Machining tip #251

 


​Hand, machine and shell reamers for cylindrical bore holes are resharpened at the cutting chamfer. The relief angle of the first cut should be 5-8°. It can be reached by changing the height of the support finger. 

With tool grinding machines with a rotating spindle, the support finger has to be adjusted to the height of the centers and has to be rotated to the required relief.
