~$37,800 to ~$99,500 used. Spindle economics match the VF-series ($4,800–$7,200 rebuild vs $16,000–$24,000 replace); the 1,000 PSI through-spindle coolant makes the rotary-union seal a scheduled wear item and a real bearing-killer. Also inspect the pallet changer and 4th-axis for backlash.

As of Sep 11, 2026What can make the cheap machine expensive?
| Component | Severity | Documented repair cost |
|---|---|---|
| Spindle bearing | high | $4,800–$24,000 |
| Coolant intrusion into spindle | high | not yet verified |
Haas VF/EC-series spindle economics: rebuild $4,800–$7,200, replacement spindle $16,000–$24,000 before install. Runout under 0.0002" pre-failure is a rebuild candidate; above 0.0005" the shaft may be compromised. Check spindle runout and listen for grinding/whining at high RPM before buying.
$4,800–$24,000EC-400PP units run 1,000 PSI through-spindle coolant; high-pressure rotary-union seals are a scheduled wear item and a documented coolant-intrusion path that ruins bearings. Verify seal condition and TSC pressure.
Cost not yet verifiedInspection point (not independently sourced this pass): on this twin-pallet HMC, check pallet indexing/clamping repeatability and the rotary (B-axis) table for backlash — the pallet changer and rotary are the HMC-specific wear items. Treat as a pre-purchase check, not a documented defect.
Cost not yet verifiedA Haas VF-series rebuild has come in between $4,800 and $7,200 … a replacement spindle for the same machine … runs $16,000 to $24,000 before install.

From the research record
- PRICE (SECONDARY, Machinio aggregate + live listing, as-of 2026-09-11): 2004–2005 $37,800–$50,500; 2006 $39,750; 2008 $49,900; 2013 $99,500; EC-400PP 2012 (probing, 1000 PSI TSC, 70A) contact-for-price (https://www.machinio.com/models/haas/ec-400). Machinio bands are multi-listing aggregates; observations is a floor.
- POWER: HMC with pallet changer — high amperage (listings show 70 A), 3-phase, heavy; professional rigging and leveling required.
- CONTROL: proprietary Haas control; Fanuc lifetime-support contrast applies.
