近15年来,国外砂带磨削技术获得了极大的发展,广泛用于各行各业,尤以机械工业最为突出。砂带磨削的加工效率几乎超过了常规的车、铣、刨、磨等工艺。加工精度及光洁度已与同类型的砂轮磨床相当,而且砂带磨床结构及装备简单,加工成本比铣削还低。砂带磨削具有独特的工艺性能,比其它机加工工艺有更大的灵活性。在金属切削机床构成比例中,砂带磨床几乎接近砂轮磨床。近几年来国内已开始重视研究和应用砂带磨削工艺,并取得了一些成绩,但与国际先进水平还相差甚远。为推动砂带磨削技术在我国的应用和发展,本文拟介绍砂带、砂带磨削及其发展概况。
In the past 15 years, foreign belt grinding technology has gained great development and is widely used in all walks of life, especially in the machinery industry. Belt grinding efficiency is almost beyond the conventional car, milling, planing, grinding and other processes. Processing accuracy and finish with the same type of grinding wheel grinder and belt grinder structure and equipment is simple, the processing cost is lower than milling. Belt grinding has a unique process performance, greater flexibility than other machining processes. In the composition ratio of metal cutting machine tools, belt grinders almost grinding wheel grinder. In recent years, China has begun to attach importance to the study and application of belt grinding technology, and achieved some results, but still far cry from the international advanced level. In order to promote the application and development of belt grinding technology in our country, this paper intends to introduce the belt and belt grinding and its development overview.
