MANUFACTURING METHOD OF DIAMOND POROUS GRINDING BLOCK BASED ON 3D PRINTING AND APPLICATION THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240024952 titled 'MANUFACTURING METHOD OF DIAMOND POROUS GRINDING BLOCK BASED ON 3D PRINTING AND APPLICATION THEREOF
Simplified Explanation
The patent application describes a manufacturing method for a diamond porous grinding block using 3D printing technology. The method involves designing a 3D printing model of a grinding block unit cell with adjustable porosity based on the internal cooling space required for abrasive debris in the grinding process. The model is imported into a software called Magics, where a frame of the 3D printing model of the diamond porous grinding block is filled with multiple 3D printing models of grinding block unit cells. A mixed powder of diamond abrasive particles and an aluminum alloy binder is prepared as printing powder. The 3D printing process, using selective laser melting (SLM) technology, is then performed to obtain the diamond porous grinding block. This grinding block is specifically designed to form a diamond structure grinding disc for grinding semiconductor substrates.
