I am in the process or researching for a CNC router machine. After a month of research I have concluded the best option for me that gives me the best options and performance at a price I can afford is the Avid Pro in a 4x10 size that will allow me to have a rotary axis, vertical milling capability along with a full 4x8 platform to cut full sheets of material. Adding a vacuum bed will bring my total cost to around 22k. This includes a 8.7 hp spindle and 5 Nema 32 stepper motors. After making my choices for upgrades I discovered the 8.7 spindle only delivers 6.4 hp on single phase 220 volts. I don’t have 3 phase to my house only single phase 220 and it’s cost prohibitive to run 3 phase to my shop. So I am paying an additional 2k for the bigger motor and losing almost 2.5 hp. My question is do you know of any spindles that will fit the AVID pro machine and run on single phase 220 volts power in the 5 to 6 hp range in the 2 to 3k price range?
