【正文】 el with various wheels in the same grinding conditions. (2) record data and pute the grinding ratio of various wheels. (3) measure the surface roughness of the heatresisted steel ground by various wheels. (4) observe dulling and pullout of abrasive grains of various wheels by using optical microscope. in this part, we can conclude that electroplated wheels have far better grinding abilities than other wheels, by paring parameters, such as grinding ratio, surface roughness etc. the final assignment of the project is to find out the most suitable parameters of grinding heatresisted steel with electroplated cbn wheels, through paring the grinding ratio and surface roughness of heatresisted steel ground in different grinding parameters. by investigating the attributes of electroplated cbn wheels and concluding their practical grinding parameters, this project is very important in promoting the application of them.china’s unique advantage of labor force predicts the resplendent future of its mechanical engineering, especially the manufacture, and it is our belief that this day will e soon. on the other hand, there are so many experienced technicians in china, however, with the absence of advanced experts many advanced producing method cannot be used in practical yield. when i worked as intern in some factories, i found that most of them were still using facilities which were used in america about thirty years ago. therefore i want to use the advanced knowledge earned in united states, bined with my acquaintance with china, to improve the present situation and apply best the advanced scientific technology to practical social wealth as soon as possible. i hope to bee a successful researcher in mechanical engineering, the arduous but exhilarative field. the significant progress achieved in , with the extraordinary cultural and intellectual sources in your university, has attracted me greatly. based on the study and the research experience in _ university, i am sure that i am qualified and would be an outstanding . student. with the advanced courses, balanced program and distinguished faculty of your department, i would get a solid background for my future academic career.yours sincerely,xuexila
