An apparatus (1) for cutting a pipe (2) made of thermoplastic material comprises: cutting means (T) which comprise a tool equipped with a disk (3) rotatabie about an axis (X1) and which are configured to allow a rotary motion of the axis (X1) of the disk (3) about an axis (X2) of the pipe (2) and disk (3) sinking into the pipe (2) in a radial direction; lubricating means (L) for the disk (3), configured to operate on at least one portion (P1.P2) of a face (F1,F2) of the disk (3), for releasing a predetermined quantity of lubricant on it so as to reduce the friction between the disk (3) and the pipe (2) during cutting. |
