The invention provides a bamboo cutting-off and deburring integrated machine. The bamboo cutting-off and deburring integrated machine comprises a rack, a guiding-in mechanism, a conveying mechanism, acutting mechanism, a feeding mechanism, a positioning discharging mechanism and deburring mechanisms. The rack is provided with a plurality of conveying carrier rollers. The guiding-in mechanism andthe conveying mechanism are arranged above the conveying carrier rollers. A positioning clamp is arranged between the conveying mechanism and the cutting mechanism. The cutting mechanism is movably arranged on a first guide rail. The feeding mechanism is provided with a plurality of first brackets. The positioning discharging mechanism is provided with a lifting table. The lifting table is provided with a second bracket. A positioning stop block is arranged above the second bracket. The deburring mechanisms are symmetrically arranged on the two sides of the positioning discharging mechanism and provided with grinding wheel assemblies. Automatic feeding is conducted through the conveying mechanism, the cutting mechanism is used for conducting cutting, the deburring mechanisms can conduct grinding work on the cut-off end faces, cutting and deburring can be finished at a time, and the production efficiency is improved.
