Abstract

The invention discloses a sapphire window grinding and polishing device and a clamping jig thereof. The clamping jig of the sapphire window grinding and polishing device comprises a chuck, a marble flat plate, a flexible buffering cushion and a clamping ring which are sequentially arranged from top to bottom, and the clamping ring comprises a bottom plate and a side plate arranged around the side face of the bottom plate; and a clamping groove matched with the sapphire window in shape is formed in the bottom plate so that the sapphire window can be sleeved with the clamping groove to achieve grinding and polishing clamping machining, the marble flat plate and the side plate of the clamping ring are detachably connected through a fastener, the flexible buffering cushion is located between the bottom plate and the marble flat plate, and an iron pen holder is mounted on the chuck. The clamping jig of the sapphire window grinding and polishing device is easy to operate and high in universality.

Description

technical field [0001] The invention relates to the technical field of lapping and polishing devices, in particular to a lapping and polishing device for a sapphire window and a clamping fixture thereof. Background technique [0002] With the continuous development of science and technology, the requirements for window materials with photoelectric properties and other functions are gradually increasing. The performance of optical glass windows in the traditional sense can no longer meet the existing practical application standards. The characteristics of single crystal sapphire determine that it can be widely used as an optical window in defense technologies such as submarines, missiles, satellite space technology, and military infrared devices. [0003] Due to the characteristics of high hardness, high brittleness and stable chemical properties of sapphire crystal, it is difficult to grind and polish the sapphire crystal, and the processing time is long. In addition, the s...
