The saw blade is fitted with a reciprocating bow, fed by a saw frame swinging around a point, with a simple machine structure and small size, but with low efficiency. The motion of the saw blade of the bow saw machine is linear and arc. The arc movement of the saw bow around a point swing a small angle, each saw tooth cut into a larger amount, easy chip removal, higher efficiency, the new bow saw machine mostly use this way.
