I have a few question on how to get the cleanest cut with a slitting saw on the inside of my hole. The pic included isn't the part, just a quick test, but will show you the burrs left on the inside and out.
A rail is going to be clamped in this hole and has a pretty tight tolerance. The smoothest cut possible is what I need (at least on the inside). There will be 7 of these parts in my vise to be cut in one pass after drill/tap. 6061-T6 AL, the saw I'm using is
Carbide Slitting Saw
2.0" dia
.062" thick
22.9 IPM
580 rpms
@ 0.45" woc (stock to be removed)
The cut went great with very little problems on my test but my material to be remove was 0.18" woc. Do you think these same settings at 0.320" woc it would go as smooth or split it up in two passes ?
Last was which is the biggest problem I have at the moment is which way to feed the saw in my part/clamp leaving my reamed hole without any deburring needed ?
The cut in the pictures was CCW climb cut from the left going right. I'm thinking if I switched the feed & spindle direction to cut from the right going left in CW, it might help the burring. Starting cut on the inside of the hole first, then exiting thru to the outside of my part. Any ideas ?
Or would the little green triangles in my tumbler get the job done ?
