Abstract

The invention provides a three-dimensional (3D) glass machining method and a cutting tool of a numerical control machine, and belongs to the technical field of machinery. According to the method and the tool, the problems of frangibility and low yield of glass in an existing 3D glass machining method are solved. The 3D glass machining method comprises the following steps of: pretreatment: knowing a margin between a 3D glass blank 8 and a 3D glass finished product; cutting: if the margin is greater than a set margin, performing rough cutting until the margin is smaller than the set margin, and performing fine cutting until the 3D glass finished product meets a product design requirement; if the margin is smaller than the set margin, directly performing fine cutting until the 3D glass finished product meets the product design requirement. The cutting tool of the numerical control machine comprises a cylindrical body, wherein an annular concave shoulder is arranged at one end of the body; the surface of the annular concave shoulder is a tool machining surface; a part matched with the target shape of a product is arranged on the surface of the annular concave shoulder; carborundum is coated on the surface of one end of the body. 3D glass processed by using the 3D glass machining method has the advantages of high yield and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to glass processing, in particular to a 3D glass processing method. [0002] The invention belongs to the technical field of machinery and relates to glass processing, in particular to a CNC machine tool cutting tool for 3D glass processing. Background technique [0003] With the development of society, the amount of electronic products is increasing; such as mobile phones, cameras, mp3, mp4, e-books and tablet computers and so on. Previously, the display screens of electronic products were flat. [0004] With the advancement of science and technology and aesthetic requirements, some people have gradually proposed special-shaped glass display screens. There are many documents about it, such as a manufacturing method of a special-shaped glass as a shell [application number: 200810071346.5, publication number CN101321443A] as recorded in Chinese patent documents, including A. Using g...
