How CNC lathes are calibrated?

CNC lathes are calibrated by first ensuring the machine is level and properly aligned, often using precision measuring tools like dial indicators. The calibration process typically involves verifying and adjusting the machine's axes for accuracy, checking the tool offsets, and ensuring that the spindle speed and feed rates are correctly set. Additionally, a test cut may be performed to assess accuracy, followed by adjustments based on the results. Regular maintenance and recalibration are essential to maintain precision over time.
