Looks like a little CNC mill to me..

Now tell me how the heck you picked that? Haha

All i noticed was the NT30 taper, = smaller miller. Hafco or something?

Jay has skillz!

The job has no visible marking out and that hole is way too smooth to have been done by hand. My guess is that's a roughing cut at (what i would do) ~0.3mm less than the finish diameter, followed by a finishing pass, slow the feed down, up the RPM, some coolant to keep the cutter lubed up and the cutter/material cool (also improves the finish 10 fold on aluminium) climb milling to achieve the best finish.

Sorry for the thread highjack there Jay.

Ta, I'm sure we can have some good discussions elsewhere

Yeah sorry Jay! Top work.

I was running the Y axis and John was running the X axis. we where cutting a .5mm. It was a climbing cut so far and the 1st cut we have made so far- it feels good at this point I may not do a finishing pass or I may break out the sand paper or bead blast it for a primo finish

Interesting. I did notice that the hole was slightly eccentric to the slot, but i just figured you were using a different centre. That's very neat if you were doing it by hand i must say. I probably would have set it up in a 4 jaw chuck on the lathe and bored it out if that is the case.

either that or chucked a rotary table on the mill!!!

good work Jay

Almost done with 1 of the throttle body flanges, I think im gona hit the corners up with a belt sander. I'll start the other one this week so I can get the Sri extension done and welded up.

Looks good Jay! What grade is that out of curiousity? I see "65" on it so i'm guessing it's hardened to T651?
