    • There is disclosed an apparatus for giving a satin finish to the surface of a crowned roll. A plurality of electrode heads are divided and arranged along the axis of rotation of the crowned roll to be worked, and one or a plurality of rectangular electrodes are mounted at a predetermined spacing on each of the electrode heads. The discharge gap of each rectangular electrode is controlled by a servomechanism at a predetermined value and it is also fed traversely a predetermined distance by a traverse feed mechanism. The electrode is rectractably mounted on the electrode head and it is fixed in position so that the discharge surface of the electrode is projected into contact with the roll surface of the crowned roll. The discharge electrode surface of each rectangular electrode is initially flat and this discharge surface is consumed to conform with the shape or contour of the roll surface upon initiation of discharge.
    • 公开了一种用于在凸起的辊的表面上提供缎面光洁度的装置。 多个电极头沿被加工的加工辊的旋转轴线分开布置,并且在每个电极头上以预定的间隔安装一个或多个矩形电极。 每个矩形电极的放电间隙由预定值的伺服机构控制,并且还通过横动进给机构横向预定距离进给。 电极可直接安装在电极头上,并将其固定在适当的位置,使得电极的放电表面突出与凸面辊的辊表面接触。 每个矩形电极的放电电极表面最初是平坦的,并且在放电开始时,该放电表面被消耗以符合辊表面的形状或轮廓。

    • Disclosed are a process and apparatus for subjecting the outer surface of a satinizing roll to electrical discharge machining to produce a satin-like roughened surface of a uniform roughness. With this electrical discharge machining process, the electrical discharge machining speed of a plurality of electrodes mounted on a plurality of head columns is held lower than a steady state working speed until the electrodes on all the head columns start discharging, and in response to the detection of the discharge of every electrode on the head columns the working speed is changed to the steady state working speed and the head columns are simultaneously moved traversely along the axis of rotation of a cylindrical work, thus preventing the occurrence of a difference in the depth of erosion or stepped portions on the surface of the work during the initial working period. The apparatus for performing this electrical discharge machining process comprises a working power source including means for controlling the working speed, and detecting means for detecting that every electrode has started discharging so as to direct the working power source to change the working speed and so as to simultaneously actuate a head column transverse feed unit.
    • 公开了一种使饱和辊的外表面进行放电加工以产生均匀粗糙度的缎状粗糙表面的方法和装置。 利用该放电加工工艺,安装在多个头列上的多个电极的放电加工速度保持低于稳态工作速度,直到所有头部柱上的电极开始放电,并且响应于检测 在头柱上的每个电极的放电,工作速度变为稳态工作速度,并且头柱同时沿着圆柱形工件的旋转轴线横移移动,从而防止了深度的差异的发生 在初始工作期间工作表面上的侵蚀或阶梯部分。 用于执行该放电加工工艺的装置包括工作电源,包括用于控制工作速度的装置,以及检测装置,用于检测每个电极已经开始放电,以便引导工作电源改变工作速度,并且 同时致动头柱横向进给单元。
