Metal ceramic composite binding agent grinding wheel for powerful slotting of tungsten steel milling cutter and preparation method of metal ceramic composite binding agent grinding wheel

The invention discloses a metal ceramic composite binding agent grinding wheel for powerful grooving of a tungsten steel milling cutter and a preparation method. The metal ceramic composite binding agent grinding wheel comprises the following raw materials of, by mass, 10-30 parts of a low-temperature ceramic binding agent, 40-60 parts of copper-tin alloy powder, 2-10 parts of spherical graphite powder and 10-30 parts of diamond powder. Wherein the low-temperature ceramic bond comprises the following raw materials in parts by mass: 30-50 parts of silicon dioxide, 5-10 parts of aluminum oxide, 15-25 parts of boric acid, 5-15 parts of lithium carbonate, 2-10 parts of zinc oxide, 2-10 parts of titanium dioxide and 2-10 parts of zirconium dioxide; the low-temperature ceramic bond is prepared by adopting a specific formula, and the copper-tin alloy powder, the spherical graphite powder and the diamond powder in a specific proportion are added in a matched manner, so that the wear resistance of the prepared metal c
