摘要： A clamping unit (1) for a laser cutting machine (1000) for cutting a tubular component (C) comprises: a clamping chuck (10), configured for rotating about a respective axis of rotation (A1) and for entraining the tubular component (C) in rotation; a rotary actuator (11), configured for setting the clamping chuck (10) in rotation; a plurality of clamping tools (13), each including a first end, connected to the clamping chuck (10), and a second, free end, opposite the first end along an axial direction (A) parallel to the axis of rotation (A1). The tools of said plurality (13) are movable towards and away from each other along a radial direction (R) perpendicular to the axis of rotation (A1) between a respective rest position (PR), in which the tool (13) is radially spaced from the axis of rotation (A1) by a first distance (D1, D1'), and a working position (PL), in which the tool (13) engages the tubular component (C) and is spaced from the axis of rotation (A1) by a second distance (D2, D2'), smaller than the first distance (D1, D1'). The clamping unit comprises a clamping actuator (14), configured for moving said plurality of tools (13) between the rest position (PR) and the working position (PL). Each tool (13) is configured for applying a clamping force (FP) on the tubular component (C) including at least one component along the axial direction (A), having a clamping sense (V1) towards the inside of the clamping chuck (10).
