PURPOSE: A wood boring machine is provided to reduce friction, wear, and noise by composing a power transmission unit by composing a power transmission unit through a spline block and a timing belt instead of a gear structure. CONSTITUTION: A wood boring machine comprises a main block(100), operating drill modules(200), a rotational driving unit(400), a power transmission unit(500), and a vertical driving unit. The main block is moved vertically and horizontally by horizontally and vertically transferring modules. A plurality of operation drill module is installed in a main block to be rotated and moved vertically. A drilling tool(230) punching on a wood panel is coupled with the lower portion of the operation drilling module detachably. The rotational driving unit rotates one of the operating drill modules. The power transmission unit links operating drill modules to rotate the plurality of operating drill modules at the same time. The vertical driving unit moves the operating drill modules vertically.
