Hi All,
After 20 yrs away from engineering I am now back and using a CNC Miller (Hurco VM1).
I have speed and feed charts for milling cutters but I am having problems finding them for HSS Drill bits.
What I'm looking for are charts for drill sizes up to about 25-30mm and the recomended speeds and feeds for Mild Steel, 316 stainless and aluminium (304 stainless would be handy as well).
I know that they must be out there on the net somewhere but I am struggling to find them.
Can anyone help, please.
P.S metric charts would be more useful than imperial as that is what I mainly work in, but in desperation I will convert them.
Cheers all
Davor
