Machine Tool Features 机床特点
Max. feature of this serial product lies in the fact that it has no special requirements to the processed metal material properties. In principle, it can process all the conductive materials such as super-hard and hard alloy, quenching materials, stainless steel ductile materials, various magnet steel fragile materials, uneasily-clamped thin wall spares etc. If the Machine Tool gets the aid of the auxiliary extra-large specification of “Taper Cutting Device” and “Responsive Micro-Computer System” produced by this Company, then it can gain the satisfactory results in processing all kinds of the special spares which terrify other Machine Tools. Following the constant appearance of the high-tech products, it continuously prospers the national economy. We predict that the characteristics of this serial product will be further developed and utilized. It will find favor in the eyes of vast customers.
本系列产品最大特点是对被加工的金属材料性质无特殊要求，原则上凡导电材料均可加工。

Structure and Principle of Operation 工作原理及结构
Principle of Operation 工作原理
The serial product applies “Electrical Discharge Machining” mechanism. It gets the auxiliary aid from electro-mechanically integrated product which combines Automated Control with Micro-Computers. The Machine Tool usually adopts “Molybdenum Wire” or “Hard Brass Wire” as the “Tool Electrode”. Under the “High Frequency Pulse Voltage Functions”, it utilizes the effect that it forms “Spark Discharge” after the liquid medium has been broken down. It instantaneously produces great volumes of heat energy in the Spark Channel. It melts or even gasifies the metal in the surface of the Work-Piece. With the joint action of the liquid medium, the metal has been rapidly eroded and removed. The Work-Piece which has been chucked in the coordinates Work-Table has been processed into various required shapes according to the pre-formulated program under the Micro-Computer Control.
本系列产品是应用“放电加工”机理，辅以自动控制及微机相结合的机电一体化产品。机床通常采用钼丝或硬性黄铜丝作为工具电极，在高频脉冲电压作用下，利用液体介质被击穿后形成火花放电，在火花通道中瞬间产生大量的热能，使工件表面的金属熔化甚至气化，加上液体介质的共同作用，而使金属被迅速蚀除下来。装夹于座标工作台上的工件在微机控制下按预行编制的程序被加工出各种所需的形状。
