I'm working on a job that needs a fairly decent finish pass ( it's a mold for a lead fish weight )
I'm attaching a photo of the piece to help explain it better.
Basically it has two cutouts that are about 1 1/4" diameter and about 20 inches long.
Currently I'm using a 1/4" ball tip end mill for the finish pass.
I'm doing a .01" step over
It's producing a really nice finished product, but I'm trying to get the milling time down on this.
Currently Its taking about an hour to do the finish pass on each side of the mold. ( Each side of the mold has 2 of these cutouts )
So the question is.... is there a more efficient tool I should be using?
Here are some of my other settings for the 4 flute ball end mill
RPM: 9167
Surface Speed: 600
Cutting Feed Rate: 95
Feed Per Tooth : .0026
My maximum RPM on my machine is 10,000
Thank You...
