Low-speed wire-cut EDM wire cutter made in Switzerland and Japan

         (1) Top low speed wire EDM wire cutting machine

           This low-speed wire-cut EDM wire cutter represents the highest level at present, such as the Thousand-series machine tools of Schaum, Switzerland, the PA series of ultra-precision machine tools of Japan's Mitsubishi Electric Corporation, and the UPJ-2 ultra-precision machine tools of Japan's Makino. . The most important feature of this type of machine tool is its high precision. Within ±0.002 mm, the surface roughness Ra<0.2μm can be used for micro-finishing with <0.03 mm electrode wire. Most of the main engines have thermal balance system. Cutting in oil. The double-filament machine of the Swiss AgieCharmilles also belongs to this grade. The price of this type of medium-sized machine tools is generally more than 2 million yuan. Kunshan slow wire

(2) High-grade low-speed wire-cut EDM wire cutting machine

         In addition to the non-resistive anti-electrolysis power supply, this machine tool usually has an automatic threading device, which can be cut with 0.10 mm electrode wire with an accuracy of ±0.003 mm. Ultra-high speed machines with a maximum processing efficiency of 500 mm2/min are also included in this grade, such as Xia Mil's 240CC, 440CC machine, Japan's Mitsubishi Electric's FA-V super high-speed high-performance machine. The medium-sized machine tools of this grade are priced at more than 1 million yuan each.

(3) Mid-range low-speed wire-cut EDM wire cutting machine

         In order to seize the Chinese market, electric machine tool manufacturers in Japan and Switzerland have introduced this machine tool, and the price is generally 50-800,000 yuan/set. Such as XENON of Switzerland Archie, 380 of Xia Mier, AQ series of Sodick Corporation of Japan, FA series of Mitsubishi Electric Corporation, etc. These types of machine tools are generally manufactured by factories established by these companies in China, such as Beijing AgieCharmilles, Dalian Mitsubishi, and Suzhou Sodick Special.

The configuration and performance of this machine meets the basic requirements of users for low-speed wire-cut EDM. Generally, it adopts non-resistive and anti-electrolysis power supply, and has the functions of water immersion processing and taper cutting. The practical maximum processing efficiency is 120-150 mm2/min, the optimum surface roughness is Ra<0.5μm, the cutting precision is up to ±0.005mm, and the copper wire is generally cut with 0.15 mm or more. This machine usually has an automatic threading function that can be selected by the user.

The above three grades of low-speed wire-cut EDM wire cutters can also be called high-end machines, standard machines, and entry machines.
