Borrisl, poppabear10, acerocket and the rest of the Guys lend me your ears,
fella's need a little wisdom, or maybe a good bit of gut feel. The situation is this. I bought the cnc shopmaster a little over a year ago to prototype a militaryweapon accessory. Now, I doing limited production runs. I have upgraded the Mill motor to a 2hp motor(3450 rpm) and am able to cut 6061 .060 to .070 deep (full width cuts) at 18 ipm (4 flute cobolt mill 1750rmp), but I can see evidence of the machine flexing as I cut 1/2" wide full with slots about 2" deep.
Let me put my web site and you can tell what I'm doing.
http://www.safestshot.com. I realize that I may be working the machine a little harder than what it is intended or maybe not. Any way to make the mill a little more ridgid, or better feed rate speed feed suggestions (with the higher speed motor) higher spindle rate are possible, but not sure what the pully and drive bearnings will tollerate.
The answer maybe to be content with cutting less and slower, but now it's time for me to be silent where the wize voices can be heard.
Speak to me old great ones (a little humor never hurts)
Thanks for your input!
