Same as all of the other VHF mills flying around. I personally like my VHF/EZMILL very much and don't find a need for a 5th axis. I don't know if Wielands comes with the OEM CAM but mine did and I literally spend 5-10 minutes loading an entire disc, hit START, and the mill starts milling right away. No calculations, no processing, nothing. Load and GO. I'm glad there isn't a full/robust CAM suite included because this works and it's FAST.
As long as you keep it clean, change the burs when they are done and keep the spindle maintained (a once a week cleaning) then you should have no issues. Been running strong for a year.
