The present invention relates to a near-shaping method for a monolithic ceramic milling cutter. The specific steps are: put the ceramic powder into the near-formed mold, and pre-press the mold; hot-press and sinter the pre-pressed near-formed mold to obtain a near-formed bar blank; perform surface fine grinding on the obtained near-formed bar blank Get a ceramic milling cutter. It is possible to realize the forming of multiple ceramic milling cutter bar blanks in one sintering process, which significantly improves the sintering efficiency for the large-scale production of milling cutters, thus promoting the mass production of ceramic milling cutters. The milling cutter made of near-formed bar blank has less surface damage, good performance, good stability, high dimensional accuracy and high surface finish, thus increasing the service life of the tool and effectively reducing the tool cost in cutting. |
