Embodiment 1

[0027] see Figure 2 to Figure 4 , The annular surface of the copper disc 1 in the figure is provided with a spiral grinding groove 11, and a stepped groove 12 is provided along the annular outer ring and the inner ring of the copper disc 1. In addition, the grinding groove 11 can also be arranged in the form of concentric circles, and both can be processed by turning. Wherein the depth of the grinding groove 11 is: 0.25-0.35mm, and the spacing of the grinding groove is: 1.2-1.4mm (attached figure 2 The spiral shape is highlighted in the middle, which is only a schematic diagram and does not represent a specific size requirement).

[0028] specific combination figure 1 For the positional relationship of the middle star wheel, the width of the step groove 12 should not be less than the minimum distance from the edge of the star wheel cavity placed on the copper plate 1 to the outer edge of the copper plate, so as to ensure that all the grinding groove areas on the copper pla...

Embodiment 2

[0031] Copper dish 1 among the embodiment 1 is applied in Figure 5 The shown double-sided copper disc polishing machine includes an upper copper disc 1' and a lower copper disc 1 that rotate in opposite directions. The upper copper disc 1' is set on the lower copper disc 1 through a lifting arm 8, and the upper copper disc 1' On the boom 8 on one side, a lower turning tool 7 facing downward is fixed, and on the opposite side of the lower copper plate 1, an upper turning tool 9 is fixed; specifically, the lower copper plate 1 and the upper turning tool 9 A mounting seat is arranged on the transverse guide rail 6 on the double-sided copper disc polishing machine, and the lower copper disc 1 and the upper disc turning tool 9 are moved and fed along the transverse guide rail 6 through motor drive, wherein the upper disc turning tool 9 and the lower disc turning tool 9 Turning knife 7 is arranged laterally along the guide rail direction, and the distance from lower turning knife 7...

Abstract

The invention discloses a copper disc for sapphire polishing. Grinding grooves in a spiral or concentric circle shape are formed in an annular surface of the copper disc, and stepped grooves are formed in an annular outer ring and an inner ring of the copper disc. The invention further discloses a disc repair method of the copper disc for sapphire polishing. The disc repair method specifically includes the following steps that firstly, an upper copper disc and a lower disc turning tool or a lower copper disc and an upper disc turning tool are horizontally moved, and the turning tools are aligned to the original positions of the grinding grooves in the corresponding copper discs; secondly, the upper copper disc and the lower copper disc are controlled to rotate at the same rotation speed in the opposite directions, the turning tools are fixed and not moved, the upper copper disc or the lower copper disc is controlled for transverse feed, and corresponding grinding grooves are turned through the turning tools; thirdly, the turning tools are moved away, and the surfaces of the corresponding copper discs are flushed. According to the copper disc, the surfaces of the copper discs can be evenly abraded, and machining quality of sapphire panels is guaranteed. According to the disc repair method, the grinding grooves in the copper discs can be quickly finished, and production efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of sapphire processing, and in particular relates to a copper disk for sapphire polishing and a method for repairing the disk. Background technique [0002] Due to its good physical and chemical properties and light transmittance, sapphire is widely used in screens or protective panels of mobile phones, computers, watches, etc., but because such applications require good flatness, the flatness requirements for sapphire panels very high. Usually this type of process requires a grinding disc, which is then polished with a grinding liquid. [0003] The current polishing disks are metal disks, alloy disks or composite material disks. Rough grinding grooves are set on the disks. The grinding grooves on the disks cooperate with the abrasive liquid to grind and polish sapphire. The copper disk is used for sapphire. The best polishing disc for polishing, such as the Chinese utility model patent synthetic copper disc grindin...
