Extensive use of micro-parts requires higher precision and surface quality, and processing defects including poor surface roughness and micro burrs in micro-processing must be further removed to improve surface processing quality. There-fore, quality of micro-machined surface has aroused more attention of scholars both at home and abroad, and has become a focus and hotspot of domestic research. Research findings and research status concerning surface quality in micro-machining were re-viewed, classified and summarized. Firstly, background and significance of micro-machining were introduced, characteristics of micro-cutting were reviewed and the surface quality was discussed in respect of surface roughness, surface residual stress, sur-face hardening and micro burrs. Then the processing technology was expounded in terms of fine turning, fine milling, fine mil-ling and micro grinding. Test methods and scientific research results concerning surface quality in micro-cutting process were summarized. Relevant factors affecting surface quality, including cutting elements, tool elements and other cofactors, and law of processing affecting surface quality was concluded. Finally, quality of micro-machined surface was summed up, and some ways, methods and suggestions of improving quality of machined surface were proposed.
