主要功能及特色

The DK77 series of electrical discharge wire-cutting machine tools with numerical control are mainly composed of parts such as the machine body (base), coordinate worktable, wire-feeding mechanism, wire holder, working fluid circulation system, electrical components of the machine tool, and numerical control system. The coordinate worktable is controlled by the numerical control system, which drives the workpiece to make precise longitudinal and transverse movements along the given trajectory. The electrode wire makes high-speed reciprocating movements through the wire holder, upper and lower guide wheels from the wire-feeding and wire-storage drum. During processing, high-frequency pulsed spark discharges occur between the electrode wire and the workpiece. High temperatures are generated at the center of the spark discharge channels, melting the metal and generating electroerosion products that are then discharged, thus achieving the purpose of processing.
DK77系列电火花数控线切割机床主要由床身（基座）、坐标工作台、运丝机构、线架、工作液循环系统及机床电器、数控系统等部分组成。坐标工作台由数控系统控制，带动工件按给定轨迹作纵横向精确移动：电极丝由运丝贮丝筒经线架、上下导轮、作高速往复运动。加工时，电极丝与工件之间进行高频脉冲火花放电，火花放电通道的中心产生高温，使金属熔融，生成电蚀产物而排出，从而达到加工目的。
