Advanced ceramic green body precise machining method and advanced ceramic product manufacturing method

Abstract

The invention relates to an advanced ceramic green body precise machining method and an advanced ceramic product manufacturing method. The advanced ceramic green body precise machining method comprises the following steps: according to the product shape and size, calculating to determine the machined size requirement of a green body, and writing the program for carrying out finish machining on thegreen body; according to the product shape structure, selecting a tool clamp for finish machining of the green body, and positioning and clamping the green body on the tool clamp; adopting a numerically-controlled machine tool to carry out cutting on the green body; and controlling the rotating speed to be 2300-2700 rpm, the amount of feed to be 2.8-3.2 mm and the moving speed of a spindle to be1900-2300 mm / min. The advanced ceramic product manufacturing method comprises the following steps: mixing and pelleting; carrying out compression moulding on the green body; carrying out finish machining on the green body; sintering; and carrying out precise abrasive machining on a coarse ceramic product to prepare the advanced ceramic product. On the premise of keeping the product quality, the finish machining difficulty of advanced ceramics to a finished blank is lowered, the production cycle of the ceramic product is shortened and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of ceramic manufacturing and processing, and in particular relates to an advanced ceramic green body precision machining method and an advanced ceramic product manufacturing method. Background technique [0002] The existing production technology of advanced ceramic products usually only includes the four links of mixing, molding, sintering and finishing. However, advanced ceramic components used in major equipment in high-precision fields such as semiconductors and liquid crystal panels usually not only require high product purity, but also have extremely strict precision requirements, and cannot tolerate any microstructural flaws. These ceramic products are made of various high-purity advanced ceramic powders, and the general characteristics of these parts are: [0003] 1. The size is extremely large: discs and rings with a diameter of 500mm are very common; [0004] 2. Complex structure: many products h...

AI Technical Summary

Problems solved by technology

[0003] 1. The size is extremely large: discs and rings with a diameter of 500mm are very common;

[0004] 2. Complex structure: many products have complex structures with steps or inclinations;

It is precisely because of the above reasons that the difficulty of finishing the product is increased, and the processing cycle and processing cost of the product are greatly extended.
