3 Overview
Optical and digital indexing table is a precision angle measurement based on an optical dial or a circular grating or an angle encoder.
Instrument for angle and circle indexing. The tilt angle of the tiltable table is 0°~90°.
The outline of the optical indexing table is shown in Figure 1.
