0.1µm Glass Scale Optical Linear Encoders for Lathe Machine
The EA series has a 7 inch color LCD screen which provide inactive graphic display and step by step operation graphical guidance for all DRO functions, which makes EA-926 extremely user friendly, allow operators can implement all the powerful DRO function within few minutes after switch on the DRO.
Purpose: It is matched with various sensors for measuring on machine tools and displaying the measured results in digital form.
