HDU Feed Rates Chart

How To Machining

Question of the day:

Are there any charts out there showing feed rates, plunge rates, RPM, depth per pass for HDU?

I’ve pushed it pretty fast and still feel pretty safe (quality doesn’t seem to be affected, zero heat on the bits).

Using:

  • 1/4" shank 1/8" down cut 2 flute end mill
  • 1/4" shank 30° V groove

Max depth for both is 5mm.

As I’ve progressed through an understanding of this, HDU feed speeds seem to max out the Pro 5’s max feed speed limits. More to come as I understand this better!
