Really contemplating between HDM vs SO5 PRO 4X4 for strictly aluminum.
I’ve been reading this thread but has been closed.
I really like HDM because it looks and feels beefier than SO5 PRO, but I need the travel envelope to be about 4’X4’ since some of the components can be as as long as 42" long (1X2X .125" AL tubing), the belly pan could be at big as 28"x28"x1/4" thick.
So, for those who has both machines, how much different in cycle time to achieve the same tolerances and surface finish between these SO5 4X4 VS HDM (for aluminum). I looked at other machine like MillRight Power Route 5X5 (Power Route Max | MillRight CNC, LLC) that looks beefier but for an additional 50% cost increase.
This would depend on the tooling and feeds and speeds and whether or no the HDM had an enclosure.
The only people pushing the HDM for maximum material removal rates are those who set up an enclosure/coolant (otherwise you get covered in hot metal chips in short order).
Every employee who has been offered a choice between taking an HDM or an SO5 Pro home has opted for the SO5 Pro.
as regards the finish and material removal rates which an SO5 Pro can achieve:
The ball screws, nuts, rails, and bearing blocks are the same between the two. What makes the HDM more rigid? The linear Z uses HDZ on both too. Is it just smaller size or does is have different X beam design that make the HDM more rigid?
That first video really captured what I’m trying to see. That is actually better MMR than what I’ve been doing with my Tormach 1100S3
