Abstract

A high-precision turning device. The device has a base plate, a base, a support A, wherein a groove is formed in the center of the bottom surface of the base, and a lead screw passes through the groove; symmetrical T-shaped annular grooves are formed in two sides of the interior of the base, two symmetrical T-shaped annular columns are arranged on the lower end face of a turning block, and the T-shaped annular columns can be inserted into the T-shaped annular grooves; and the structure of a central position of the lower end face of the turning block is annular teeth, and the annular teeth are meshed with the lead screw. A servomotor drives the lead screw to rotate, and by virtue of meshing matching of the annular teeth and the lead screw, the turning block can turn along the centers of the T-shaped annular grooves in the base.
