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. figure 1 1-second handwheel; 2-image screen; 3-locking handle; 4-coarse hand wheel; 5-work table; 6-zero hand wheel
