Heidenhain Grid encoder to test CNC machines

The KGM 281 grid encoder is available with a measuring range of Ø 140 mm and an increased accuracy of ±1 µm. The encoder’s grid plate with phase grating has an optical measuring standard. It is embedded in a two-piece aluminum holder, the design of which prevents mechanical stress from being induced at the level of the measuring standard even if the mounting surface is not plane. This makes it possible to guarantee the accuracy grade of ±1 µm for the system. The grid encoder tests the contouring accuracy of CNC machine tools dynamically.
