   <EMI ID = 1.1>

  
The present invention relates to a head

at several speeds, in a varied or continuous manner.

  
 <EMI ID = 3.1>

materials to be machined ......

  
The description below, with reference to the drawing

  
appended, will show the characters of the tool head

 <EMI ID = 11.1>

This forms a nut on a screw 5 which passes through it and the angular displacement of which ensures the radial displacement of the slide, said screw itself being movable in rotation in

The external part of the head, 7, of this screw is graduated in tenths of the pitch of the screw thread.

As a result of this assembly, the elastic strips 15,

In the latter case, the buttons: exert an axial thrust on the free end of the strip which corresponds to them. which lowers said blade to a level where it will be encountered by the pusher 10 when the latter, which accompanies the rotation of the tool holder head, will pass over the radius of the free end of the lowered blade. A <EMI ID = 20.1> .pulse from top to bottom, .and the pawl coming into contact with a tooth of the wheel at. ratchets, will print it an angular displacement <EMI ID = 21.1>
