Method of laser-curing and forming honeycomb grinding block made from fine-grained diamonds and ceramic binding agent

A method of laser-curing and forming a honeycomb diamond grinding block made from fine-grained diamonds and a ceramic binding agent, the method comprising:

• an operation S1:
• preparing a slurry, wherein components of the slurry, by mass ratios, comprise 20-21 parts of photosensitive resin, 34.5-37 parts of aluminum-oxide powder, 4-5.5 parts of fine-grained diamond powder, and 0.04-0.1 parts of a photoinitiator;
• particle sizes of the fine-grained diamond powder range from 6-8 μm;
• particle sizes of the aluminum-oxide powder range from 1-8 μm;
• and the aluminum-oxide powder serves as the ceramic binding agent;
• an operation S2:
• stirring the slurry to allow all of the components in the slurry to be fully mixed with each other, until no air bubbles are generated, to obtain a printing material, wherein the printing material comprises the aluminum-oxide powder and the fine-grained diamond powder;
• an operation S3:
• feeding the printing material that comprises the aluminum-oxide powder and the fine-grained diamond powder into a laser-curing printer to perform laser-curing 3D printing to obtain a precursor of a finished product of the honeycomb diamond grinding block;
• and
• an operation S4:
• performing, by a high-temperature furnace, a degreasing operation and a high-temperature sintering treatment on the precursor of the finished product of the honeycomb diamond grinding block to obtain the finished product of the honeycomb diamond grinding block;
• wherein a temperature of the degreasing operation is not greater than 700° C., and a temperature of the high-temperature sintering treatment is not greater than 900° C.
