传统的干式喷砂存在很多弊端,如加工时砂粒高速撞击金属表面,容易破碎并产生大量粉尘,危害工人健康;所选用的磨料料度较粗,被加工表面粗糙,不能用来加工高精度的零件;由于大量砂粒成为粉尘被排除,磨料消耗量大,成本高。因此沿用了近一个世纪的干式加工方法,已不能适应现代化技术发展和文明生产的要求。 液体喷砂(丸),就是为了解决干喷砂的弊端而发展起来的一种新技术。其基本原理是,利用磨液泵将具有一定浓度的磨液(砂水混合物)靠泵压或同时加压缩空气增压,从喷枪的喷咀中高速喷出,利用高速运动的砂粒或玻璃丸,对零件表面进行加工,达到表面清理强化或光饰的目的。这种方法,不损伤零件表面,基本上不影响零件尺寸精度,表面粗糙度在原基础上可以获 The traditional dry grit blasting has many disadvantages. For example, when sand is processed, the grit collides with the metal surface at high speed and is easily crushed and produces a large amount of dust, which may endanger the health of the worker. The selected abrasive material is coarse and the surface to be machined is rough and can not be used for processing high precision Of the parts; due to a large number of sand to be excluded as dust, abrasive consumption, high cost. Therefore, the method of dry processing adopted for nearly a century has failed to meet the requirements of modern technological development and civilized production. Liquid blasting (pill), is to solve the shortcomings of dry sand blast and developed a new technology. The basic principle is to use a slurry pump to a certain concentration of grinding fluid (sand water mixture) by pumping or pressurized air at the same time pressurized from the nozzle spray gun at high speed, the use of high-speed movement of sand or glass balls , The surface of parts for processing, to achieve the purpose of surface cleaning or decoration. This method, does not damage the surface of the part, does not affect the accuracy of part size, the surface roughness can be obtained on the basis of
