Abstract: A pressure foot (7) of a perforating machine for a printed board, which is supported axially slidably on a spindle (2) of the same machine, and has a presser surface (13) for press holding a printed board (5) during perforating process, a discharge port (11) formed in a side wall (8) for discharging cutting chips produced by processing for perforation, the discharge port (11) being connected to a suction device, and a compressed air supply passage (20A) formed in the side wall for blow out compressed air toward a drill (4) of the perforating machine for a printed board. A cooling liquid supply device (21) is connected to the compressed air supply passage (20A). A liquid supply passage (14) for injecting cooling liquid toward the drill (4) of the perforating machine for aprinted board may be formed instead of the compressed air supply passage (21A). In this case, there is formed at least one groove (18) extending in the direction of a tangent to the drill (4) for allowing air to be sucked into the interior (10) of the pressure foot in the presser surface (13). This enhances cooling efficiency during perforating process.

Abstract: A main CPU unit is connected through a but to a plurality of CNC units which correspond to machine tools. The main CPU unit is also connected to an external storage and to an input device. When operation control of the machine tools and machining data of works are changed, a new system program is down-loaded to CPU for the CNC units from the external storage through RAM of the main CPU unit to modify a part program, containing machining data, which is usually stored in the CPU for the CNC units.

Abstract: This invention relates to a board holder in a printed board boring machine and the holder has the following construction: upper board holders (33, 41, 45, 52, 56) whose tip surfaces project from the contact surface with a printed board (1) towards a table (6) are disposed outside the contact surface in such a manner as to be movable in an axial direction thereof and biasing devices (31, 40, 50, 55) for biasing the upper holder (33, 41, 45, 52, 56) with a force greater than attraction generated in the board holder (18) towards the table (6) are disposed. According to this construction, floating of an upper plate (2) at the time of boring of the printed board (1) can be prevented and boring efficiency can be improved by minimizing a wasteful moving distance of a drill (16).
