Machining method for microcrystal glass wafers

Abstract

The invention belongs to the technical field of glass wafer machining, and in particular, discloses a machining method for microcrystal glass wafers, and aims to solve the problems of lower utilization rate of raw materials in traditional microcrystal glass wafer machining methods and incapability of effectively improving the defects generated in the slicing process. The machining method for the microcrystal glass wafers comprises a strip shaping step, a dicing step, a block shaping step and a trimming step, and further comprises a slicing step, a finish grinding step and a polishing step. Linear cutting equipment is adopted for cutting, and can directly cut blocks to flaky blanks with a thickness below 1 mm; the diameter of steel wires is only about 0.13 mm; cutting gaps generated by slicing are narrow; and generated destruction layers are shallow. Compared with the traditional machining methods, the machining method increases the material utilization rate by about 80%, reduces the edge breakage width of the flaky blanks from initial more than 3 mm to below 0.15 mm, and can effectively improves the defects generated in the slicing process through finish grinding and polishing of the flaky blanks.

Description

technical field

[0001] The invention belongs to the technical field of glass flake processing, and in particular relates to a method for processing a glass-ceramic flake. Background technique

[0002] Glass-ceramics refers to the basic glass of a specific composition. It is crystallized and heat-treated under a certain temperature system, and a large number of tiny crystals are uniformly precipitated in the glass to form a dense multi-phase composite of microcrystalline phase and glass phase. Glass-ceramics has both the structural characteristics and properties of glass and ceramics, also known as glass ceramics.

[0003] Most of the existing glass-ceramic blanks are in the form of strips. With the demand of the market, it is now necessary to process the glass-ceramic from the strip form into thin slices with a thickness of less than 1mm, so as to be used as blanks for subsequent finishing of certain products. At the same time, it is necessary to test the various properties...
