The invention provides a batten edge cutting machine. Two edge cutting machine are arranged on the top of a rack and a guide rail on the left side, clamping parts are arranged in the middle of the top of the rack and the lower portion of the left side, a sliding rod allowing materials to flow is arranged on the rack and is of an L-shaped structure, the upper portion of the sliding rod penetrates the clamping part on the upper portion of the rack to be connected to a feeding platform on the right side of the rack, and the lower end of the left side of the sliding rod is connected to the clamping part arranged on the left side of the rack; steering mechanism are arranged at the transverse and vertical corners of the sliding rod; and the materials enter the sliding rod from the feeding platform to achieve feeding and are subject to clamping and edge cutting in the clamping parts on the top and the left side, and direction changes are achieved at the corners on the top and the left side through the steering mechanism. By means of the full-automatic mechanical treatment manner, the two ends of a direction batten are machined, a square step column which is stable in quality, even in position and stable in size is formed, and the working efficiency is greatly improved while the quality of the finished product is guaranteed.
