Capability of VN22L--How big a cut?

[Nmbmxer]

You also need to consider chip thinning when you taking such light cuts. You'll get .002/tooth, but only if the cutter were buried to the centerline.

I run my horizontal mill alot and have found that going slow and taking big cuts is much more productive than trying to run fast.

I've found this to be true in all manual milling that I've done so far.
Slow surface speed, very high feed, then as large a DOC as you can take before the rigidity of the machine or setup starts getting inadequate.
