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 disk for sapphire polishing. The annular surface of the copper disk is provided with spiral or concentric grinding grooves, and steps are provided along the annular outer ring and the inner ring of the copper disk. groove. The invention also discloses a method for repairing the above-mentioned copper disk for sapphire polishing. The specific disk repair steps are as follows: the first step, move the upper copper disk and the lower disk turning tool horizontally and laterally or the lower copper disk and the upper disk turning tool, and turn the turning tool The knife is aligned with the origin of the grinding groove on the corresponding copper plate. The second step is to control the upper copper plate and the lower copper plate to rotate in the opposite direction at the same speed. The turning tool is fixed, and the upper copper plate or the lower copper plate is controlled. Lateral feed, the corresponding grinding groove is turned by the turning tool, and the third step is to remove the turning tool and rinse the corresponding copper disk surface. The invention can realize uniform wear on the surface of the copper disc, ensuring the processing quality of the sapphire panel. The disc repairing method provided by the invention can quickly repair the grinding groove on the copper disc, effectively improving the production efficiency.

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...
