Spherical optical lens milling and grinding device and machining process thereof

The invention relates to a milling and grinding device for a spherical optical lens, which belongs to the technical field of optical lens processing, and comprises a workbench, a first motor is arranged in the workbench, the first motor is connected with a turntable, and at least one group of clamping seats symmetrical about the circle center of the turntable are slidably arranged on the turntable; the rotating disc is provided with an adjusting piece used for driving the clamping seats in the same group to relatively move towards the circle center of the rotating disc at the same time, clamping grooves are formed in the opposite sides of the two clamping seats in the same group, and when the circular spherical optical lens is tangent to the two side faces of all the clamping grooves at the same time, the circular spherical optical lens is concentric with the rotating disc; positioning blocks are arranged on the clamping seats, one lines of the two positioning blocks in the same set coincide and pass through
