Spindle Test Room Area

Our experienced team subjects every repaired spindle to a comprehensive array of functional and diagnostic checks. We log performance data and run the spindle through its full operating range to include tool changes, ramp up and ramp down cycles monitoring for stability and precision. Testing of the spindle includes the following:

• Motor Components: Full static and functional testing of the motor to verify current draw, thermal stability, and temperature saturation through all speed ranges.

• Clamping System Integrity: Verification of the drawbar, springs, and gripper set to ensure precise and repeatable tool clamping force and consistent runout.

• Cooling Systems and Process Cooling: Pressure testing and dynamic testing of all circuits to include the motor cooling, bearing cooling, process cooling and through spindle cooling.

• Mechanical Structure: Dimensional and performance verification of the pertinent features of the spindle housing, rear connection plate and interfaces to the machine tool.

• Sensor Systems and Diagnostics: Calibration and validation of all integrated spindle sensor systems, including the encoder, clamping sensors, vibration sensor, shaft growth sensor, and bearing/stator temperature sensors.

• Ancillary Functions: Full operational checks of the unclamping unit (hydraulic seals, piston) and the rear cover (fittings, cables, connectors) to ensure seamless integration with your machine.

Only after a spindle successfully completes this final, exhaustive test—and the results meet our stringent quality standards—is it approved for shipment.
