PROBLEM TO BE SOLVED: To provide a lumber cutting device for easily performing the chamfer processing of an edge of a lumber cutting plane. SOLUTION: A lumber cutting device 100 for cutting a lumber 500 to be processed by a circular saw 31 attached to a rotating circular saw shaft 3. The chamfering of the upper edge is performed by abutting a rotating upper chamfering cutter 11 along the cutting section on an upper plane of the lumber 500 cut by the circular saw 31 thereby forming a V-shape cross-sectional concave groove X, and chamfering an upper edge of a plane cut by the circular saw 31 an upper chamfering shaft 1. The chamfering of the lower edge is performed by abutting a rotating lower chamfering cutter 21 along the cutting section on a lower plane of the lumber 500 cut by the circular saw 31 thereby forming a V-shape cross-sectional concave groove Y, and chamfering a lower edge of the plane cut by the circular saw 31 with a lower chamfering shaft 2.
