View Full Version : Using re-grind tools with true-mill

08-30-2007, 11:27 AM
Has anyone else ran into a problem on using re-grind endmills on truemill operations ? I know that using a smaller diameter tool has to effect the engagment angle but I wouldnt think that being only .020" or so undersize would change it enough to affect tool life a great deal. If anyone has had this problem could you let me know a solution other than re-posting with the re-grinds diameter.

also take into consideration if you have a coated endmill reground and its not re-coated, that will affect tool life also..

We actually have had the tools re-coated, I had our iscar rep in last night and he suggested taking a full depth of cut of 1.650" (using a fullsize e/m) so we will not only be using just the bottom half of the e/m and it seem to give us much better tool life and decreases cycle time.

ok, just checking, and glad to hear you were able to get better tool life and decrease the cycle time.. its always great when that happens ;)
