par un système hydraulique, 

  
Par rapport aux machines connues, cette Machine présente les principaux avantages suivants:
- une plus grande rapidité de coupe, car deux scies sont en cours do travail et n'attaquent la barre que sur une faible portion de leur circonférence; leur pénétra":

  
 <EMI ID=45.1>  .. l'emploi d'outils moine coûteux, car la soie  <EMI ID=46.1>

metals, more particularly metals in bars ", this

  
 <EMI ID = 3.1>
- cut-off using a sole mill passing through the bar or the tube
- parting with a lathe with a bleeding tool parting with a bleeding tool rotating around the part to be cut. <EMI ID = 4.1>

  
or especially if the bar is not absolutely straight, it is also necessary to provide a great power to cause the rotation of these parts, sometimes very heavy.

  
 <EMI ID = 5.1>

  
given above because the machine tools based on this principle cut metal only at the length of a radius and no longer a diameter. However, the length of the tools'

 <EMI ID = 7.1>

  
causes the bar to pass through its center, in order to obtain normal cutting speeds, it is compulsory to rotate

  
 <EMI ID = 8.1> <EMI ID = 9.1>

  
the invention is remarkable in particular in that it comprises at least one and preferably several cutting tools

  
 <EMI ID = 10.1>

  
Other characteristics will appear in the description which follows,

- the vice can be placed outside the casing, beyond the plane of the tools, in this case, the vice is fixed on the base of the machine;
- the speed reduction device resulting in <EMI ID = 44.1>

  
by a hydraulic system,

  
Compared to known machines, this Machine has the following main advantages:
- greater cutting speed, because two saws are working and attack the bar only on a small portion of their circumference; penetrated them ":

  
 <EMI ID = 45.1> .. the use of expensive monk tools, because the tang <EMI ID = 46.1>
