CNC spindle repair typically costs between $500 and $6,000, depending on the spindle brand, model, extent of damage, and the service tier you choose. As a benchmark, professional repair runs 25–35% of the cost of a new spindle — making it the right choice in the vast majority of cases.
At HS Spindles, we repair high-speed CNC spindles across all 50 states. We give you a written cost estimate before any work begins — free of charge. Here is exactly what drives spindle repair pricing and what to expect at each level.
What Does Spindle Repair Cost by Service Tier?
HS Spindles offers three repair tiers. All include the same full rebuild standard — the difference is turnaround time and prioritisation.
| Service Tier | Turnaround | Relative Cost | Best For |
| Economy Repair | 5–8 weeks | 15% less than standard | Non-urgent, budget-sensitive jobs |
| Standard Repair | 2–3 weeks | Standard rate | Planned maintenance windows |
| Expedited Repair | Same week | Premium rate | Machine down, urgent production |
A typical standard CNC spindle repair — full disassembly, bearing replacement, dynamic balancing to ISO G1.0, and runout certification — runs in the following ranges by spindle type:
- Compact routing spindles (HSD, Hiteco ISO30): $500–$1,800
- Mid-range ATC spindles (HSD ES series, Hiteco QE/QT): $800–$3,000
- High-speed precision spindles (GMN TSSV, Setco grinding): $1,500–$6,000
- CNC machining centre motors (Fanuc alpha/beta, Mitsubishi): $1,000–$5,000
- Premium multi-tasking spindles (Mazak Integrex, DMG Mori): $2,000–$8,000
These are general ranges. Your actual quote depends on what the inspection finds.
What Factors Drive Spindle Repair Cost?
- Spindle brand and model
High-speed precision spindles — particularly GMN ceramic bearing models or Setco grinding spindles — require more precise assembly processes and specialist bearing sets. This is reflected in cost. A standard HSD ES919 repair costs considerably less than rebuilding a GMN TSSV running at 60,000 RPM.
- Extent of the damage
A straightforward bearing replacement with no secondary damage is the lowest-cost scenario. Additional charges apply when inspection finds:
- Shaft damage: grinding or replacing a damaged shaft adds $400–$2,000 depending on size
- Taper regrinding: restoring a worn tool interface adds $300–$800
- Housing bore repair: $300–$600
- Motor winding repair (Fanuc/Mitsubishi): $500–$1,500
- Encoder replacement: $200–$600
This is why we diagnose before we quote — the teardown tells us what you are actually dealing with.
- Bearing specification
Standard angular contact bearings (steel) are lower cost. Ceramic hybrid bearings — required for GMN and some other ultra-high-speed models — cost more due to the bearing itself. We use super-precision bearings from SKF, FAG, and NSK as standard.
- Service tier selected
Expedited repair carries a premium because it goes to the front of the queue and may require overtime. Economy repair is 15% less than standard but takes 5–8 weeks. Repair vs Replacement: What Does It Actually Save? A new OEM CNC spindle typically costs $8,000–$30,000 depending on brand and model, with lead times from 4 to 32 weeks. Repair at 25–35% of that cost means:
| New Spindle Cost | Repair Range (25–35%) | You Save |
| $10,000 | $2,500–$3,500 | $6,500–$7,500 |
| $20,000 | $5,000–$7,000 | $13,000–$15,000 |
| $30,000 | $7,500–$10,500 | $19,500–$22,500 |
In most cases, repair is the financially correct decision — particularly for newer spindles that have failed due to bearing wear rather than structural damage.
Does Spindle Brand Affect the Repair Cost?
Yes. Here is a general cost comparison across the brands we repair most frequently:
HSD Spindles — $600–$2,500 for standard repair. HSD is our most frequently serviced brand. We stock common HSD bearings, which reduces turnaround time and can reduce cost. Complex ES-series ATC models with drawbar work run toward the higher end.
Hiteco Spindles — $700–$2,800. Similar to HSD. QT series for stone cutting tend to run slightly higher due to heavier-duty components. We stock Hiteco bearings and supply Hiteco aggregates, which means faster parts availability.
GMN Spindles — $1,500–$6,000. GMN’s ultra-high-speed ceramic bearing spindles require tighter assembly tolerances and specialist bearing sets. The rebuild process is more involved. Worth it: a new GMN spindle can cost $15,000–$50,000.
Setco Spindles — $1,200–$5,500. Precision grinding spindles with exacting runout tolerances. Certified to better than 0.0001″ (2.5 micron) runout after rebuild. We document and certify the measured runout values.
Fanuc Spindle Motors — $1,000–$4,500. Alpha and beta series motor repairs typically involve bearing replacement and often encoder replacement. We test at full operating speed before return.
Mazak Spindles — $1,500–$7,000 depending on model. Mazak’s Integrex and Nexus series machines represent $200,000+ investments — repair is almost always the right decision.
Is the Diagnosis Free?
At HS Spindles, yes. We inspect every spindle and provide a written failure analysis and cost estimate before any repair work begins. There is no charge for the diagnosis — you decide whether to proceed based on the quote.
If the spindle is beyond economical repair, we tell you honestly and can often help source a refurbished replacement.
Frequently Asked Questions
How much does a basic spindle bearing replacement cost?
A straightforward bearing replacement on a standard CNC routing spindle (HSD, Hiteco ISO30, etc.) typically runs $500–$1,200 at HS Spindles. This includes disassembly, bearing replacement with super-precision bearings, dynamic balancing, runout test, and reassembly. Complex spindles or those with secondary damage will be higher.
Is spindle repair worth it, or should I just buy a new spindle?
In the majority of cases, repair is worth it. Repair typically costs 25–35% of a new spindle and takes 1–3 weeks vs 4–32 weeks for a new OEM unit. The only case where replacement makes more sense is when the spindle has severe structural damage (cracked housing, broken shaft) that would cost more to repair than replace, or when the model is obsolete with no parts availability.
Do I get a fixed price or an estimate?
We provide an estimate range after initial inspection (free), then a fixed written quote after teardown. The teardown reveals the actual condition of all internal components, which is when we can confirm the exact price. You approve the fixed quote before we proceed.
Does the repair come with a warranty?
Yes. All repairs at HS Spindles include a standard warranty. Ask us for current terms when you request your quote.
