An automatic processing device of a carbon fiber tube includes a polishing device, a washing device, a first drying device, a printing device, a painting device and a second drying device centrally disposed along an identical axis in sequence to form an automatic production line. The polishing device includes feeding mechanisms disposed on two sides of a frame respectively and a positioning-polishing mechanism disposed between the feeding mechanisms. The printing device includes a supporting mechanism and a rolling-printing mechanism mounted on the frame. The disclosure aims at providing an automatic processing device of a carbon fiber tube and a processing method thereof, combining the polishing device, the printing device and the painting device as a whole. Separate processes such as polishing, printing and painting of the conventional carbon fiber tube are integrated to achieve the automatic production in the production line, which can significantly speed up the schedule.

A pressure shoe (1) includes a press surface (2) for directly pressing finishing tape onto a radial circumferential surface (3) of a rotating workpiece section (4) during a finishing process. A plurality of expansion elements (5) is formed in the pressure shoe (1). Each of expansion elements (5) are expandable individually and independently of one another radially while deforming the press surface (2) in a direction of the circumferential surface (3) of the workpiece section (4), so that during the finishing process, the shape of the circumferential surface (3) of the workpiece section can be influenced in a targeted manner via different expansion of the expansion elements (5) distributed over the press surface (2).

A pad conditioner includes a carrier, at least one abrasive element, and a spacer. The carrier includes a surface with an exposed region and a plurality of mounting regions. The abrasive element is disposed on the mounting region of the carrier, and at least one abrasive element has a working surface including a plurality of features each having a distal end. The spacer is disposed on the surface of the carrier and covers at least a portion of the exposed region. The spacer has a first surface and a second surface, wherein the second surface is opposed to the first surface and adjacent to the surface of the carrier. The distance D1 between the distal end of the highest feature of the at least one abrasive element and the surface of the carrier is greater than the distance D2 between the first surface of the spacer and the surface of the carrier.

A corrective grinding device for machining a surface to be ground (2A) of a part of revolution (2) with a main central axis (X2), comprises a base (5) to be fixed on the frame (3), a machining head (10) comprising an abrasive belt (11) which is guided along a belt path (12) so as to be pressed against the surface to be ground (2A) in a first penetration direction (Y10), a belt-driving motor (16) arranged to drive the abrasive belt (11) in motion along the belt path (12), a head movement system (23) for moving the machining head (10) on the base (5) in a second feed direction (X10) along the main central axis (X2). In orthogonal projection in a base plane (P10) defined by the feed direction (X10) and the penetration direction (Y10), the projected surface of the abrasive belt (11) overlaps the projected surface of the stator (17) of the belt-driving motor (16).
