ABSTRACT:
A lift case, provided for its possible height adjusting operation, on the front portion side of the apparatus main body provided with electrically driven rotating cutting tools, a plurality of profiling plates provided for their possible lift respectively on the rear portion side from the lift case and the apparatus main body, a profiling plate securing means for fixing the plurality of profiling plates, an urging means for urging the lower edge portions of the profiling plates onto the cutting face of the cut wood under the releasing of the fixing. Release the fixing of the profiling plates to raise the cutting apparatus for working the wood, and a plurality of profiling plates are urged, projected from the lift case and the rear portion side of the apparatus main body. Press the lower edge portions of the profiling plates against the cutting face of the wood as a cutting object in this condition, and the lower edge portions of the plurality of profiling plates is changed in posture so that the lower edge portions of the plurality of profiling plates may be profiled along the cutting face of the cut wood T against the urging force of the urging means even if the cutting face is the convexly curved face, the concavely curved face without limitation that the cutting face is the flat face.
Fix a plurality of profiling plates profiled onto the cutting face by a profiling plate securing means, and the imaginary base face along the cutting face of the cut wood is formed before and after the rotary cutting tools by the lower edge portions of the plurality of profiling plates. Then, adjust the height of the lift case adjusting to the cut rate. The cutting face is finished mechanically by the electrically driven rotary cutting tools even if the cutting face of the cut wood is the flat face, the convexly curved face or the concavely curved face by sliding operation, in the front, rear direction, of the wood work cutting apparatus, namely, sliding operation in the front, rear direction by causing the rotary cutting tools along the cutting face.
