摘要:硬質合金是以高硬度難熔金屬的碳化物微米級粉末為主要成分,以鈷或鎳、鉬為粘結劑,在真空爐或氫氣還原爐中燒結而成的粉末冶金制品。硬質合金可用來制作鑿巖工具、采掘工具、鉆探工具、測量量具、耐磨零件、金屬磨具、汽缸襯里、精密軸承、噴嘴等。因為硬質合金等的廣泛應用,來修整硬質合金的砂輪也就越來越多了。金剛石砂輪是節能環保產品,使用安全、操作簡單、能顯著提高生產效率和產品質量,降低產品制造時間成本,極易于被操作工人所接受。隨著工業的發展,越來越多需要用硬質合金來加工零件,由此來修整硬質合金刀具就要靠金剛砂輪來加工。比如鉆頭的退刀槽,螺紋鋼的制造,罐頭等都需要用金剛砂輪來加工,特別是加工帶有圓弧的硬質合金工件,其最佳方法就是用帶有同樣圓弧的金剛砂輪來加工。我的研究就是金剛砂輪修整機往復機構及投影機構的設計。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 . 源`自*六)維[論*文'網www.aftnzs.live
