Slitting Saw in 12L14 Steel

[racecraft]

Hi everyone,

I have a hss 3" dia, 32 teeth, .125" thick slitting saw. The saw is staggered tooth and had side-milling on every other flute.

I am going to cut a slot in a part that is made from 12L14 steel with a flood of coolant.

The slot is about 1" DOC, at the deepest, on a 1.5625" radius. Therefore the cut is not very long, maybe 1.5" long.

I am just wondering what i should be running for feeds and speeds? Also climb or conventional cut? Multiple passes or full depth?

Thanks for the help in advance. Very much appreciated!

100 sfm is very conservative and safe, 130 sfm if you plan to stay on the lower side of the cutting depth. That said, I'd go with 130 sfm and 4 passes or .250 radial depth per pass. Go .0012-.0015 inch/tooth... again, use the lower side for deeper radial, higher side for lighter radial. The chips should be no darker than a light straw color. 12L is a nice cutting material, pretty easy on saws... unlike many other materials.

edit: Conventional milling

Best regards,
Chuck

Full depth of cut - one pass, flood coolant, 100 SFM. 12L14 cuts like butter. I love it.

Sounds good guys. When i get to those parts in the next couple of days, ill be sure to give your advice a try!

Thanks!
