ABSTRACT:
A rotary cutter of a wood planing machine includes: a rotary shaft that has alternately disposed fan-shaped vanes and fan-shaped grooves; and blades secured respectively to the fan-shaped vanes. Each of the fan-shaped vanes has a leading face and a trailing face. Each of the blades is attached securedly to the trailing face of the respective fan-shaped vane. The leading face of each of the fan-shaped vanes and the trailing face of an adjacent one of the fan-shaped vanes converge toward a center portion of the rotary shaft so as to define a respective one of the fan-shaped grooves, and cooperatively define an angle therebetween. The angle is greater than 60 degrees and less than 120 degrees.
