A twin-head beveling machine for high-precision machining on heads of pipes, comprising two mutually opposite pressers and machining heads with a rotating disk; the pressers are rigidly connected to each other by a central fixed shaft and the heads are mounted so that they can rotate and move axially individually on the central fixed shaft. The machining heads are subjected to the action of hydraulic or pneumatic motors and of axial movement elements, which are activated by a respective hydraulic or pneumatic actuator and produce the axial working advancement of the respective head.
