Hi Guys,
Not real happy with cut quality on soft / hard woods and was wondering about RPM's. I've gotten into the habbit of using MAX rpm 18000 of my spindle (HSD 2.25 HP) as a constant, keying in the desired chip and away we go, then decreasing / increasing feedrate as needed. Should I be using different RPM's for different bits. Using the starter bit collection and their is no RPM other than 18000 that I can see in any documentation, so I'm asking the pro's. What RPM works best as a rule of thumb and especially on V Bits and engraving bits as well.
Also...I know the books say +/- .005" for positioning on a standard...getting +/- .020". Is this the best under load or can I improve this...does RPM effect this.
Thanks
Nick C.
