<p>A method for double-driving force grooving and cutting wherein each driving force drives a cutting tool for grooving or cutting, and wherein the cutting tools rotate in opposing directions. A multifunction grooving machine made according to said method includes a machine body (1), a case (2), handles (3), power systems (4), cutting tools (5), elevating mechanisms (6), speed change mechanisms (7) and a power switch. The multifunction grooving machine has two independent power systems (4) which are arranged symmetrically relative to the cutting central line. Each power system (4) drives one cutting tool, and the two cutting tools rotate in opposing directions. The grooving machine can form grooves in marble, concrete structures, and so on.</p> |
