engine dyno controller
Most of them use ball screws for accuracy when converted to CNC instead of the lead screw.
I have a New Bed Mill at work that I am learning the in's and out's of the controller. I am almost convinced I could machine an engine block on it if I had the correct tooling to hold and locate it.
when i say accurate, i mean hobby level for sure. it shows 4 decimal digits but realistically id guess its +- 002 which honestly still leaves my skill level as the limiting factor.
the z axis looks pretty janky on it and it seems like it has a lot of play when using it by hand but when its run by the CNC somehow it stays dead on.
the final tool path for the impeller was a spiral with a 010 stepover so it went up and over each fin like 100 times and the final product looks weird in the pic but is smooth to the touch

Depending on the motors used and the resolution, When the stuff is new and in properly installed it will hold surprisingly accurate results for what it is.... to be deadly accurate though you need a climate controlled shop.... Even the best CNC equipment would be out at least that much if the climate is not controlled properly.
I had a thought on that pump design. At my Previous Job, our equipment used "Gusher" brand pumps. I wonder if super flow purchased parts from them? The did list a CL-CC pump and said it was used for Dyno applications.
