Treatment method for improving surface performance of alumina-based ceramic cutter

A treatment method for improving the surface performance of an aluminum oxide-based ceramic cutter comprises the following process steps that firstly, the aluminum oxide-based ceramic cutter is selected, and an acetone solution is adopted for ultrasonic cleaning for 30 min to remove oil stains and other impurities on the surface of the cutter; then the treated cutter is placed in an automatic liquid sand blasting machine, it is guaranteed that the cutter to be treated is located in the center of a clamp, abrasive materials of a sand blasting device are ZrO2 or Al2O3 particles, and a mixture of the abrasive materials and water is pushed by high-pressure gas to impact the surface of the cutter; and finally, the treated cutter is subjected to ultrasonic cleaning with an acetone solution for 10 min, residual abrasive particles and other impurities on the surface are removed, and the tool is obtained. The alumina-based ceramic tool is subjected to surface treatment by using a micro sand blasting treatment process,
