Beveling machine

In order to achieve the purpose, the beveling machine comprises at least one set of grinding assembly fixedly arranged on a rack and a pipe fitting supporting platform arranged on the rack in a transversely-moving and sliding mode. Each grinding assembly comprises a grinding wheel used for grinding the end of the pipe fitting and a grinding driving unit used for driving the grinding wheel to rotate in a fixed-axis mode. The pipe fitting supporting platform comprises an angle bottom plate which is connected to the machine frame in a relatively transverse sliding mode, an angle plate which is connected to the angle bottom plate in a relatively rotating mode and a transverse movement driving unit used for driving the angle bottom plate to transversely move. The angle plate rotates relative to the angle bottom plate to be adjusted to a proper angle position in advance, then a to-be-machined pipe fitting is placed on the angle plate, and transverse movement is conducted through the angle bottom plate, so that the
