Depends on your application, If you are running lots of aluminum, and soft materials, the fadal is "OK " but the standard answer I got whenever I had tooling problems with my 4020 was, the machine isn't beefy enough, of coarse the majority of my material was 4340 aircraft super clean ..36-42 HRC . the main problem we had was slippage due to blown belvile seal in the top end. The coolant mixture PH really needs to be monitored for all thru- spindle machines or the result can be costly to repair. The haas is also a great machine for most applications, however if you are used to the "neat" built in can-cycles of the fadal, it is going to take some conversion of your programs to run them in the other machines.
