Spindle Error Analyzer: Tests Performed-
Axial

Axial Error Motion acquires distance data from one probe in the Z axis (typically channel 3). The probe measures the axial motion of the spindle. Angular position data is also required and is obtained from the eccentricity motion measured by another probe in the X or Y axes or an index or encoder signal. It measures changes along the axis line and evaluates the following aspects of machine tool performance:

Performance Parameter	Related Source Problems
Surface finish capability	Bearing wear Improper preload Structural vibration
Performance degradation at specific speeds	Inadequate stiffness Imbalance Resonant frequencies of machine

 

Data Collected	Calculated Values
Z (One Probe)	Fundamental Residual Error Total Error Asynchronous Error RPM
