What is the achievable machining accuracy for grinding ceramic structural parts?

The grinding accuracy of ceramic structural components depends on equipment performance, abrasive selection, process parameters, and the ceramic material itself. There is a significant difference in accuracy between conventional precision grinding and ultra-precision grinding. In conventional precision grinding, diamond grinding wheels are used in conjunction with high-rigidity machine tools, enabling dimensional tolerances to be controlled within **±1–5 μm**. Flatness/parallelism can reach 1–3 μm, cylindricity/circularity is 1–2 μm, and surface roughness (Ra) remains at 0.1–0.4 μm, meeting the precision requirements for most industrial wear-resistant parts and insulating supports. Ultra-precision grinding—such as ELID online electrolytic dressing technology—can achieve sub-micron-level accuracy, reducing dimensional tolerances to **±0.1–1 μm**. Flatness/circularity can be controlled within 0.1–0.5 μm, and surface roughness (Ra) can be as low as 0.01–0.05 μm, making it suitable for high-end components such as semiconductor substrates and precision bearings. To enhance accuracy, three key factors must be carefully managed: First, select diamond grinding wheels with a grit size of ≥200#, set the linear velocity at 15–30 m/s, and adjust the feed rate to 0.5–2 μm/pass; second, maintain a constant-temperature, vibration-isolated environment and use a laser interferometer for real-time monitoring; third, tailor process parameters according to different materials such as alumina and silicon carbide to prevent thermal deformation and brittle cracking.

What are the machining processes for ceramic structural components?

The manufacturing process for ceramic structural components must be carried out in stages, covering the entire workflow from raw materials to finished products. The core process can be broadly divided into two major categories: forming processes and post-processing techniques, as detailed below: Forming Processes (the Core Stage of Green Body Preparation) Dry Pressing: Ceramic powder mixed with a small amount of binder is placed into a mold and then pressed to form the green body. This method boasts simplicity, high efficiency, and low cost, making it suitable for medium- and small-sized parts with regular shapes (such as ceramic wear-resistant plates and insulating shims). However, it is difficult to produce parts with complex geometries using this technique. Slip Casting: A ceramic slurry is poured into a plaster mold, where the mold's water-absorbing properties cause the slurry to solidify into a green body. This method is ideal for thin-walled and complex-shaped parts (such as ceramic pipe fittings and custom brackets). However, the green bodies produced by slip casting have lower density, so the slurry concentration must be carefully controlled. Injection Molding: Ceramic powder is mixed with a thermoplastic binder, heated until melted, and then injected into a mold. This process enables the production of highly precise parts with intricate structures (such as miniature ceramic gears and electronic component bases), making it well-suited for mass production. However, the subsequent removal of the binder adds extra steps to the process. Isostatic Pressing: In a high-pressure vessel, uniform pressure is applied to the ceramic green body, resulting in a dense and uniformly compacted green body. This method is particularly suitable for parts requiring high performance and high density (such as ceramic cutting tools and high-temperature structural components). Nevertheless, the equipment required for this process is relatively expensive. Post-Processing Techniques (the Finishing Stage After Sintering) Grinding: Using diamond grinding wheels, sintered ceramic parts are ground to achieve fine finishing. This is the primary method for precision finishing of ceramics, improving dimensional accuracy and surface smoothness. It is widely used for precision seals, bearings, and other components that demand tight tolerances. Polishing: Through mechanical or chemical polishing, the surface roughness of ceramics is reduced to meet the surface requirements of optical components and precision parts. Drilling and Cutting: Diamond tools are used for drilling and cutting ceramic parts to achieve the desired hole positions and external dimensions. Care must be taken to control the feed rate to prevent brittle cracking due to the inherent fragility of ceramics.
