AI Technical Summary
In existing technologies, ceramic-bonded superhard material grinding wheel forming materials have poor uniformity, insufficient fluidity, and low wet blank strength, resulting in uneven wear of the grinding surface and easy abrasive shedding, making it difficult to meet the needs of high-end manufacturing.
By employing a solid wetting agent formulation (polyethylene glycol stearate, hydrogenated castor oil, modified lanolin, nano silica, and polyepoxysuccinic acid PESA) and a hot mixing process, ceramic binders are uniformly coated onto the surface of superhard abrasives, thereby improving the looseness, flowability, and wet blank strength of the molded material.
It significantly improves the uniformity of the molding material and the strength of the wet blank, stabilizes the grinding performance, ensures uniform consumption of the grinding surface, reduces abrasive shedding and chip adhesion, and improves the machining accuracy and surface quality of the workpiece.
