In a lighting shop in Xi’an, eye-protection lamps accounted for 60% of the brand, there are five or six brands, each brand has launched eye protection lamp with different price, the price ranges from tens of dollars to several hundred dollars per unit. It has been learned from the merchants that the table lamp market is now very competitive and the product homogeneity is very serious, and it is difficult for consumers to distinguish between them.

EDM (electrical discharge machining), is a manufacturing process used to obtain a specific desired shape in metal by applying electrical discharges(sparks),When it comes to using electrical discharge machining, the water serves as a key component. To get the best performance from an Edm Machine, the water must be kept as clean as possible. During the EDM process, some of the metal goes into the water as small particles. The water is filtered and deionized(demineralized) in order to remove those metal atoms. Deionized water helps to promote a higher metal removal rate and enhances the machine`s capacity to deliver a more precise cut. So the EDM water filter is very important component for EDM water filtration system.
