Complete regeneration of a spindle for a 5-axis CNC machine

Our service received the HITECO QX-2 11/12 24 63F NC electrospindle, used in a five-axis CNC machining center. The unit, operating at 24,000 rpm with an HSK63F taper, showed signs of instability and system communication errors that made further operation impossible.

Electrospindle specifications:

  • Model: HITECO QX-2 11/12 24 63F NC

  • Tool taper: HSK 63F

  • Max speed: 24,000 rpm

  • Machine type: 5-axis CNC machining center

Diagnosis
and detected issues

During the initial diagnostics stage, we confirmed several key problems:

  • Damage to the electrical harness near the cooling channel transition,
  • A faulty inductive sensor responsible for spindle positioning,
  • Signs of improper balancing, causing vibrations during operation,
  • Elevated housing temperature under load — indicating potential communication errors with sensors or the cooling system.

Stages of service performed
for HITECO QX-2 11/12 24 63F NC electrospindle

The service process was divided into key stages, with full documentation for each of them:

1. Spindle disassembly and mechanical inspection
The spindle was fully disassembled and cleaned. Worn components and wires with visible insulation cracks were identified.
2. Replacement of the electrical harness
We installed a new, dedicated wiring harness with increased thermal resistance and improved flexibility in bending zones.
3. Installation of a new inductive sensor
The sensor was matched to the manufacturer's specifications and its signals verified in a test environment.
4. Communication circuit and sensor diagnostics
We performed signal line testing, voltage and resistance checks, and simulated working conditions.
5. Precision rotor balancing
Performed to 0.4G accuracy using our in-house balancing stations and certified protocol.
6. Load testing of the spindle
We verified speed ranges, noise levels, thermal stability, and bearing temperatures under test cycles.
7. Final parameter check and documentation
All values — from clamping force to axial runout — were verified and recorded in service reports.
8. Return of the electrospindle to the customer
The spindle was securely packaged, and the customer received full repair documentation and usage recommendations.

Why precision electrospindle service
matters

Servicing electrospindles like the HITECO QX-2 used in 5-axis machining centers requires precision, experience, and proper technical facilities. Unlike standard repairs, here even the slightest signal deviation or dynamic parameter anomaly can result in cutting errors, tool overheating, or costly production downtimes.
