Abstract：To improve the grinding qualityof nickel based superalloy honeycomb，a comparative studywasconductedon theinfluenceof grinding parameters and whel structure onburrsize under conventional grinding and ultrasonic assisted grinding.The research results show that compared with ordinary grinding，ultrasonic asisted grinding can ffectively reduce the burr sizeof nickel-based superally honeycomb，especiallyfor welding edges.Compared to white corundum grinding wheel，employing ceramic bond CBN grinding wheelscan achievesmaler burr size. Through grinding experiments，optimized process parameter is obtained.
