D6140A高频电火花机床主要用来加工淬火钢及特殊金属材料的型腔模,亦可加工冲模或异形零件。本机床采用晶体管脉冲电源,其脉冲参数调节范围宽,能分别达到电极损耗小、生产率高、光洁度高、兼顾粗、中、精加工的主要指标。自动进给系统采用液压主轴头,因此控制灵敏,加工稳定,并配有平动头、冲(抽)油杯、电极重复装卡夹头、电极周期提升等附加装置,适宜加工精度要求较高的中小型型腔模。为了进一步扩大使用范围,机床上增添了一套高压附加回路,改善了铸铁及钢电极加工稳定性。该机床经生产实践证明,用来加工模具可以大大减少劳动强度,缩短模具制造周期,降低模具制造成本。由于电火花加工方法是一种较新的工艺,为使该机床能更快更好地用于生产,兹介绍一些工艺性能与加工实例,供使用单位参考。
D6140A high-frequency EDM machine is mainly used to process hardened steel and special metal cavity mold, die or profiled parts can also be processed. The machine uses transistor pulse power supply, the pulse parameter adjustment range, respectively, to achieve small electrode loss, high productivity, high finish, taking into account the rough, the main indicators of precision machining. Automatic feed system with hydraulic spindle head, so the control of sensitive, stable processing, and with the translation head, red (pumping) oil cup, the electrode repeat chuck clip, the electrode cycle to enhance additional devices, suitable for processing high precision Small and medium cavity mold. In order to further expand the use of the machine, adding a set of high-pressure additional circuit to improve the stability of cast iron and steel electrode processing. The machine proved by the production practice, used to process the mold can greatly reduce labor intensity, shorten the mold manufacturing cycle, reduce mold manufacturing costs. As the EDM method is a relatively new technology, in order to make the machine can be used faster and better for production, it is introduced some process performance and processing examples for the use of units for reference.
