Carbide would may have better information on long term.
I can tell you that after 2 years of running it with an 80mm spindle and max speeds for 30-40 hours a week. At 1/2” doc. I haven’t had any problems.
I don’t like way oil. I use grease. I add some grease to the rails and ball nuts every Sunday.
I put some anti seize on my spindle but threads once a month.
If I mill some aluminum I’ll blow everything clean. I really only use aluminum to make tooling for my self.
Other than that it just runs. Rather boring and dependable.
I can now cut in 2 hours what would take me 13 hours on my S3Xxl with hdz and 80mm spindle. Without constant maintenance
