This paper discusses some problems about nanometer lapping photonics elements. The solid abrasives high speed lapping method and the theory of lapping tool wearing uniformly are used in machining photonics elements. It makes workpiece machined surface roughness reach to Ra0.88nm, flatness reach 19nm. That not only realizes nanometer machining, but also realizes machining at high efficiency and low cost.
