Spindle Check Analyzer
The SpindleCheck is a hardware and software package for measuring the dynamic performance of machine tool spindles.
SpindleCheck uses noncontact, capacitive sensors to measure error motions as changes in position of a precision target pin installed and rotating in the machine spindle.
The pin includes a copper strip used to trigger a once-around index pulse. This index sets a reference for angular location of the spindle to align measurements from multiple rotations.
The measurements are collected and analyzed by the SpindleCheck software. The results of the live measurement or archived measurement file are presented on polar and linear plots with calculated values of standard error motion measurements.
