Abstract

The invention discloses a grinding device, which comprises at least two grinding wheels, the mesh numbers of the at least two grinding wheels are different, and the mesh number refers to the number of grinding particles per unit area on the surface of the grinding wheel; the mesh numbers are different The at least two grinding wheels are used to grind the object to be ground in order of mesh number from small to large; wherein, the grinding wheel includes a grinding groove for accommodating and grinding the object to be ground; the grinding groove is arranged at On the outer peripheral surface of the grinding wheel, and in the plane where the axis of the grinding wheel is located, the cross-sectional shape of the grinding groove is an isosceles trapezoid, and the opening angle of the grinding groove is 30°-60°. The invention also discloses a grinding wheel and a grinding method. The grinding wheel, grinding device and grinding method proposed by the invention can achieve better grinding effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a grinding wheel, a grinding device and a grinding method. Background technique [0002] With the development of display technology, large-size display screens have become relatively common display products. When making a large-size display, it is necessary to prepare a large-size glass substrate. Among them, for the cutting of large-size glass substrates, the grinding process of the cutting edge is an indispensable step in the panel production process. However, grinding the cutting edge of a large-sized glass substrate is likely to cause fragments, which will result in an area of ​​uneven thermal stress on the glass substrate. Contents of the invention [0003] In view of this, one of the objectives of the embodiments of the present invention is to provide a grinding wheel, a grinding device and a grinding method, which can achieve a better grinding effect. [0004] Based ...
