[0031] 1) On the lower grinding disc 5 of the double-sided grinding and polishing machine, install the intermeshing inner gear ring 1, the external gear sun gear 4 and five planetary discs 2 with external teeth. hole 3.

[0032] 3) Put 25 pieces of crystal material 7 in the through hole 3, and the crystal material 7 is adapted to the size of the through hole.

[0033] 3) Place a buffer pad 9, a fixed layer 10, and a pressure block 11 on each planetary disc 5 in sequence, and the pressure of the pressure block is 300g / cm 2 .

[0034] 4) The upper grinding disc is always kept out of contact with the lower grinding disc for polishing.

[0035] 5) Polishing conditions: the speed of the lower grinding disc: 16~60rpm, and the ratio of the external gear sun gear to the lower grinding disc is 1:3~1:10.

[0036] In this embodiment, only the lower grinding disc polishes the crystalline material, which realizes single-sided polishing on a double-sided polishing machine.

Abstract

The invention discloses two single-side polishing methods realized on a double-side lapping machine, including a weight type single-side polishing method of the double-side lapping machine and a pasting type single-side polishing method of the double-side lapping machine. The weighted single-side polishing method of the double-side polishing machine mainly includes: setting a pressing block on the planetary plate, and polishing the upper grinding plate without contacting the lower grinding plate. The paste-type single-sided polishing method of the double-sided polishing machine mainly includes: bonding the surfaces of the crystal material that do not need to be polished together with an adhesive, and polishing the upper and lower grinding discs at the same time. By using the above two methods on the double-sided polishing machine, the crystal material can be polished on one side on the double-sided polishing machine, without the need to purchase a special single-sided polishing machine, which can fully save costs and further improve processing efficiency. conducive to industrialization.

Description

technical field [0001] The invention relates to two polishing methods realized on double-sided lapping and polishing machines, in particular to two single-sided polishing methods realized on double-sided lapping and polishing machines. Background technique [0002] At present, with the development of modern high technology, crystal materials are more and more widely used in electronics, optics, instrumentation, aerospace and civil industries. Crystal grinding and polishing machines are mainly used for the processing of crystal materials, but in the prior art, the same grinding and polishing machine does not have the function of single-side polishing and double-side polishing at the same time, that is, the double-side polishing machine does not have the function of single-side polishing. Therefore, in practical applications, when both single-sided polishing and double-sided polishing are required, it is necessary to purchase a single-sided crystal polishing machine and a doub...
