Ceramic parts precision processing process:
1. Mixing of raw materials: Mix the powders of various components evenly in a ball mill.
2. Granulation: Add a certain molding agent to extremely fine powder to make particles of similar size and good fluidity (about 80 microns). After granulation, it is helpful to improve the mold filling property and increase the mold filling density.
3. Forming: The hydrostatic forming method uses the incompressibility of the liquid medium and the uniform pressure transmission to press the powder into a high-density green body, which is a precision ceramic part. prototype.
4. One-time processing: Process the hydrostatic green body before sintering ceramic parts.
5. Sintering: The green body is sintered at high temperature. Under high temperature conditions, the surface area of the green body is reduced. The porosity is reduced, the mechanical properties are improved, and high densification is achieved, completing the sintering molding of ceramic parts.
6. Secondary processing: Use diamond tools to perform secondary processing on highly densified sintered bodies. The hardness of highly densified sintered bodies is close to diamond, and the processing time is longer.
7. Inspection: Test the processed products (size, flatness, surface smoothness, etc.). Visual inspection (nicks, cracks, etc.).
8. Cleaning, packaging, and shipping: Clean the products that pass the test. The cleaned products are packaged in the dust-free workshop and sent to the destination.
