First, the WEDM machine 
 1, top of the WEDM machine 
 Switzerland, Japan made the WEDM machine 
 Represents the highest level of the wire cutting machine, such as the Swiss company Shamir 1000 series WEDM machine, Japan MITSUBISHI Motor Company PA series ultra high precision WEDM machine, Japan Makino company UPJ-2 ultra precision WEDM machine etc.. This kind of WEDM machine is the biggest characteristic of high precision machining, within 0.002 mm, surface roughness Ra<0.2 mu m, the electrode wire can generally use 0.03 mm micro machining, mostly with the host system heat balance, some of the WEDM machine by cutting processing in oil. Double wire WEDM machine Switzerland Archie Chamfer company also belongs to this class. The grade of the medium-sized WEDM machine each priced at 2 million yuan in general. 
 2, mid-range WEDM machine 
 In addition to mid-range WEDM machine with no resistance anti electrolysis power supply, generally with automatic wire threading device, the wire electrode can be used for cutting precision of 0.10 mm, about 0.003 mm in. The highest processing efficiency can reach 500 mm2/min ultra high speed machine also belong to this class, such as the Shamir company's 240CC, 440CC, Japan's MITSUBISHI motor company's FA-V ultra high speed high performance machine, etc.. This grade of medium-sized machine tools at more than 1 million yuan per unit. 
 3, low-end WEDM machine 
 In order to seize the market China, machine manufacturing enterprises of Japan and Switzerland launched the EDM WEDM machine, the price is generally 50 ~ 800 thousand yuan / taiwan. Such as XENON wire walking, Switzerland's Shamir's 380 wire walking, Sadegh of Japan's AQ series, MITSUBISHI Motor Company FA series, Taiwan Qinghong silk etc.. Such machine tools in general by these companies in China set up factories manufacturing, such as the Beijing Archie Chamfer company, Dalian Mitsubishi Co, Suzhou Sadegh special. 
 The configuration and performance of the WEDM machine to meet the basic requirements of users with low speed WEDM machining. Generally use no resistance, anti electrolytic power supply, with water immersion type processing, taper cutting function. The highest machining efficiency for utility 120 ~ 150 mm2/min, the best surface roughness of Ra is less than 0.5 m, the cutting accuracy of 0.005mm, generally by more than 0.15 mm wire cutting. This gear machine tool generally have automatic threading function, can be used for user matching. 
 The highest machining efficiency of Taiwan wire is about 200 mm2/min in the practical machining efficiency is 100 ~ 150 mm2/min, the cutting surface roughness of Ra 0.5 ~ 0.8 M. Is generally believed that the cutting precision of wire walking in Taiwan should be about 0.005 mm. 
 As of 2014 two, the WEDM machine is currently in the market share of Chinese 
 Ching hung wire walking 1, Sadegh in Japan and Taiwan in the silk China the highest market share 
 The occupancy rate of the two kinds of machine tools is about 50% 
 2, Japan's MITSUBISHI laitong EDM wire walking, Taiwan, Su - wire walking, made Shamir walking silk 
 The occupancy rate of the four kinds of machine tools is about 35% 
 3, other such as fanvc wire walking, Western Makino EDM wire walking, etc. the market share of only 15% 
 Three, the world's grain and machine tool manufacturers cooperation 
 Setagaya and above all large WEDM machine enterprises, there are different levels and depth of cooperation in line, which also represents the Setagaya brass line, coating line has been the WEDM machine manufacturing enterprises widely recognized!
