The invention relates to the field of pcb machining and cutting, in particular to a cutting device for pcb machining. According to the cutting device for pcb machining, the temperature of a milling machine tool bit can be more effectively reduced, the situation that the tangent plane of a pcb deforms can be reduced, and board chips can be more effectively blown away. A cutting device for pcb machining comprises a main frame, a rotating lead screw, a motor mounting frame and the like. The main frame is rotatably connected with two rotating screw rods, the two rotating screw rods are symmetrically arranged, and the main frame is fixedly connected with two motor mounting frames. An operator starts the servo motor and the fan, so that the tool bit cuts the pcb, the fan performs air cooling on the tool bit and blows away board chips, and therefore, the temperature of the tool bit of the milling machine can be more effectively reduced, the situation that the section of the pcb is deformed due ...
