Measuring the thermal extension in spindles

 

The displacement measurement system SGS 4701 (Spindle Growth System) has been developed for high speed milling machine applications. Due to high machining speeds and the heat generated, the linear thermal extension of the precision machine tool spindle 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 extension of the spindle. The measurement takes places typically on the labyrinth-ring. As well as measuring linear thermal extension, the temperature of the sensor is also detected and output.These measurement values are fed into the CNC machine tool as correction values, compensating for any positioning errors.

Compact Structure

The SGS 4701 consists of a sensor, a sensor cable and a controller, factory calibrated for ferromagnetic and non-ferromagnetic measurement objects. Two miniature sensors enable it to be installed directly in the spindle. The compact controller can be installed on the spindle housing via a flange or directly in the spindle.
 

Robust design

The SGS 4701 operates on the eddy current measuring principle. This non-contact measurement is wear-free. Furthermore, the measurement procedure is resistant to disturbances such as heat, dust and oil.

MDS-SensorMagneto-inductive displacement sensors

OEM sensors according to the inductive magnetic principle can be adapted to customer requirements very quickly and easily. Measuring ranges up to 60 mm are currently possible. The sensor can vary in shape, size and type of output. Only a small magnet has to be attached as target to the measurement object. MDS sensors provide a very high resolution and measure particularly fast movements. The MDS is available as a pure circuit board version or also in a plastic case.

clampCONTROL: Clamping stroke monitoring

 
 

clampCONTROL is used on machine tools for monitoring the automatic tool holder. Thereby, the sensor checks whether a tool is inserted, not inserted correctly or not inserted at all. Even if a chip is located in the tool holder, this will be measured by clampCONTROL.

Details

Compact, integrated sensor
High resolution
Shaft and sensor in one axis
No extension of the overall installation length due to the sensor
