The invention relates to a double-saw-blade cutting machine capable of adjusting the cutting angle, which comprises a stander, a fixed working platform, a central shaft and two power assemblies. The power assemblies comprise a rotary working platform. The working platform is supported by the stander. The middle part of the fixed working platform is provided with a circular hole for the rotary working platform to rotate therein. The central shaft is coaxially and vertically arranged below the circular hole. The two power assemblies are rotatablely connected with the central shaft. The power assemblies are respectively and horizontally rotated at certain angle so as to lead saw blades to be fed in a way of swinging up and down and alternately cutting the material on the working platform. The double-saw-blade cutting machine fills the gap that no double-saw-blade cutting device is available for specially adjusting the angle for a long time, thus being major breakthrough of a cutting processing machine.
