~$24,950 (1996) to ~$68,500 (2010); newer SS/CAT-50 units list higher (contact-for-price). Same VF-series spindle economics ($4,800–$7,200 rebuild vs $16,000–$24,000 replace, CAT-50 at the top), plus large-table way-cover wear. Check spindle and TSC rotary-union seal.

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. CAT-50 replacement spindles sit at the top of that band.
$4,800–$24,000SS/TSC units run through-spindle coolant; the rotary-union seal is a planned-maintenance item, not a repair item — a failed seal is a documented coolant-intrusion path that ruins bearings. Verify seal condition.
Cost not yet verifiedLarger telescoping way covers and X-axis cabling are documented Haas VMC wear items and cost more to replace at this size. Inspect covers and cable carriers.
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 listings, as-of 2026-09-11): 1996 $24,950; 1998 $32,500; 2006 $44,500; 2007 $59,500; 2010 $68,500; 2015 VF-6SS and 2020 VF-6 CAT-50 4-axis listed contact-for-price (https://www.machinio.com/models/haas/vf-6). Machinio bands are multi-listing aggregates; observations is a floor.
- CONTROL: proprietary Haas control; Fanuc lifetime-support contrast applies. 1996–1998 units run the oldest classic control — legacy board sourcing is the main obsolescence risk there.
