First question - I am in the process of buying a CNC mill and I believe the Haas mini mill series is where I am landing. The standard mini mill has a 6K RPM 7.5 HP spindle. For $10K extra I can get the Super mini mill that has a 10K RPM 15 HP spindle. However, I can spend an extra $4K on upgrading the standard mini mill's spindle to a 10K RPM spindle. Am I missing something here? Why would someone spend $40K on a Super mini mill when you can spend $30K on a standard mini mill and upgrade the spindle to 10K RPM's for just an extra $4K? It looks like the 2 machines have the same basic specs...10 tool changer, same table size, etc.
Second question - I am not sure I need a 10K RPM 15 HP spindle as currently I am only cutting aluminum. However, I do have plans to machine 4140 steel, stainless steel, and perhaps some titanium. Obviously, the more HP I have the better it is to cut these harder materials, but won't the standard mini mill also cut those materials? In addition, my shop does not have 3 phase power, only single phase, so I would need to fix that and I have no idea if I can or what it would cost to do that? Is a 10K RPM 15 HP spindle really needed to cut these harder materials?
Thanks!
