电火花加工是利用在介质中两极间的火花放电来蚀除金属的。由于它具有能加工任何硬度的金属,电极形状能精确复制在工件上以及放电间隙均匀恒定等特点,因而在某些机械加工难以胜任的场合发挥其特殊的作用。齿轮电跑合即是将电火花加工与齿轮跑合相结合的一项新的加工工艺,它能有效地解决齿轮的接触精度问题。电火花加工为非接触加工,而跑台时主、从齿轮副问各对齿需相接触方能进行力的传递,这样似无法进行电火花跑合加工。但是,通过试验可以发现,在
EDM is the use of dielectric discharge between the poles to erase the metal. Because of its ability to process any hardness of the metal, the electrode shape can be accurately replicated in the workpiece and the discharge gap uniform and so on, so in some mechanical processing is not competent for the occasion to play its special role. Gear running is the combination of electric spark machining and gear running a new combination of processing technology, which can effectively solve the problem of gear accuracy of contact. EDM for non-contact processing, while the main treadmill, from the gear pair asked each tooth to be in contact with the force transmission, it is not possible to EDM run together. However, through the experiment can be found in
