Thermal drift is the biggest contributor to machining and part errors. SpindleCheck from Lion Precision measures changes in the point of machining as the spindle warms up, as chillers run and as the environment changes. Precise warm-up times can be determined for each machine tool and sources of thermal drift can be identified.
