The ball screws start to heat up, so i have to grease everything perfectly before hand. The biggest problem is cause wood starts to chip sometimes as its not perfect material like the plastic or similar. So at the end of the day my philosophy is : Less time i spend on the machine=The better , hence the slower speeds give me perfect finish and i spend less time on the machine. Now if i had ATC i would have pushed jobs using roughing bits, normal and then finishing passes, but as its not the case, i am happy..

So, nope. You don't need a fast machine . You need a precise machine that is free of vibrations and gives you perfect finish.
That's a crazy way to work. So your cutting wood at 1.5mtr/min when you could and should be cutting at 7mtr/min and causing excess tool wear just because you don't want to change the tool one time and do a finish pass. . . .A manual tool change takes 30seconds.!!

I cut aluminium faster than 1500mmm/min.!
