System and procedure of clamping/defragmenting parts to a machine tool by means of a reversible adhesive, and use of said reversible adhesive. The system consists of a clamping device (1) provided with an outer surface (3) for contacting the part (2) to be machined; said outer surface (3) being provided with cavities (5) in which the reversible adhesive (21) is housed, which is a mixture of a semi-crystalline thermoplastic material based on aliphatic polyesters with an epoxy resin. The clamping is carried out, proceeding to place the piece to be machined (2) on the outer surface (3) of the clamping device (1) and connect the heating elements (11) until the reversible adhesive (21) reaches approximately the temperature of 120ºc. The deflection is carried out by connecting the heating elements (11) until the reversible adhesive (21) reaches approximately a temperature of 50º c, with the mechanized part (2) being released.

El sistema consta de un dispositivo de sujeción (1) provisto de una superficie exterior (3) de contacto con la pieza (2) a mecanizar; disponiéndose en dicha superficie exterior (3) unas cavidades (5) en las que se aloja el adhesivo reversible (21), que es una mezcla de un material termoplástico semi-cristalino basado en poliésteres alifáticos con una resina epoxi. Se efectúa la sujeción, procediendo a colocar la pieza a mecanizar (2) sobre la superficie exterior (3) del dispositivo de sujeción (1) y conectar los elementos de calentamiento (11) hasta que el adhesivo reversible (21) alcance aproximadamente la temperatura de 120ºC. Se efectúa la desafijación, conectando los elementos de calentamiento (11) hasta que el adhesivo reversible (21) alcance aproximadamente una temperatura de 50°C quedando liberada la pieza mecanizada (2).
