I’m seriously considering purchasing a Dominator Pro 4x4 for my CNC machining business. The primary use would be aluminum and plastics, especially larger plate work that I can’t currently fit on my smaller vmc.
For anyone using a Dominator to machine aluminum, I’d really appreciate some real-world feedback.
What kind of cutting parameters have you been able to run successfully in 6061? Mainly interested in:
- Tool diameter
- DOC/WOC
- Feed rate
- Spindle RPM
- Surface finish
- How the machine behaves on longer aluminum jobs
I’m not necessarily looking for crazy material removal rates. Reliability, rigidity, and being able to hold a good finish over larger parts are more important to me.
I’m also particularly interested in the rigidity of the Z-axis/gantry. If anyone has a test indicator and wouldn’t mind doing a quick test, I’d love to know how much movement you see if you indicate against the spindle/Z assembly and apply moderate hand pressure in X, Y, and vertically.
My current router has considerably more Z-axis compliance than I’d like, which is one of the main reasons I’m looking at the Dominator. Actual indicator measurements from a Dominator would be extremely helpful.
I’m considering initially running the machine with the standard/available stepper setup and MASSO, with the possibility of upgrading the motion system later. My main goal right now is to get a rigid 4x4 platform into production quickly.
Any aluminum cutting videos, photos of finished parts, indicator measurements, or real-world experience would be greatly appreciated.
Thanks!
