We used to do the same jobs on both Haas and Fadals. X Y Z rigidity seemed almost identical. We all used to agree that the old 710 ipm haas with the 22 horse gearbox was the toughest machine we had (we had only one with the 22 horse). This in a shop with two 4020's, a 6030, vf-8, and four vf-2's. So before you Mazak trolls laugh, keep in mind that is what we compared them to.
What is your experience comparing the 4020 to the Haas makingchips? |
I use the 40x20x28 for mold work I use the VF4 for live 5 axis work. We just bought the VF4 to replace the old Fadal 5 axis we had. We got the linear scales on the HAAS so it is very accurate compared to the old Fadal.
The last place I worked had 3 Fadal's 2 Haas's and a Makino A55. We made aerospace parts mostly titanium and stainless, during heavy cutting the Fadal would hold true all day long with no tool chatter the HAAS you would have to take lighter cuts to get the same results with no tool chatter due to the rigidity. They both have their pros and cons for instance the Fadals tools would often get stuck in the spindle when under heavy load for long periods of time. The new HAAS can change a tool in 1.2 seconds.
