微圆弧金刚石刀具修磨技术研究
Research on dressing and truing of microarc diamond tool
摘要
Abstract
The microarc diamond tool is widely applied in ultra-precision machining.Research on micro arc diamond cutter dressing technology is implemented based on mechanical grinding.Through the analysis of the preparation technology of microarc diamond tool and its difficulty, a new method to dress the microarc diamond tool is designed to solve technical nodi such as locating at both hard and easy directions, breakage of blade tips, and precision dressing of tip arc.Experiments show that a microarc diamond tool with tip radius of 8.2 μm is prepared, which is investigated using atomic force microscope and high-magnification optical microscope.It is found that the roughness of the rake face was 1.50 nm and the profile waviness of the tip better than 0.1 μm, which is slmiliar to imported high-precision tools.Actual application of ultra-precision cutting microstructure reveals that the tool has good machining effect.关键词
