Diamond accurate grinding sheet and machining technology thereof

The invention relates to the technical field of novel machining and application of high polymer materials, in particular to a machining technology of a diamond accurate grinding sheet. The machining technology comprises the following preparation steps that S1, cold press molding is conducted, wherein a binding agent is put into a mold, and compression molding preparing is carried out; and S2, sintering is conducted, wherein the accurate grinding sheet is placed in a sintering machine to be sintered, and the accurate grinding sheet is prepared; According to the diamond accurate grinding sheet prepared through the technology, the accurate grinding sheet which is high in grinding speed, high in stability, excellent in performance and relatively good in high-temperature resistance can be prepared from pressing of raw materials to subsequent sintering; before sintering, nitrogen is introduced into the sintering machine so that the internal stability can be enhanced, and the safety in the sintering process is impro
