Abrasive grinding can effectively prevent surface damage caused by the process of large particles, and simultaneously improve processing efficiency and accuracy

Efficient, high-precision , low surface damage has always been ultra-precision machining pursuit of the goal . With the development of modern industry, for ultra-precision  synthetic diamond  are increasingly high requirements , reduce surface damage and processing to improve the processing efficiency of the contradiction between the increasingly prominent. To alleviate this problem, the research center proposed a fixed abrasive machining and free abrasive machining of semi- solid integration with grit abrasive machining technology, the core of which is the use of having a "trap " effect of semi- fixed abrasive grinding with ultra- precision machining. The abrasive surface can effectively prevent damage to the grinding process caused by large particles , simultaneously improve processing efficiency and accuracy. References of conventional abrasive manufacturing process ,  synthetic diamond powder  the characteristics of semi- fixed abrasive grinding tools , grinding tools for semi- fixed abrasive manufacturing process has been improved, made ​​more perfect machining process. By combining experimental study and additives , determining suitable for semi- solid formulations with abrasive grit . Referring to the traditional abrasive characteristic parameter detection method chosen hardness , shear strength, compression ratio of the key parameters and spring rate , abrasive grinding of these organizations as a semi- fixed abrasive grinding evaluation index , Construction of the evaluation system of semi- fixed abrasive grains . According to the characteristic parameters of semi- fixed abrasive abrasive grit to establish a semi- fixed abrasive PFC models.
