The combination of pressures exerted on the clamping matrix of the tube, and of the portarutine piece, together with the rise of ascent, descent of the portarulina piece, carries out the realization of the notches, both of regulation and of retention.
La realización de las entallas se realiza por medio de las rulinas junto con unos movimientos verticales, que hacen que dichas rulinas penetren progresivamente dentro del tubo a mecanizar hasta tener la entalla definida. The realization of the notches is carried out by means of the rulinas together with vertical movements, which cause said rulinas to penetrate progressively inside the tube to be machined until the notch is defined.
Las rulinas se encuentran completamente libres dentro del porta rulinas y cada una de eUas son de diferente forma para que poco a poco se vaya dando la forma deseada a la entalla. The rulinas are completely free inside the rulinas holder and each one of them is of different form so that the desired shape is gradually being given to the notch.
Gracias al sistema descrito se evita el proceso de pulido de la superficie del tubo una vez mecanizado (ya que no se generan dichas rebabas). Lo que conlleva a que la estructura tubular no queda tan débil. No se producen fisuras ni perforaciones de la estructura en la zona del mecanizado. Favoreciendo el posterior proceso de recubrimiento.
