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.

Mechanical parts surface finishing field of research and development has rolling mill, magnetic grinding, honing squeeze

Mechanical parts surface finishing field has research and development of new technology, new methods rolling mill, magnetic grinding, extrusion honing, electrolytic chemical polishing, ultrasonic polishing, each method of solving certain problems have very good results. However, whether it is the traditional method or the recently  synthetic diamond powder  are deficient, such as the processing of irregular surfaces, poor control more difficult and do not have the full capability of precision optical cavity surface. This is an urgent need to develop new, more  polycrystalline diamond  to the problem of new abrasive and finishing processes. Compared with the traditional processing methods, magnetic liquid abrasive finishing method has unparalleled advantages, its advantages body in liquid magnetic abrasive finishing method is suitable for finishing outside the irregular surface of the part and the cavity, which because the magnetic grinding fluid rheology, before applying the magnetic field which is a good flow of the liquid, and can fully contact with the cavity surface of the workpiece;
