The subdivision multi tooth indexing table is composed of a multi tooth indexing table and a set of subdivision drum reading systems. It can achieve a maximum resolution of 0.1 "for angle reading on fixed reading sleeves and movable reading sleeves, and is suitable for measurement sites that require continuous reading. The programmable multi tooth indexing table is controlled by a computer-controlled stepper motor to lift and rotate the upper gear plate, allowing the operation of the multi tooth indexing table to be controlled by the program and achieve automatic testing.
