Restless Machines: WHO WE ARE
Precision Repair. Documented Results. Long-Term Reliability.
Restless Machines was founded on one principle: CNC spindle and turret repair should be done right the first time. Our lead technician Rouven Strothmann trained through Germany’s rigorous technical apprenticeship system and holds DMG certification — a standard rarely found in the American repair market.
Every rebuild we perform is documented. Every component is measured. Every spindle leaves our facility with a complete disassembly report and a final rebuild report — so you know exactly what was done and why.
We are not a generalist repair shop. CNC spindle and turret repair is what we do.
- German engineering training — DMG certified
- Two written reports on every rebuild
- Root-cause diagnostics, not temporary fixes
When a spindle fails, the cost is not just the repair — it is every hour your machine sits idle. Restless Machines brings German engineering standards to CNC spindle rebuilding, diagnosing the root cause before rebuilding begins.
We repair motorized, belt-driven, and gear-driven spindles from Mazak, DMG Mori, Doosan, Makino, Haas, Okuma, and Kessler.
- Complete disassembly inspection report
- High-precision bearing installation
- Dynamic balancing at operating speeds
- Final rebuild report with warranty
Turret problems get worse with production. Restless Machines specializes in CNC turret repair for all major systems, diagnosing the mechanical and hydraulic root cause — not just the symptom.
All turret repairs include a one-year warranty on workmanship and replaced components.
- Sauter
- Duplomatic
- SMW Autoblok
- And much more
Our 6-Step CNC Spindle Rebuild Process
Incoming Inspection
We measure runout, vibration, bearing condition, and taper integrity before disassembly begins. Every finding is recorded.
Full Disassembly
The spindle is fully stripped. All components are cleaned, measured, and evaluated — nothing is assumed serviceable without verification.
Disassembly Report
You receive a detailed written report documenting every component’s condition, all required repairs, and our recommended rebuild scope. No surprises.
Bearing Replacement
High-precision spindle bearings and seals are installed in a controlled, clean environment to protect critical tolerances.
High-Speed Balancing
The assembled spindle is dynamically balanced at operating speed — eliminating vibration at the source, not masking it.
Final Report
The rebuilt spindle is tested under load. You receive a final rebuild report with measurements, test results, and warranty documentation.

Every major CNC platform
Restless Machines repairs CNC spindles and turrets across all major machine tool platforms. Whether you run a Mazak turning center, a Haas VMC, a DMG Mori 5-axis, or a Makino horizontal — our technicians have the hands-on experience to diagnose, rebuild, and return your spindle to factory specification. We stock common bearing sets for the most popular platforms, which means faster turnaround and fewer delays.

— Why Restless Machines
A specialist team — not a factory
We focus exclusively on CNC spindle and turret repair. That specialization means faster diagnosis, more accurate rebuilds, and fewer repeat failures — because our technicians have seen your exact failure mode before.
Precision diagnostics first
Before we disassemble anything we run full vibration analysis, runout measurement, and bearing inspection — so we know exactly what failed and why.
Every rebuild documented
You receive a disassembly inspection report and a final rebuild report with measurements and test results — every single time, no exceptions.
24-hour evaluation turnaround
We evaluate and contact you within 24 hours of receiving your spindle. Rush service available when every hour of downtime costs you money.
Nationwide shipping
We serve manufacturers across the entire USA. We provide packaging guidance and can arrange freight pickup for larger spindles and turrets.
Industries We Serve
CNC spindle accuracy and machine uptime are not optional in these sectors. We serve manufacturers where the cost of failure is high and the tolerance for shortcuts is zero.
