Binary vibration grinding machine and ternary vibration grinding machine compared to less three-dimensional vibration function; when the workpiece, forming grinding block, chemical grinding and water according to a certain percentage into the light machine container. Then start the vibration motor. The upper and lower ends of the vibrating motor shaft are provided with eccentric blocks, and their projections on the horizontal plane are at right angles. When the vibrating motor rotates at high speed, the two eccentric blocks produce an exciting force (centrifugal force) that varies in the horizontal direction in the horizontal plane, , So that the body produces a circular motion within the plane, while the excitation force does not pass through the body of the center of mass. So that the excitation moment (ie, the dumping torque) causes the container to swing around the horizontal axis. Since the bottom of the container is in the form of a ring, the amplitudes of the points do not coincide, so that the forming blocks and the workpiece in the container are both the vertical center axis The center of the ring roll, the synthetic movement of the circular spiral movement, while the container has a spiral angle, forming the grinding block and the workpiece along the spiral surface to slide up, so that the workpiece and the molding block in the movement increased friction, improve the light efficiency.
