以单点金刚石车削和超精密金刚石磨削为基础的超精密加工能够经济地制造光学、机械和电子部件，或生产在微米和毫微米范围内的成形精度和表面粗糙度的产品。辅助成形精度和表面粗糙度测量技术在评估超精密加工表面质量中也起着重要作用。在香港建立了超精密加工中心，用各种设 Ultra-precision machining based on single-point diamond turning and ultra-precision diamond grinding enables the economical manufacture of optical, mechanical and electronic components, or the production of precision and surface roughness in the micrometer and nanometer range. Auxiliary forming accuracy and surface roughness measurement techniques also play an important role in evaluating the surface quality of ultra-precision machined surfaces. In Hong Kong established an ultra-precision machining center, with a variety of settings
