Preparation Of Sub-millimeter Diamond Fiber Grinding Wheels And Study On Its Face Grinding Performance

On the base of our project team’s preliminary work, the new diamond wheel with1.5mm parallel interval arrangement was prepared successfully and grindingperformance of the new diamond wheel was studied. On this basis, the further studywas carried out. I proposed and prepared sub-millimeter diamond fiber as the cuttingedge. Firstly, the two key process, that is the injection molding process and thedebinding process were studied, and the preparation process parameters of two keyprocess respectively were identified. Secondly we designed new diamond fiber wheelwith new grid arrangement, the successful preparation of the sub-millimeter gridarrangement of the way the diamond fiber wheel. When we successfully preparedsub-millimeter diamond fibe grid wheel, we carried out comparative experiments withparallel rows diamond fiber wheel with1.5mm interval under the same experimentalconditions and further analysis of its grinding performance.In the process of preparation of the diamond fiber, injection molding is one of thekey processes. When the mold temperature is40°C, injection pressure is12MPa, theinjection temperature is150°C, the injection rate is50%, the diamond fiberrough-body during injection molding is dense, and there is no pores, holes and otherdefects drawn through the experimental study, the injection effect is very good.Debinding process is one of the critical process of the sub-millimeter diamondfiber preparation.This Debinding process had a thorough discussion.Through a lot ofexperimentswe examined the relationship between solvent debinding rate and time andtemperature, and we carried out the solvent debinding green body ‘s fracturemorphology analysis to determine the solvent debinding process.using integratedthermal analyzer,we analyzed the thermal performance of the feed, eventually throughexperiment analysis of thermal debinding fracture morphology,we determined thethermal debinding process.The macro landforms fiber arrangement of the wheel cylindrical surface is animportant factor in determining the wheel processing performance. In order to obtainthe good processing effect, diamond fiber arrangement of the new diamond fiber wheelis the key factor in the grinding process. From the diamond fibers arranged programdesign,in my paper,I had a detailed analysis of its advantages and disadvantages ofaxial parallel interval arrangement as well as finally we successfully preparedsub-millimeter diamond fibe grid wheel with raster arrangement. When we successfully prepared sub-millimeter diamond fibe grid wheel,wecarried out comparative experiments with parallel rows diamond fiber wheel with1.5mm interval under the same experimental conditions and further analysis of itsgrinding performance. The experimental results show that: compared to the diamondfiber wheel with1.5mm intervals parallel arrangement, the grinding force of thediamond fiber wheel with sub-millimeter grids and raster arrangement is smaller,processing quality is better than the former.
