Measurement of thermal expansion of the spindle eddyNCDT SGS4701
Non-contact and non-wear measurement is possible.
The displacement measurement system SGS 4701 (Spindle Growth System) was developed for use with high-speed spindles. In milling equipment, it is necessary to correct for changes in spindle length caused by high rotational speeds and heat generation to keep the tool in a defined position. The SGS sensor detects the spindle expansion due to this heat and centrifugal force. Measurements are typically taken on the labyrinth ring, and in addition to changes in length, the sensor's temperature is also detected and output. The measurement values are sent to CNC control to correct any positional deviations.
