Hi everyone,
I bit the bullet and bought a Taig 2019CR last week. I wanted to be able to make brackets and whatnot accurately. I got the steppers on and hooked up and everything moves fine (steppers get fiercely hot though). What a lovely toy!
I made some initial cuts last night on a piece of 1/4" aluminum, using a 3-flute 1/8" end mill. I think my spindle speed was 1650 rpm, and I was cutting .030" deep slots at 4"/min. Seemed to cut through it all just fine, but that doesn't mean I wasn't nervous!
Some things I've read say that I should be feeding faster - like 8"/min, taking a deeper cut (half the cutter diameter), or both. Things were chattering some, but my setup sort of sucked. I'll clamp things better next time.
Am I in the right ballpark here?? Any advice would be greatly appreciated!
Thanks,
Scott
