316..tough stuff and stringy chips. Beautiful plus you timed the operations. I used to work in a plant that did stuff like this in addition to pressure vessel fabrication. They had a huge CNC burn table with oxy and plasma. Trepanning was not used as it took too long.

@@keithjurena9319 ya,a cnc cutting table would be nice, not at this place for a few years yet I’ll bet……we’re very “traditional” (stuck in the past). Thanks for the comment.

@@OgiveBC I hear you! That CNC burn table started out as an optical eye system which traced over drawings to make the cuts. It was a pantograph type system, I forget the scale

Get a roughing carbide endmill. Guhring makes a series with Firex coating that I really like. Then just have at least air blast on it, and do your slots in incremental step downs, 50-100 thou at a time depending on material and diameter. Once it's all roughed out, come back with a finishing endmill to make it nice and bring it to size.

Very interesting, I’ll look into that for sure. Always like trying something different. Hopefully I’ll try it soon and can make a video about it. Thanks for the info.

As far as deep slotting goes we pretty much run whatever is handy, 2,3,4 flute etc. I find you have to run 4 flute shallower otherwise they blow up recutting chips, you can definitely tell a difference running two flute. I would run a fine tooth roughing end mill with air or coolant blast to clear chips and finish with a standard end mill. Since I started running CNC I run 4 flute full depth with a 10% step over & two flute for slotting up to 1/2D. That is pretty much max for full dia slotting for any endmill. I hate 316.

@@pvtimberfaller thanks for the info and ideas. I haven’t tried just the air blast in a long time, I should try that again. Also I haven’t spent enough time looking at roughing end mills in the catalog. Thanks again for the tips.
