摘要：硬质合金是以高硬度难熔金属的碳化物微米级粉末为主要成分，以钴或镍、钼为粘结剂，在真空炉或氢气还原炉中烧结而成的粉末冶金制品。硬质合金可用来制作凿岩工具、采掘工具、钻探工具、测量量具、耐磨零件、金属磨具、汽缸衬里、精密轴承、喷嘴等。因为硬质合金等的广泛应用，来修整硬质合金的砂轮也就越来越多了。金刚石砂轮是节能环保产品，使用安全、操作简单、能显著提高生产效率和产品质量，降低产品制造时间成本，极易于被操作工人所接受。随着工业的发展，越来越多需要用硬质合金来加工零件，由此来修整硬质合金刀具就要靠金刚砂轮来加工。比如钻头的退刀槽，螺纹钢的制造，罐头等都需要用金刚砂轮来加工，特别是加工带有圆弧的硬质合金工件，其最佳方法就是用带有同样圆弧的金刚砂轮来加工。我的研究就是金刚砂轮修整机往复机构及投影机构的设计。35820

The design for the crank rod system of a Emery wheel machine repaired and projector
Abstract:Hard alloy is high hardness of infusible metal carbide powder for main components microns，Nickel or cobalt in molybdenum as binder，In a vacuum furnace sintering furnace or hydrogen reduction of powder metallurgy products。Hard alloy used to make drilling tools, mining tools, drilling tools, measuring tools, measuring tools, wearing parts, metal cylinder liner, precision bearings and nozzle, etc. Because of the extensive application of carbide, to trim carbide grinding wheel is increasing. Diamond grinding wheel is energy-saving and environmental protection products, the use of safe, simple operation, can significantly improve the production efficiency and product quality, reduce cost, manufacturing time very easily accepted by operators. With the development of industry, more and more carbide processing parts, thus to trim carbide cutting tools will depend on the emery wheel to processing. As the groove of the drill out, the manufacturing, canned rebar with emery wheel etc are needed to process, especially the processing of arc workpiece with its best carbide method is to use the same emery wheel with circular arc to processing. I study is emery wheel repairing the crank rod system and the design of the projector system .
