotary pallet changers, time the pallet swap and verify both pallets clamp accurately. On CT, MDV, and GT 5-axis trunnion machines, check trunnion calibration, brake function, and simultaneous motion.
Identify the CNC control and software. Tongtai machines ship with Fanuc, Mitsubishi, Siemens, or Heidenhain controls based on customer order. Confirm the control series and software version, verify custom macros, options, and probing routines transfer with the machine, and check that machine parameters are backed up.
Tongtai Machine Series
TMV Series (Best-Selling VMCs)
The TMV series is Tongtai's most widely deployed platform. The TMV-720A, TMV-850QII, TMV-1050QII, TMV-1100A, and TMV-1500A deliver rigid Meehanite construction, linear-guideway travel, and rapid traverse up to 48 m/min. These are the workhorses of Tongtai's automotive and mass-production customer base.
VP, FV & Tapping Center Series
The VP series (VP-8, VP-10) is Tongtai's heavy-duty high-speed VMC for mass production. The FV series offers single and twin-spindle VMCs for high-volume parts in automotive, appliance, electronics, and energy. The VTX, QVM, and TMV 30/40-taper milling and tapping centers serve high-volume drilling and tapping with rotary pallet changers for fast workpiece swaps.
5-Axis Machining (CT, MDV, GT Series)
The CT series high-speed 5-axis trunnion-table machining centers are engineered for complex mold, die, aerospace, and medical parts. The MDV and GT series extend the trunnion-table 5-axis lineup with multiple sizes and spindle options.
TMH Horizontal Machining Centers
The TMH series (TMH-400, TMH-500) covers horizontal machining without pallet changers, with X-Y-Z travels around 500 mm for general HMC production work.
TC, TMS & TMT CNC Lathes
The TC-2000 and TC-2500 are 30-degree slant-bed CNC lathes with precision linear ways and large servo motors. The TMS series (TMS-2000, TMS-2500, TMS-3000, TMS-3800) covers 8-inch through 15-inch chuck sizes. The TMT-2000 features a 75-degree mono-block slant-bed cast from Meehanite iron for maximum rigidity.
Multi-Tasking, Ultrasonic & Specialty
Tongtai also builds multi-tasking turn-mill centers, ultrasonic-assisted machining centers for hard and brittle materials, 6-axis PCB drilling and routing machines, and metal powder-bed-fusion additive systems including the AM-250 and AMP-160.
How to Sell Your Used Tongtai

Frequently Asked Questions About Used Tongtai Machines
What is the relationship between Tongtai, TTGroup, Honor Seiki, and APEC?
Tongtai Machine & Tool is the flagship company of TTGroup. Honor Seiki (vertical turning lathes), APEC or Asia Pacific Elite Corp. (gantry and bridge machining centers), and Quicktech (small high-speed lathes) are sister brands within TTGroup, along with PCI SCEMM in France and Anger Machining in Austria.
Are used Tongtai machines reliable?
Yes. Tongtai has built machine tools since 1969 and is the largest publicly listed machine tool maker in Taiwan by revenue. The TMV series has been deployed across automotive, aerospace, medical, and electronics production for decades with a strong reputation for rigidity, repeatability, and longevity.
What CNC control does a Tongtai use?
Tongtai machines are built to order and ship with Fanuc, Mitsubishi, Siemens, or Heidenhain controls. The control choice affects training, programming, and parameter portability, so verify the exact control series and software version before purchase.
What should I inspect on a used Tongtai?
Spindle runout and bearing condition, ATC function, axis motion through full travel, linear ways and ballscrew condition, lubrication system, table flatness, and any rotary pallet, trunnion, or twin-spindle features. Confirm the control series, software version, and that parameter backups transfer with the machine.
What Tongtai models hold their value best?
The TMV-720A, TMV-850QII, and TMV-1050QII are perennially strong on the used market thanks to massive installed base. CT and MDV 5-axis machines hold a premium for mold, die, and aerospace work. Call (844) 478-8181 for current valuations.
