[0032] 1) On the lower grinding disc 5 of the double-sided polishing machine, install the intermeshing inner ring gear 1, the external tooth sun gear 4 and five planetary discs 2 with external teeth. Each planetary disc 2 has five channels. Hole 3.

[0033] 3) Put 25 pieces of crystal material 7 in the through hole 3, the crystal material 7 is suitable for the size of the through hole.

[0034] 3) Put a buffer pad 9, a fixed layer 10, and a briquetting block 11 on each planetary disc 5 in sequence, and the pressure of the briquetting block is 300g / cm 2 .

[0035] 4) Keep the upper grinding disc out of contact with the lower grinding disc for polishing.

[0036] 5) Polishing conditions: the rotational speed of the lower grinding disc: 16~60rpm, the rotational speed ratio of the external gear sun gear and the lower grinding disc is 1:3~1:10.

[0037] In this embodiment, only the lower grinding disc is used to polish the crystal material, realizing single-sided polishing on a ...

Abstract

The invention discloses two methods of achieving single-side polishing on a double-side polishing machine. The two methods include a pressure type single-side polishing method of the double-side polishing machine and an adhesion type single-side polishing method of the double-side polishing machine. The pressure type single-side polishing method of the double-side polishing machine mainly includes: arranging pressing blocks on planetary plates, wherein an upper grinding plate and a lower grinding plate are always in a non-contact state, and carrying out polishing. The adhesion type single-side polishing method of the double-side polishing machine mainly includes: adhering surfaces of crystal materials together, wherein the surfaces are needless to be polished, and meanwhile carrying out the polishing on the upper grinding plate and the lower grinding plate. By means of the two methods, the single-side polishing of the crystal materials can be achieved on the double-side polishing machine, a special single-side polishing machine is needless to be purchased, cost is fully saved, and machining efficiency is further improved and industrialization is facilitated.

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...
