What Should I Pay Attention To When Buying a Second-Hand / used GOODWAY TA-32?
If you’re considering buying a second-hand GOODWAY TA-32 CNC lathe, there are many things to check. I pulled together what I could on its specs + what typically goes wrong with such machines. Use this as a guideline / checklist to decide whether the deal is good or what to look for carefully.
What the GOODWAY TA-32 Is (Typical Specs & Features)
First, here are what the TA-32’s approximate capabilities are (to help you know what it should do).
| Parameter | Typical / Known Value |
|---|---|
| Bar capacity (through-spindle) | ~ 32 mm |
| Maximum turning diameter | ~ 100 mm |
| Turning length / between centers | ~ 230-260 mm depending on variant |
| Spindle speed max | Around 6,000 rpm in many used machines listed |
| Spindle motor power | ~ 5.6-7.5 kW in many listings |
| Control system | Usually Fanuc (various series) in used ones |
| Tooling / Turret | Many TA-32 examples have an 8-position hydraulic turret, or combination gang + turret setup. |
Knowing those helps you check whether what you’re being offered matches in performance, or has been modified / degraded.
What to Pay Attention to / Inspect
Given that general spec, here are things to check carefully in a used TA-32. Many of these are common wear points or risk areas for small/medium CNC lathes of this class.
| Area | What to Inspect or Test | Why It Matters / Common Problems |
|---|---|---|
| Spindle & Bearings | • Run the spindle through its speed range, listen for noise, vibration, heat. • Check spindle run-out (use test bar + dial or electronic indicator). • Inspect condition of spindle nose (taper, wear, damage). • Check whether the bearings have been replaced/serviced; ask for history. | Spindle bearings wear out; run-out or vibration leads to poor finish. Taper damage can make tool holding poor. Replacement / repair can be expensive. |
| Guideways, Ball Screws / Feed Mechanism | • Move X & Z axes through full travel, feel for smoothness, binding, stick-slip. • Check backlash in axes (X and Z), whether within acceptable limit. • Inspect ways for wear, scoring, rust, unevenness. • Check lubrication system: are the ways / ballscrews properly lubricated; is automatic lubrication (if present) functioning. | Worn ways or screws degrade accuracy, cause chatter, reduce lifespan. Poor lubrication accelerates wear. |
| Turret / Tooling / Gang Slide | • Check turret indexing: speed, accuracy; tools hold tight; hydraulic locking works properly. • Inspect tool holders for wear. • If there’s a gang slide (knife holders, fixed tools), check for wear in those slides. • Check alignment of tooling: does the tool reach expected positions; is there tool chatter or misalignment in jobs. | Tooling misalignment or tool holder issues will degrade precision, increase scrap, reduce tool life. Turret lock issues can be dangerous / lead to errors. |
| Control, CNC, Software | • Identify exactly which Fanuc (or other) control; check that screen, buttons, feedback work. • Check error logs / fault history; any recurring alarms. • Check whether parts of the control (oscillator, servo drives, limit switches) have been replaced/maintained. • Check for available spare parts/licensing for that control version. • Test some programs or dry-runs to see motion behaviour. | A bad or partially failing control can be costly to repair; obsolete parts difficult to source. Control glitches may lead to crashes or precision errors. |
| Work Envelope / Capacity | • Confirm turning length (Z travel) and diameter actually match spec. Sometimes wear, or over-travel limits may have been imposed. • Check through-spindle bore matches spec, is clean, undamaged. • Check if chuck is included and condition of chuck jaws; whether the chuck holds work properly. • If tailstock is present, check its fit, alignment, whether quill moves smoothly. Many listings say “no tailstock” so you’ll want to know if you need one. | If the machine cannot accept the work size you need, or lacks a chuck or tailstock, then its usefulness is limited. Damage inside the spindle bore or to the chuck can affect concentricity and surface finish. |
| Electrical / Drives / Motors | • Check the spindle motor, axis motors/servos/amp drives for condition: noise, overheating, vibration. • Inspect wiring, connectors, look for signs of overheating, corrosion. • Check whether limit/home switches are working. • Check coolant / lubrication pump motors. • Check that the power supply (voltage) is appropriate where you are, and that transformer(s) (if needed) are present. | Electrical issues are often hidden until you run, then voltage drops, motors overheating, or drives failing cause downtime. Replacement of motors or drives can be expensive. |
| Coolant, Chip Removal, Lubrication | • Check coolant tank condition: clean, no rust, no sludge; good filtration; coolant pump working. • Check that chip tray / chip conveyor works properly; that guards are intact to prevent chips / swarf damaging moving parts. • Inspect lubrication of ways / ball screws; check whether oil levels maintained; automatic lubrication system (if installed) functioning. • Any leaks (hydraulic, coolant) in system. | Poor coolant or chip accumulation causes overheating, wear; leaks can mess with electricals. Lubrication integrity is critical for longevity. |
| Accuracy & Test Turning / Machining Performance | • Do test turning cuts: face, roughing & finishing pass; measure surface finish, dimensional accuracy. • Test repeatability: same dimension turned repeatedly, compare results. • Check taper on turned cylinders (run test along bed). • Check if accuracy remains near limits/exposure (e.g. near ends of travels). • Warm up the machine and test variation after some running. | Even if machine looks good, wear may have introduced errors. Real performance matters more than specs. Warm-up drift especially in older machines. |
| Wear, Usage & History | • Ask for how many hours active machining (not just powered on). • What materials have been used (e.g. steel vs aluminum vs hard materials). Heavy / abrasive or hard cutting wears tools, spindle, ways more. • Service / maintenance history: what’s been replaced, what’s been serviced. • Any past collisions / accidents. • Condition of consumables (tool holders, inserts, etc). • Whether the machine has been in a clean environment or heavy industrial (where dust, vibration, temperature swings affect condition). | A well-maintained machine will perform more reliably and cost less in unexpected repairs. Hidden damage (collisions, overuse) may degrade performance substantially. |
| Safety & Guards | • Inspect guard doors, interlocks: do they close, do they stop machine if opened. • Are moving (“hot”) parts guarded as required. • Are safety signs present; are emergency stops working. • Condition of guards / windows so operator can see inside safely. • Electrical enclosure integrity, grounding. • Compliance (or possibility to comply) with local safety / CE etc. | Safety is not only legal/regulatory, but also affects usability and insurance. Missing or broken safety features are risky and may cost to repair or retrofit. |
| Facility / Installation Issues | • Weight of the machine, required foundation; ensure your floor can carry it; ability to crane it in/out. • Power supply compatibility: voltage, phase, amperage. • Space for operations, maintenance, operator access. • Cooling / ventilation if machine emits heat, needs coolant / mist extraction. • Chip/swarf handling (chip conveyor etc.), disposal. | Getting it installed / aligned can cost considerably if infrastructure is insufficient. Poor environment can reduce lifespan or require extra investment. |
Red Flags / Things That Might Kill the Value
Here are things to watch out for that may mean huge extra cost or make the machine not worth the asking price:
- Spindle with excessive vibration or noise, or damaged bearings.
- Big run-out or taper error that cannot be aligned out.
- Major wear on ways / scour marks / pitting / rust that would require regrinding or replacement.
- Turret tool change / turret locking mechanism problems. If turret locking is weak, indexing slow or inaccurate.
- Missing or damaged chuck, or tooling holders, or significant accessories missing.
- Control system or electronics are obsolete / partly non-functional / no spare parts available.
- History of collisions or mechanical abuse. Even a hard tool crash can damage the turret, spindle nose, slide ways.
- Poor lubrication or signs of neglect: dried lubricant, rust, dirty coolant etc.
- Electrical issues: overheating, burnt cables, or previous “band-aid” repairs.
- Inaccurate work results; when you test, turned parts not within your tolerances.
- Hidden costs: transport, installation, alignment, calibration. If a machine is cheap but needs a lot to get working, the total cost may exceed a better maintained one.
How to Make a Good Decision
When evaluating a specific offer, you might:
- Bring a trusted technician with you, or ask for trial usage / test run.
- Ask for maintenance records; ask for photo / video of it running under load.
- Request measuring a known test piece (e.g. a cylinder or step gauge) to verify accuracy.
- Inspect tool holding (chuck, tool holders) since replacing those can be expensive.
- Check what accessories are included (chucks, tailstock if needed, tooling, wrenches, stand etc.).
- Figure out cost of spare parts locally (spindle bearings, servo drives, etc.).
