External positioning is another positioning method is the use of the board externally applied positioning hole as the positioning holes of paneling. The advantage is easy to manage, if pre-production specification is good, paneling template is generally about 15 species. The use of external positioning can not time the board milling CNC drilling down, otherwise it is very easy to damage the circuit board, in particular puzzle, because the cutter and suction device will cause the board with a circuit board damage and milling broken. The use of sub-milling methods remain binding sites, the first paneling paneling When finished program pause The plates were then secured with tape, and the second execution of the program, the use of 3mm to 4mm drill to drill out the point of integration. The advantage is cost little less easy to manage templates can be milled in all plate without mounting holes and positioning holes in the circuit board high-speed CNC drilling, small craft to easily manage, especially pre-production CAM and other production staff can simplify flange NC drilling, while optimizing the utilization of the substrate. The disadvantage is that the use of the drill, the board shape allow at least 2-3 points raised unsightly, may not meet customer requirements, milling long time, labor intensity slightly. The CNC system using Spain FAGOR8055 system (or above grade brand), and is equipped with an RS232 interface and LCD display, the host computer management plane CNC drilling, drilling coordinates can achieve CAD / CAM direct conversion, easy programming, storage, display and communications, man-machine dialogue interface, error compensation, automatic alarm functions. Workpiece hole after machining program can be automatically generated or CAD floppy keyboard input. It includes drilling holes preview and review before, easy to operate. CNC console mounted on the gantry, movable longitudinally with the gantry, easy to operate.
