guided tours have become known. that come with a. or more he s _s drilling and / or milling tools having means are equipped "Such a drilling and / or milling device is arranged below and / or laterally movable workpiece plane of movement and can be moved by means of pressure-medium cylinder in the direction of the workpiece. These devices have the major disadvantage that their drilling and / or milling devices can only be moved in one dimension, as a result of which the workpieces to be machined have to be interrupted in the continuous movement in order to produce holes.

For each workpiece, the transport device of the device must be stopped in the area of the drilling and / or milling device, the workpieces are aligned for precise hole production and only then does the machining process take place _, which results in a low throughput and thus an inefficient working cycle of the device.

Furthermore, the known devices have given the need for complicated and many in number moving means _s such as pressure medium cylinders for the drilling and- / or 7rü.seinrichtungen a costly manufacturing and störungsjxnfällige "effect catfish ■." F '". - '■ " ""-

The object of the! Inflation is _s while avoiding the existing power cables to provide a device for drilling _s milling or the like "of holes in plate-shaped workpieces or the like» _{s s} trouble-free effect catfish and cost-effective production is a streamlined manner with a simple Aufba.u "

According to the innovation, a device for drilling * milling or the like. of holes in plate-shaped workpieces or the like. "With at least one ₃ multiple tools having and movable on the workpiece to be machined, driven drilling and / or milling device characterized by a drilling and / or milling device supporting the workpiece and running through the workpiece depending on the workpiece movement at a relative standstill to the workpiece movement on an arcuate path of movement forcibly guided feed device ο

In a preferred embodiment, the feed device can form a four-bar linkage which can be moved in the workpiece passage direction by means of the workpieces. _s whose werkstüekseitige pivot points on the drilling, and V or milling device is provided and this ■ .. opposing pivot points can be configured as a fixed bearing points (pivot points) "'_-. ........_. ^ -_ ^ - '
