The invention relates to the technical field of cutting tools, in particular to a preparation process of self-lubricating ceramic material cutting tools, which is characterized in that the process steps are: (1) Nano-thulium zirconium ceramic powder prepared by hydrothermal precipitation method, its composition The content and mass percentage are: 7% to 38% of thulium oxide, 62% to 93% of zirconia, (2) after adding TiC composite, ball milling, (3) adding solid lubricant, the radius of the solid lubricant particle ceramic composite material The ratio is 0.225≤r/R≤0.419, (4) mixed after ball milling, (5) vacuum dried, (6) put into graphite mold, (7) prepared by hot pressing sintering process, and the sintering temperature is 1500°C-1700°C , holding time 40 minutes. Compared with the prior art, the present invention has a simple technological process, and the self-lubricating ceramic tool has the functions of anti-friction, anti-wear and lubrication, saves the cooling and lubrication system, reduces equipment investment, avoids environmental pollution caused by cutting fluid, and realizes clean production. reduce manufacturing cost.
