Embodiment Construction

[0019] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0020] A method for forming and processing loose ceramic parts, the processing method comprising the following steps:

[0021] Step 1: Design the tooling base used to support the parts, and its flatness and parallelism are required to be within 0.01mm and 0.05mm respectively, such as figure 1 shown;

[0022] Step 2: Place the tooling base on the heating plate, and when the temperature of the tooling base reaches above 50°C, apply paraffin evenly on the assembly surface of the tooling base;

[0023] Step 3: If figure 2 As shown, place the loose ceramic body on the assembly surface of the tooling base, and take it off after cooling to room temperature;

[0024] Step 4: Use the mechanically processed combination fixture to complete the clamping of the bonded parts and perform mechanical processing;

[0025] Set the spindle speed (N), feed (f) and cutting amount...

Abstract

The invention relates to a molding and machining method of loose ceramic parts. Through the tool design, stable machining is realized by matching and using the paraffin loose ceramic part, a high precision numerical control machine tool is used for improving the machining efficiency and surface quality of the parts, and the problem that the loose parts are prone to edge collapsing, cracking and other machining defects in the molding and machining. The molding and machining method of the loose ceramic part has the beneficial effects that a method of wax bonding is adopted to connect the parts with tools, non-stress clamping of the parts is realized through the clamping tools, the molding and machining of complicated loose ceramic materials with different configurations are met, and the lightweight requirements of the products are met; and compared with conventional cutting, high speed machining has the advantages of high cutting efficiency, high cutting precision, small cutting force and low machining costs, and the high efficiency and high quality machining of the loose ceramic materials is ensured.

Description

technical field [0001] The mechanical processing and manufacturing method of the invention relates to a molding and processing method of loose ceramic parts. Background technique [0002] Ceramic materials have excellent physical properties, chemical properties and mechanical properties, and are widely used in aerospace and aviation fields. Taking SiC as an example, as a new type of wide-bandgap semiconductor material, it has many excellent physical and chemical properties, high thermal conductivity and low thermal expansion coefficient make SiC a good choice for making optical components and mechanical parts with good thermal deformation resistance. One of the best materials, and also one of the best optical mirror materials at present, will play an important role in improving the quality of future optical products. [0003] In order to meet the requirements of use, ceramic materials need to be sintered at high temperatures, and at high temperatures, the solid particles of...
