摘要： A workpiece-supporting table of an electro erosion machining equipment is provided with a mechanism for subjecting the workpiece to a circling motion of continuously variable radius during operation from zero to a maximum value. The same tool electrode can be used, without withdrawal from the work, for coarse machining at first and fine machining under circling movement immediately thereafter.

摘要： A movement control apparatus, which can be constructed as an accessory, provides in addition to the primary process-controlled movement of the electrode circular a secondary movement. The secondary movement is imparted to the electrode through a drive arm fixed at one end to the bottom slide of a cross-slide on which the electrode is also fixed and attached pivotably at the other end to an eccentric point of a rotating spindle. The mechanism for rotating the spindle is so designed that the degree of eccentricity of the eccentric point may be adjusted mechanically while the spindle is rotating. The eccentricity may also be controlled by the action of a cam follower which runs along a template, so that the circular movement of the electrode is controlled by the template in a copying mode. Further described are means for deflecting the primary process-controlled movement of the electrode to the secondary movement, so that the secondary movement can be process-controlled by the existing control mechanisms of the machine.The present invention relates generally to apparatus for spark erosion machining, also known as EDM (Electrical Discharge Machining). It relates particularly to EDM apparatus with the capability of supplementing the main, primary movement between the tool electrode and the workpiece with a secondary movement, such as one transverse to the primary movement.

摘要翻译： 可以构造为附件的运动控制装置除了电极的主要过程控制运动之外还提供辅助运动。 二次运动通过一个固定在横向滑动件的底部滑动件上的驱动臂固定在其上，其中电极也固定在其上，另一端枢转地附接到旋转主轴的偏心点。 用于旋转主轴的机构被设计成使得当主轴旋转时可以机械地调节偏心点的偏心度。 偏心度也可以通过沿着模板延伸的凸轮从动件的作用来控制，使得电极的圆周运动由复印模式中的模板控制。 进一步描述的是用于将电极的主要过程控制的运动偏转到次要运动的装置，使得二次运动可以由机器的现有控制机构进行过程控制。 本发明一般涉及用于火花冲蚀加工的设备，也称为EDM（放电加工））。 特别涉及具有补充工具电极和工件之间的主要主要运动的能力的电火花成型设备，其具有辅助运动，例如横向于初级运动的一次运动。
