rung fu clone RF-45 ZX45 cnc conversion

jumps4 said:
I finished wiring the 4th axis and calibrating it. I made a short video of it simulating cutting a 10 tooth gear with the axis facing you to see it better this is a demo vid and would not do anything but break a cutter lol
well: my mill is done and i guess this thread is done
the only other thing i may do is mount the head on an 10" rotary table for easy angle settings and tramming but that will probably stay manual...
you never know
to everyone who was interested
thank you

Looks like that imaginary gear had big teeth, maybe a rear axle ring gear?

Seriously though, I think you've been living the dream of some of those who have been following this thread.

At some time in the future I hope to do the same with a larger mill, but for the moment I'm slowly CNCing my little Sieg X1.

Great thread Steve but I don't think you're quite ready to close it yet.
Personally I'd like to see some of the real projects you make with it and perhaps some video of it while it's doing it. :thumbzup:
 
ok here are 3 videos of it making the z axis parts for my 9x20 lathe cnc conversion
i will be able to move a lot faster when i get my high speed spindle set up.

How are you going to do the high speed spindle? Speeder? Additional bolt-on spindle?

A faster spindle is something that I would love on my machine, so I am curious.
 
I have not decided yet really, i'm thinking about 3 different types
a water cooled 1.5 kw 3 phase with vfd for $245 er16
a side mount driven off my original spindle er20
a center mount driven off my original spindle er20
I have put it on the back burner for now until i get the lathe done
but i'd like to get to at least 8000 rpm

Great job Steve this has been a good threat, Even through I don't want to CNC anything I enjoyed watching your progress and movies.

Steve,

What size rotary table is that? And the stepper ... what is the torque?

Thanks,
Arvid
 
Steve, I'm curious how hard you would rate this conversion?

I just completed building a CRP-4848 CNC router table. I have no prior experience with machining, in fact the only tools I had to start with were hand tools and a drill press. I have electronics and computer experience being an amateur radio operator and a systems admin/software developer for 25 years. I went on to buy the basic tools I thought I needed - radial saw, grinder, calibration tools, etc. I found the CRP-4848 pretty easy to build. I spec'd out the PMDX boards, the ESS controller, and all the electrical for the shop and the 220V spindle/VFD myself. It was challenging because I hadn't done it before, but it worked pretty much the first time I powered it up.

How would that compare to converting the ZX45 to CNC?

The biggest challenge I see is that most folks tackling conversions already have at least a manual mill or lathe. They can cut the parts they need for a conversion like this. The best I can do is cut aluminum, not steel. Once I had a mill, then I would expect I could pretty much tackle any project. I guess a lathe would be next :) I see myself being very cash poor for the next few years.
