About the Mazak spindle
Mazak is a Japanese leader in CNC machine manufacturing, renowned for innovation and high-quality technology. The company offers versatile spindle solutions, valued for precision, durability, and performance, meeting the demands of advanced manufacturing plants worldwide.
Diagnostics, Disassembly, and Technical Analysis of Mazak Spindles
The repair process begins with detailed diagnostics to identify the cause of failure and assess the wear of individual components. We check radial and axial runout, rotor alignment, bearing condition, cooling, lubrication systems, and mechanical connections. At this stage, we also measure clearances, perform rotation tests, and inspect for leaks. After disassembly, we prepare a service report detailing the fault and proposed solutions.
Spindle Reception
- Device registration.
- Initial visual inspection (mechanical damage, overheating marks, oil/grease leaks).
Preliminary Diagnosis (without disassembly)
- Shaft runout measurement.
- Check of radial and axial play.
- Acoustic testing.
- Rotation test (if possible) – only for motor spindles with working drive.
Spindle Disassembly
- Disassembly into individual components.
- Damage documentation.
- Assessment of bearings, seals, rotor, shaft, taper, housing.
Cleaning and Technical Evaluation
- Ultrasonic or chemical washing.
- Component wear assessment.
- Identification of parts for replacement or refurbishment.
Quotation and Approval
- Service report and quotation.
- Waiting for customer approval.
Repair and Assembly
- Replacement of bearings, seals, socket refurbishment.
- Winding, sensor, encoder repairs (in motor spindles).
- Precise adjustment of clearances and alignment.
- Assembly in clean conditions with proper balancing.
Final Testing
- Vibration and noise measurement.
- Thermal and load tests.
- Electrical tests for motor spindles.
Final Report and Shipping
- Final documentation.
- Proper protection of the spindle for transport.
Refurbishment, Component Replacement, and Precision Alignment
Once the repair scope is approved, we proceed with servicing. We refurbish or replace worn Mazak spindle parts following original technical specifications. This includes replacement of precision bearings, bushes, seals, shaft alignment, mechanical repairs of housings, and dynamic balancing adjustments.
Final Testing, Documentation, and Service Warranty
After repair, the Mazak spindle undergoes extensive final testing. We conduct dynamic tests on test benches, measure vibration and noise, perform thermal tests, and check alignment accuracy. The spindle is run under simulated operating conditions to verify stability, performance, and sealing. Each repair is completed with detailed documentation confirming the quality of the work. We provide a service warranty on all repaired spindles.
Differences Between Classic Spindle and Motor Spindle Mazak
| Aspect | Classic Spindle | Motor Spindle |
|---|---|---|
| Drive | External (e.g., belt drive) | Built-in motor |
| Diagnostics | Primarily mechanical | Mechanical + electrical |
| Sensors/Electronics | None or minimal | Encoders, sensors, control system |
| Service Complexity | Low to medium | High – requires special tools and expertise |
| Balancing | Rotor and shaft | Entire motor-rotor unit |
| Spare Parts | Standard | Dedicated, hard to source |
| Repair Cost & Time | Usually lower | Usually higher – due to precision and electronics |
Summary
Service of classic Mazak spindles focuses on mechanical aspects – bearing replacement, clearance setting, cleaning. Motor spindle service also requires knowledge of electromechanics and electronics. Therefore, repair should be carried out in laboratory conditions with the highest precision and cleanliness.
