ABSTRACT:
A wood tapping machine includes a cutting device formed on a machine body which has a tapping rod extending horizontally from the cutting device. A guiding path is formed on the machine body and has a toolrest which is disposed slidably thereon. The toolrest includes a base member and a cylindrical casing that has two arms extending therefrom and connected pivotally to the base member. A driving rod connects the base member and the cylindrical casing and maintains the cylindrical casing parallel to the tapping rod of the cutting device. The cylindrical casing can swing relative to the base member when the driving rod rotates about its axis. A main shaft is threadedly and rotatably disposed through the cylindrical casing. The main shaft has a chuck assembly at one end and a rotation wheel at another end thereof.
