喷砂加工是工业生产中广泛采用的一种表面处理方法。但传统的干式喷砂加工存在很多弊端,如加工时因砂粒高速撞击金属表面,容易破碎而产生大量粉尘,污染环境,危害工人键康;所选用的磨料粒度较粗,加工后表面粗糙,不能加工高精度的零件;大最砂粒成为粉尘被排除,磨料消耗量大,使用成本高。因此干式加工方法,已不能适应现代化技术发展和文明生产的要求。为此,发展了液体喷砂(丸)又称湿喷砂(丸)方法。航空航天工业部北京长空机械厂于1983年研制成功SS_1型液体喷砂机。1984年该厂与英国合作,陆续生产了SS_2,SS_3、SS_5等大、中、小系列产品及行业专用 Sand blasting is a widely used surface treatment method in industrial production. However, the traditional dry sandblasting has many disadvantages. For example, high speed sand blasting on the metal surface during processing can generate large amounts of dust and easily pollute the environment and endanger the health of workers. The selected abrasive grains are coarse, the surface rough after processing, Can not process high-precision parts; the largest sand particles to be excluded as dust, abrasive consumption, high cost. Therefore, the dry machining method can no longer meet the requirements of modern technological development and civilized production. To this end, the development of liquid sandblasting (pill), also known as wet blasting (pill) method. Aerospace Industry Beijing Air Machinery Plant in 1983 successfully developed SS_1 liquid sandblasting machine. In 1984, the factory cooperated with Britain and successively produced large, medium and small series of products such as SS_2, SS_3 and SS_5
