<p>PURPOSE:To provide a printed board machining device which can quickly drill workpieces with any diameter and save stage preparation time. CONSTITUTION:Drilling devices 21 to 23 and exterior machining devices 31, 32 are located along a transfer line 1. A printed board from a transfer device 4 is first machined by a free drilling device along the transfer line 1. It then advances along the transfer line 1 and is machined again by a free exterior machining device. It then advances along the transfer line 1 to a discharge device 5, where it is removed. Machining by each drilling device and exterior machining device is performed depending upon the results of the reading of an identifier on the printed board by means of an identifier reading device, and the transfer of printed boards and the supply and removal of printed boards to and from the machine are controlled by a control device 6.</p> |
