无气喷砂机能对平板类金属工件进行表面清理、表面前处理、表面光饰等表面处理。无气喷砂机能够加工处理的平板类金属工件的尺寸：工件的宽度可以是600mm，1000mm，1250mm，1400mm，1800mm，2500mm；工件的长度不限。
目前金属或非金属平面的表面除锈、亚光效果处理的基本方式是化学方式和机械加工方式两大类。这两种方式都不同程度上存在环境污染、损耗多、效率低等问题。
喷砂的动力为采缩空气，在加工同样宽度的幅面时功率消耗较大，加工出来的表面的均匀性及光泽度偏差也较大。抛丸设备是由核心部件抛丸器采用离心抛射原理来处理工件，对工件形状及材质都有严格要求，且加工同幅面的工件时设备较大。这两种机械加工方式在加工薄板时都很难处理好变形问题。
无气喷砂机利用从高压风机吹出的气流在出砂口前端产生负压，吸动从砂嘴口落下的砂料，再在后续气流的推动下吹到工件表面，由于砂嘴的孔径一定且在下砂嘴本体上布置的间距一定，保证了吹砂加工的均匀性。其与已有技术相比，不需要酸碱腐蚀等化学处理，减少了环境污染，能耗较低；加工成本低，工件变形量小，产品表面加工效果均匀度高、表面质量好。
无气喷砂清理机应用于金属或非金属平面的表面除锈、亚光效果处理的机械方式加工等领域，例如钢板的除锈以及玻璃、铝板、不锈钢板和塑料板等亚光效果的加工处理。机械加工方式，目前国内大部分采用喷砂和抛丸，喷砂在加工同样宽度幅面的工件时因动力为压缩空气，所需功率大，加工出来的工件表面的均匀性和光泽度偏差量也较大；抛丸设备是由核心部件抛丸器采用离心抛射原理处理工件，对工件形状和材质都有要求，且加工同样宽度幅面的工件时设备较大。以上两种机械加工方式在加工薄板或超薄板时都很难处理好变形问题。
无气喷砂清理机的技术与已有技术相比，因具有表面加工均匀度高、表面质量好、能耗较低、工件变形量小、不需要酸碱腐蚀等化学处理的优点而减少了环境污染，同时加工成本低。其主要原理是利用从高压风机吹出的气流在出砂口前端产生付压，吸动从砂嘴口落下的砂料，再在后续气流的推动下吹到工件表面，由于砂嘴孔径一定且间距均匀，从而保证了吹砂加工的均匀性。技术优点为表面均匀性提高以及光泽度偏差降低，加工同样宽度幅面的工件时，所需能耗仅是常规喷砂加工的1/2。

Airless blasting machine for flat metal workpiece surface cleaning, surface treatment, surface finishing and surface treatment. Airless blasting machine is capable of processing the flat metal workpiece size: workpiece width can 600mm,1000mm,1250mm,1400mm,1800mm,2500mm; the length of the workpiece is not restricted.
The metal or non metal surface rust, Matt effect processing is the basic way of chemical and mechanical processing method of two categories. These two modes have different extent of environmental contamination, loss, low efficiency problem.
Blasting power for mining air, in the processing of the same width format when power consumption is larger, the processed surface uniformity and brightness deviation is larger. Shot blasting device is composed of the core components of shot blasting machine with centrifugal projection principle to the workpiece, the workpiece shape and material has strict requirements, and processing the same format when the workpiece equipment is larger. These two kinds of mechanical processing method in the processing of sheet metal are very difficult to deal with problems of deformation.
Airless blasting machine using high-pressure wind blown from the air flow in the sand outlet end generates negative pressure suction mouth, moving from the sand falling sand, then in the subsequent flow driven by blowing into the workpiece surface, since the sand mouth aperture and under the sand mouth body layout spacing, guarantee blowing sand processing uniformity. As compared with the existing technology, does not need the acid-base corrosion, chemical processing, reduce environmental pollution, lower energy consumption; the processing cost is low, the deformation of workpiece surface processing effect of small, product uniformity, good surface quality.
Airless blasting machine used in metal or non-metallic surface derusting, Matt effects processing mechanical processing and other fields, such as steel, aluminum, stainless steel cleaning and glass plate and plastic board and Matt effect processing. Mechanical processing, most of the current domestic blasting and blasting, blasting in the processing of the same width of the workpiece when power is compressed air, the required power big, the processed workpiece surface uniformity and brightness deviation amount is large; shot blasting equipment is composed of core part by centrifugal projection principle of Shotblast processing workpiece, to workpiece shape and materials are required, and the processing of the same width of the workpiece when equipment is larger. The above two kinds of mechanical processing method in the processing of thin or ultra-thin plate are very difficult to deal with problems of deformation.
Airless blasting cleaning machine technology compared with the existing technology, because of its surface processing uniformity, good surface quality, low energy consumption, small deformation of workpiece, does not need the acid-base corrosion chemical processing advantages and reduce environmental pollution, and low processing cost. Its main principle is to use from the high pressure wind blown from the air in the sand outlet end produce pay pressure, suction operated from the sand mouth falling sand, then in the subsequent flow driven by blowing into the workpiece surface, since the sand mouth aperture and uniform spacing, so as to ensure the uniformity of blown sand processing. Technical advantages of surface evenness is improved and the gloss deviation decreases, processing the same width of the workpiece, the energy consumption is only conventional sandblasting processing 1/2.
