Finishing of Advanced Ceramic Materials

Finishing of Advanced Ceramic Materials

Finishing machining refers to a machining technique that achieves stable and even higher machining accuracy levels while significantly improving the surface quality of the processed object,

It is the final process of most parts. Its main functions include: reducing surface roughness of parts, removing surface defects such as scratches and micro cracks, and improving and improving

Surface quality of parts; Improve the physical and mechanical properties of the part surface, improve the stress distribution state of the part surface, and improve the service performance and lifespan of the part; Improving the surface of parts

Glossiness and brightness, improving the surface cleanliness of parts; Remove burrs, rounding, chamfers, etc. to ensure smooth transitions between surfaces and improve the assembly process of parts.

According to the historical evolution and different processing mechanisms used, finishing technology can be divided into the following two categories. One type is based on the principle of cutting processing

The pure mechanical finishing method, collectively known as traditional finishing technology, mainly includes mirror grinding, honing, ultra precision grinding, grinding, and polishing. another

One type is a combination of chemical or electrochemical dissolution processing, high-energy processing, and multiple processing principles for finishing, known as non-traditional finishing technology. Its content

Mainly including chemical photofinishing, electrochemical polishing, pulse electrochemical finishing, electrochemical mechanical finishing, and ultrasonic processing. This chapter mainly introduces grinding and honing

Finishing methods such as grinding and polishing.

Grinding processing usually refers to the use of micrometer sized abrasive particles with higher hardness than the material being processed, and the micro cutting and rolling effects generated under the action of a hard grinding disc to achieve addition

The removal of trace materials on the working surface enables the shape and dimensional accuracy of the workpiece to meet the required values, while reducing surface roughness and reducing the processing of metamorphic layers.
