Background technique
Pcb board is constantly reduced to densification, multiple stratification, miniaturization, pcb board line width and line-spacing, to manufacture PCB's
More stringent requirements are proposed for the precision and stability of machine.Pcb board needs milling process in the fabrication process, and PCB molding machine will
The unwanted place removal of pcb board, the part left is pcb board final shape.Lathe on the market mostly uses planer-type at present
Frame structure supports in rack the movable body moved along the longitudinal direction to realize the movement of uniaxial (such as Y-axis), crossbeam front mount
A movable body moving in left-right direction realizes the movement of uniaxial (such as X-axis), and carry is vertically again on crossbeam anterior movements body
The small self-movement body of multiple synchronizations of direction movement realizes that machine is realized in the movement of uniaxial (such as Z axis), the mutual cooperation of three axis
The movement of three dimensions of bed.When PCB molding machining, Z axis movable body carries high-speed rotating cutter, X-axis and Y-axis movable body
