Generally, composite pipes are lighter and durable than metal pipes, and have a variety of advantages over conventional metal pipes. Such a composite material pipe is manufactured by impregnating glass fiber, carbon fiber, aramid fiber, etc. with a resin, and then winding it to form a shape and curing at room temperature or high temperature.

On the other hand, the composite pipe described above is made by winding a fiber material impregnated in a resin as described above, so that its surface is rough so that a smooth surface can be obtained through a surface polishing process after curing.

KOKAI Publication No. 2003-0051133 discloses a surface grinding apparatus for grinding a surface of a pipe, which comprises a frame, a grinder provided with a grinding stone, a support mounted on the frame for moving the workpiece, , And a buffer means.

However, the conventional pipe surface grinding apparatus described above has a problem in that it is difficult to polish a composite pipe having a precise surface such as a rough surface, because the surface of the composite pipe is hardened when the composite pipe is cured by winding the fiber material.
