    摘要: A method of machining the contour of a printed circuit board by effecting a relative feed movement between a rotating tool and the other periphery of the printed circuit board. The electrical current value of a drive motor for driving a spindle to which the tool is attached is detected and an operation is conducted for changing the machining condition in such a manner as to reduce the electrical current value of the spindle drive motor and, at the same time, for changing also tool diameter compensation amount to a value corresponding to the machining condition after the change, at every time the detected electrical current value has reached a predetermined current value immediately before tool breakage and repeatedly by a predetermined number of times.

    摘要: A work holding device used in an external form cutting machine for printed boards, the cutting machine including a work mounting table movable in X direction and a cutter mounting spindle movable in Y direction perpendicular to X direction, comprising holding device disposed above the table, pushing device for pushing said holding device, elevating device for raising and lowering said holding device. The holding device and the elevating device engage with each other slidably in a vertical direction with the pushing device interposed therebetween. By virtue of these arrangements, the printed boards are surely holded, resulting in an uniform cutting surface of piled printed boards. Holding pins used in prior arts for holding printed boards are not required, resulting in an improved operational efficiency of the cutting machine.

    摘要: A printed circuit board boring machine bores printed circuit boards stacked on a table, by a drill while pressing the printed circuit boards with a pressure foot. A piece having a hole through which the drill may pass is detachably mounted on a tip end portion of the pressure foot with a center of the hole being aligned with an axis of the drill. The piece may be attached to the pressure foot before the boring work so that the boards and the piece may be simultaneously bored by the drill while the hole in the piece may be used as a guide for the boring work of the boards.

    摘要: A tool holding device for use in a printed circuit board processing machine is provided with a record which is capable of storing data concerning the states of tools held on the tool holding device and data concerning processing conditions and which enables reading and updating of the recorded content through a communication with an external control device. Necessity for renewal of data registered in the NC device, which has to be executed in the known apparatus each time the tool holding device is exchanged, is eliminated thereby improving the rate of operation of the printed circuit board processing machine. In addition, the present invention enables an easy automatic replacement of tools when the lives of the tools are expired.

    摘要: The present invention relates to a printed circuit board presser device in a drilling machine. The board presser device is arranged such that it includes an axially movable upper-plate presser device which is provided on the outer side of a contact surface of the board presser device with a printed circuit board so that a top end surface of the upper-plate presser device extends to the side of a table beyond the contact surface; and an urging device for pushing the upper-plate presser device against the table by a force larger than an attraction force generated from the board presser device. With such construction, an upper plate is suppressed from floating during drilling the printed circuit board, and a distance of useless transfer movement of a drill decreased, to thereby improve an efficiency of a drilling operation.
