The SGS4701 displacement measuring system is developed specifically for high speed milling machine applications. Due to high machining speeds and the heat generated, the linear thermal expansion of the spindle in precision machine tools needs to be compensated for in order to keep the tool in a defined position at all times. The SGS sensor measures the thermal and centrifugal force expansion of the spindle. These measurement values are fed into the CNC machine tool as correctional values, compensating for any positioning errors. The SGS4701 uses the eddy current measuring principle, providing a non-contact, wear-free measurement, and the measurement procedure is resistant to disturbances such as heat, dust and oil.
