The invention belongs to the technical field of optical part preparation, and particularly discloses a device and a method for simultaneously
processing multiple planar optical parts.The device comprises a
polishing machine, a base die and a bonding die, the base die and the bonding die are connected to the
polishing machine, a fixing column is arranged on the edge of the base die, and a positioning area of the bonding die is determined on the base die; and the manufactured parts containing the adhesives are evenly distributed on the base die in the positioning area, the distance between the parts ranges from 1 mm to 2 mm, the bonding die is heated to 100 DEG C,
hot pressing is conducted on the parts through positioning of fixing columns, and when the temperature of the bonding die is reduced to 70 DEG C, 100 g of pressure per
square millimeter of the parts is applied till the parts are cooled and machined at the normal temperature. The device realizes simultaneous
machining of multiple planar parts, higher surface precision and parallelism can be easily obtained, according to the size of the mirror disc of a
polishing machine, compared with single optical part
machining, the
machining efficiency is improved by 5-30 times, and machining of ultra-small-
diameter parts is simplified.
