i have the same machine with the 5" z axis. i only tried to cut aluminum with it once and decided to never do that again. the x-axis probably needs to get upgraded to supported rails somehow. i enlisted the help of a local machine shop to make a new 1/8" collet for my PC 7310 and it cost $80. but in the real world i guess that's cheap.
i guess a good analogy would be if you held two straws together parallel. the closer they are the more flex.
btw what size and shape bit are you using, rpm?
