Getting accuracy out of machine tools: Linear encoders eliminate errors from thermal drift
Linear encoders help eliminate errors from thermal drift. || Dr. Jens Kummetz, R&D Manager, HEIDENHAIN, Traunreut, Germany Thermal accuracy of machine tools is becoming increasingly important considering the strongly varying operating conditions in manufacturing. Especially with small production batches that require constantly changing machining tasks, a thermally stable condition can’t be reached. At the same time, […]
The Next Step in Non-contact Sensing
by Eric Mueller, Sensor Magnets Product Manager, Dexter Magnetic Technologies, Elk Grove Village, Ill. Non-contact linear and rotary position measurement is attainable with robust multi-pole magnets Today’s machinery and motion systems have an increased need for accurate, repeatable and reliable measurement of linear and rotary position. The evolving history of position sensing ranges from simple electromechanical […]
