Our Repair Process

Every spindle we service goes through a structured, documented process:

Complete disassembly and professional cleaning of all components
Metrological recording – all components within repair scope are measured and inspected
Precision reassembly with correct torques and bearing preload per manufacturer specifications
Original EMAG spare parts – all replacement parts are OEM and updated to current design standard
Lubrication applied to EMAG specification (grease type and quantity)
Test run on our test bench with full documentation of results

Test Bench Validation

Every reconditioned spindle undergoes a complete test run. The following parameters are measured and documented:

Parameter	Why It Matters for Your Production
Concentricity & axial run-out	Guarantees surface quality and dimensional accuracy
Balancing quality	Reduces vibration and extends tool and machine life
Hydrostatic flow rate	Maintains optimal lubrication and cooling in all conditions
Power consumption	Monitors efficiency and identifies friction losses
Temperature behavior	Prevents thermal issues during production
Electrical characteristics	Ensures compatibility with your machine system
