PQI uses an Advanced Renishaw laser interferometer for linear and rotary calibration as well as a Renishaw ball bar.

If you have concerns regarding your spindle health, PQI also offers complete spindle analysis, utilizing the Lion Precision Spindle Check Analyzer for vibration, runout and speed and spindle growth.

To provide a calibration service quote, we need the manufacturer and model of the machine tool, the type of control and its software version. We also need to know if you have any other requirements including analysis of straightness, squareness, pitch and yaw.
