rung fu clone RF-45 ZX45 cnc conversion

[jumps4]

I ordered a rotary table this morning to convert to cnc for my 4th axis from wholesale tools it was $350 including shipping and tax.
it is 6" and i have a new 4 jaw chuck to fit it and i'll probably build a trunion table.
i already have the stepper motor and the power supply and controller were installed.
I guess i will be adding more to this thread sooner than i expected

More toys, especially at that great price, has to be a good thing! )

Question: As you're setting this up as a CNC fourth axis, won't that make the included index plates redundant?

i will not need the plates for this setup but i have other rotary tables i can use them on. for $350 to get just the tailstock with it was a deal so i have more parts for future projects. if i ever build anything besides tools it will be an epic moment.

Ok, another question, and hopefully not reopening an old can of worms, but with the 4th axis rotab having a chuck installed, mounted vertically on the mill table and holding a work piece between the chuck and the tailstock, wouldn't it be possible to cut virtually size and type of gear including worms, with ease (assuming the correct programming is used)?

yes after making a cutter with the correct shape for the tooth needed

Steve,

I'm really interested to see your progress on 4th axis. I have been thinking about adding one for myself, but my main concern has been backlash. I am probably over-thinking it like I do everything else.

Thats quite the project you have going on.
Whats the cost of a project in parts/components for a set up like yours? Is all that wiring as scary as it looks?:thinking:
Ill be following your project as it progress,s

:thumbsup:

yesterday the total was about $4200.00 today it is $4550 with the 4th axis
the wiring isnt really that bad it is for the most part there are four circuits one for each axis in this one 3 are exactly alike

That was really fascinating to watch, thank you.

the video was good thanks
the backlash can be adjusted out of the gears but to get a nice tight fit with no backlash and binding the gears have to be polished. once polished they do not bind when tightly meshed. on a smaller one i used tooth paste to polish the gears and let them run together on the drill press at the slowest speed for about an hour. adjusting them tighter from time to time. they mated perfectly. a good washing and light oil and they were good. the rotary tables have a backlash adjustment.
