电火花线切割机由于受到诸多因素的影响,一般难以达到高精度。目前其加工精度为0.005～0.01mm,极个别可达0.003mm;我国的还要低,一般为0.01～0.02mm。 最近,日本三菱电机公司开发了PX05型超高精度电火花线切割加工机。这是三菱电机公司继“DIAX”系列的DWC110PA型和DWC90PA型高精度线切割机之后的最高级机床,于1997年5月正式投放市场。 由于半导体工业的发展,迫切要求降低半导体存储器的精密模具的制造总成本。PX05型高精度线切割加工机就是迎合这种需要而研究开发的。该机由于采用了新结构和新技术,可实现高精度线切割加工。同时由于机床无需放置在专门的恒温室中,可减少为控制温度所花费的费用,使成本降低。
WEDM due to many factors, it is generally difficult to achieve high accuracy. At present its processing accuracy of 0.005 ~ 0.01mm, very few up to 0.003mm; our country is even lower, usually 0.01 ~ 0.02mm. Recently, Mitsubishi Electric Corporation of Japan developed the PX05 ultra-high precision wire-cut electric discharge machine. This is Mitsubishi Electric Corporation following the “DIAX” series of DWC110PA and DWC90PA-type high-precision wire cutting machine after the highest level of machine tools, in May 1997 formally put on the market. Due to the development of the semiconductor industry, there is an urgent need to reduce the overall manufacturing cost of precision molds for semiconductor memory. PX05 high-precision wire cutting machine is to meet the needs of research and development. The machine due to the new structure and new technology, high-precision wire cutting can be achieved. At the same time as the machine does not need to be placed in a special thermostatic chamber, you can reduce the cost of temperature control, the cost reduction.
