MRF polishing technology is the use of a magnetorheological fluid rheology

Abrasive magnetic fluid in the case of an external magnetic field without the performance of a general fluid state, has a good fluidity, and once it is applied to the external magnetic field will rapidly increase the viscosity, exhibit solid-like properties, which is a liquid abrasive magnetic rheology. Currently MRF polishing  synthetic diamond powder  the use of a magneto-rheological fluid rheology, but the technology is also limited to optical lenses, ceramics, glass and some other non-metallic materials, parts of the surface grinding. This thesis is in the full use of  Abrasive grinding  abrasive fluid rheology basis, in order to achieve the metallic materials, especially  Diamond blade  parts of the surface finishing, while presenting a liquid magnetic abrasive finishing technologies. By analyzing the composition of liquid and characteristics of magnetic abrasive, abrasive magnetic fluid obtained finishing machining technique works.

Abrasive is to combine a boehmite, aluminum hydroxide and magnesium nitrate combined with the product

Abrasives grown in an aqueous gel abrasive abrasive technology has been considered a big step forward. Ministry of Industry abrasive early in the 1980s began using sol-gel processing method to generate an abrasive. Mineral technology manager explained, The abrasive is to combine a boehmite, aluminum hydroxide and magnesium nitrate  polycrystalline diamond  product. Magnesium nitrate is used as a modifier. These gel generated on the liquid taken out, allowed the formation of massive precipitate. then it is crushed into a desired size. And finally into the furnace calcination. This has been improved, like the very dense ceramic corundum abrasive as new. The sol-gel method of the production of  synthetic diamond  corundum normal  abrasive grinding  compared to the advantages of a gel abrasive after calcination in the broken, thus eliminating the micro-cracks. Abrasive micro-cracks on the grinding pressure, causing premature wear of the main factors abrasive.

Abrasives Abrasives Company as an example to corporate tax planning for diagnostic studies

Abrasives company is state-owned enterprises from the past of modern enterprise system from the restructuring abrasives business, business tax planning lack of due attention, do not attach importance to the use of modern enterprise financial system, leading to high cost of corporate tax, the lack of financial competition advantage. This thesis is divided into five chapters, for example on the company Abrasives Abrasives  synthetic diamond  for diagnostic studies. The first chapter of the world and China Abrasives production and development trend analysis, the use of the five competitive  synthetic diamond powder  analysis of the abrasives industry competition, combined with the characteristics of the industry for the abrasives industry conditions, industry tax analysis of the characteristics; the second chapter reviews the related research and foreign tax planning, tax planning summed up the basic theory, combined with characteristics of abrasives industry, analysis of the use of tax planning; abrasives company's operating condition, tax features, and then combined with enterprise systems analysis features the BG abrasives company tax planning space;

Abrasive abrasive bending theory and design

Consider the workpiece from the initial processing to the sphere in the process of removal of the paraboloid and to establish the mathematical model and the ideal state derived abrasive density trend. Bending theory expounded abrasive and grinding tools, design,  abrasive wheels  of the abrasive abrasive on uneven density distribution method. The use of such  abrasive grinding  density abrasive grinding test results are analyzed and the theoretical calculation of worn grinding parabolic  synthetic diamond , the same as the general conditions using abrasive uniform density results, the conclusion is : the calculated density abrasive trend is positive, and the use of production based on this theory for parabolic speed grinding abrasive, abrasive wear can reduce the degree of unevenness, reducing the number of abrasive trimming.

Abrasive water jet theory and research status, proposed hydraulic squeeze-type abrasive water jet system model

Engineered and tested hydraulic squeeze-type abrasive water jet equipment prototypes. Come up with a site can be used for disaster relief, and penetration, crushing various materials (such as steel, steel, concrete, rock, etc.) hydraulic squeeze-type abrasive water jet way and equipment. This paper discusses the abrasive water jet  abrasive grinding  theoretical and research status, proposed hydraulic squeeze-type abrasive water jet system model, and use the theory of transient flow system is analyzed. Hydraulic squeeze-type abrasive waterjet system uses a small horizontal  lycrystalline diamond  abrasive chamber confining pressure from environmental media on the resistance caused by the jet. Environmental conditions at high confining pressure dynamic pressure under the jet axis apparent than in the non-confining pressure decay much faster;

High-pressure water jet rock breaking theory and its application in underground engineering basic research

Traditional abrasive water jet technology pump pressure, high cost, energy consumption, bulky and sophisticated system, not suitable for the application of post-disaster rescue scene. By the National Natural Science Foundation of Innovative Research Groups fund "high-pressure water jet rock breaking theory and its application in  abrasive wheels  engineering basic research" and the nation-building project level Graduate Students relying on the traditional premixed abrasive water jet  synthetic diamond  proposed a new type of hydraulic squeeze-type abrasive water jet formation mechanism and equipment for research; built hydraulic squeeze-type abrasive water jet system model; carry out the system's abrasive jet formation mechanism and abrasive nozzle wear mechanisms visualization experiments research;

Abrasive water jet cutting mechanism and key techniques of engineering ceramics research is still far from fully

Processed with special high quality and high performance of the new engineering ceramic products. It is widely used in machinery, electronics, aerospace, defense industry, bio-engineering and other fields. At present, China in abrasive waterjet  synthetic diamond powder  ceramics mechanism and key technology research is far from sufficient, domestic Abrasive water jet equipment mainly rely on imports. Furthermore, since the lack of abrasive water jet cutting depth study of the mechanism, the introduction of  synthetic diamond  has not been fully utilized, processed products of quality, efficiency and cost associated with the developed countries there is a large gap. Therefore, this study and further promote the implementation of the outcome, will increase the processing capacity of engineering ceramic products and expand the application fields of engineering ceramics.
