Fraisa Thread Milling Cutters - Technical Information

frtmldef.jpg (7752 bytes) In order to prevent profile deformation, the diameter of the milling cutter may amount to a maximum of 2/3 of the female core diameter.
The overmeasure of the bore should be 0.1 to 0.2 mm. Thus, the thread will be milled in a perfect condition.

 

Programming
  1. Position the milling cutter on the thread axis.
  2. Axial immersion to the depth of the thread.
  3. Radial movement to the starting point of the starting loop.
  4. Tangental movement in a circular arc to the rated thread diameter.
  5. Screw interpolation around the lead value P - 400°
  6. Radial retraction along the thread axis.
  7. Axial retraction from the thread.
