Magnetic versus Optical

A comparison of angular measuring systems for rotary axes

For rotary tables used for milling and turning operations, a wide range of high performance drive components is available. In particular, this covers torque motors and the associated converters and controllers as well as rotary table bearing arrangements matched to these. When selecting the angular measuring system for highly dynamic, direct drive rotary table axes intended for use in combined milling and turning, optical measuring systems with very high accuracy and angular resolution are generally given preference. Due to the optical measurement principle, however, no special precautions are taken in relation to contamination by, for example, cooling lubricants or rolling bearing greases.
