Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] As shown in the figure, a special grinding wheel for liquid crystal glass includes a diamond edging wheel 1, the outer peripheral surface of the diamond edging wheel 1 is provided with a plurality of concave arc-shaped grinding grooves 2, and the groove wall of the grinding groove 2 is provided with There is a copper coating 3, the thickness of which is 25 μm, and a concave arc-shaped groove 4 is provided on the groove wall of the grinding groove 2.

[0015] During processing, firstly, design the groove shape, use a CNC lathe to carve out the corresponding groove shape on the tool electrode according to the design, and use a copper disc as the tool electrode to improve the conductivity and reduce the intermediate links of processing, thereby reducing the deformation of the groove shape ;Secondly, use the CNC EDM to process the special edging wheel for liquid cry...

Abstract

The invention discloses a special grinding wheel for liquid crystal glass. The special grinding wheel comprises a diamond edge grinding wheel, wherein the peripheral surface of the diamond edge grinding wheel is provided with multiple concave arc-shaped grinding slots, and the walls of the grinding slots are provided with red copper coatings. Since the walls of the grinding slots are provided with the red copper coatings, the conductibility is improved, processing interlinks are reduced, and the slot type deformation is reduced.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a special grinding wheel for liquid crystal glass. Background technique [0002] At present, the survival of domestic liquid crystal glass is strongly supported by the state. In products below the 6.5th generation, the monopoly of foreign companies has been broken and major breakthroughs have been made. Use a special grinding wheel to grind the glass into a smooth arc edge to eliminate stress. [0003] The special grinding wheel in the prior art includes a grinding wheel body. The grinding wheel body is a diamond grinding wheel. The outer peripheral surface of the grinding wheel body is provided with a plurality of concave arc-shaped grinding grooves. The special grinding wheel with this structure is easy to accumulate chips during grinding. The liquid crystal glass cannot be used due to chipping and bright edges, which seriously affects the yield of the product. Contents of the invention ...
