[0023] Example 1
[0024] A preparation method of a metal-based ceramic grinding wheel for grinding stainless steel and titanium alloy, comprising the following steps:
[0025] (1) Composition of raw materials: 70% of zirconium corundum abrasive and 30% of binder in mass percentage; the composition of binder is: clay powder 30%, feldspar powder 30%, boron glass powder 40%;
[0026] (2) Mixing of raw materials: a. The abrasive described in step (1) is uniformly wetted with 12%wt sodium silicate solution to obtain mixture A; b. under stirring, add mixture A into the countercurrent mixer; c. stirring Next, add the binding agent described in step (1) to mixture A, and stop stirring after stirring for 30 minutes to obtain mixture B; d. Pass mixture B through a 24# screen;
[0027] (3) Forming stage: The sieved mixture B is assembled, formed, and demolded to obtain a green body grinding wheel. The isostatic pressing process is used for forming, and the pressure is 20MPa;

Example Embodiment
[0031] Example 2
[0032] The same parts of this example and Example 1 will not be repeated, the difference lies in the composition of the raw materials in step (1): by mass percentage, zirconium corundum abrasive 60%, binder 40%; the composition of the binder is: clay Powder 35%, feldspar powder 20%, boron glass powder 45%.
Example Embodiment
[0033] Example 3
[0034] The same part of this example and Example 1 will not be repeated, the difference is the composition of the raw materials in step (1): by mass percentage, zirconium corundum abrasive 85%, binder 15%; the composition of the binder is: clay 25% powder, 15% feldspar powder, 60% boron glass powder.
