Bonding and disc forming method for optical part machining process

Abstract

The invention discloses a bonding and disc forming method for the optical part machining process, and relates to the field of precise optical machining. The bonding and disc forming method comprises the following steps of bonding agent preparing, disc feeding bonding pad manufacturing and part disc feeding, specifically, a bonding agent used for bonding parts and a disc feeding plate is prepared,a disc feeding bonding pad is manufactured through the bonding agent, and the parts are bonded into a disc through the disc feeding bonding pad for a cushion plate. According to the bonding and disc forming method for the optical part machining process, the purpose that the aperture changing amount of the disc feeding and discharging part surface shape of a thin part (the ratio of the diameter tothe thickness is 10:1) is decreased to 0.1 from 0.5 is achieved; the parts can be put in the midway in the part machining process, the defect that continuous machining must be conducted is avoided, the adjusting space for the production schedule in the part machining link is increased, and the machining efficiency is improved; the defect that disc feeding can be conducted only after the surface ofthe part is polished and the surface cleanliness and roughness meet the high requirements is avoided, and the part machining range is widened; and operation is easy, and use is convenient.

Description

technical field [0001] The invention relates to the field of precision optical processing, in particular to a bonding method for forming discs in the processing of optical parts. Background technique [0002] It is the result of historical inheritance that planar optical parts need to be processed on the plate, mainly because the effective aperture of most flat plates and prisms is relatively small; and their shapes are rather peculiar, and there is a certain angle between the planes. From the perspective of improving production efficiency and quality, It is necessary to put the parts on the disk in a certain form and process the parts in a disk. [0003] After the popularization of high-speed machining technology for optical parts, due to the versatility of the plane, it does not have a specific radius of curvature like a spherical surface. Therefore, plane machining still maintains the characteristics of upper plate processing. In the main processes such as milling, fine ...
