Very nice work

Re: CAT330D-L full hydraulic
 

Looks really good, keep it coming!!!

Re: CAT330D-L full hydraulic
 

Amazing!

Re: CAT330D-L full hydraulic
 

Great Clean Super Build......I will follow this job for sure. Where on the earth are you located ?

Re: CAT330D-L full hydraulic
 

WOW! Are you a professional CNC operator? Or just have one for personal projects?
Also who makes those hydraulic fittings?

Re: CAT330D-L full hydraulic
 

Thanks a lot to everyone...
@Bo Wallen: i'm from Florence.
@avel: i have been a manual/CNC machinist (mill and lathe etc.) for several years and begin to work with a lathe for hobby when i was 13 thanks to my father's mini lathe. But the work you see in photos is made by my personal manual lathe and mill (more heavy machines). The hydraulic fittings are made by SMC corporation in Japan. They sell all over the world and in the USA is more simple to find and buy it than in Europe. In Italy instead is a big problem... like for everything! Price is crazy!
You can buy it from www.smcpneumatics.com or even on Amazon. Search for "smc miniature fittings M series".

A few minutes and i'll send other photos...

See you soon!

Goodbye!

Re: CAT330D-L full hydraulic
 

OK thanks, and keep the pictures coming.

Re: CAT330D-L full hydraulic
 

Impressive!
How does the wheel motor work?

Kerst

Re: CAT330D-L full hydraulic
 

Yes I'm interested it that too, next time you have the wheel apart so us some pics of the way the hydraulics work. Very impressive build so far!

Re: CAT330D-L full hydraulic
 

very impressive build

Re: CAT330D-L full hydraulic
 

very nice work

Re: CAT330D-L full hydraulic
 

Great job:)
I'm also very interested of how you made the hydraulic motor, more details and video please.

Re: CAT330D-L full hydraulic
 

Hi everyone, thanks a lot.
The motor is of the orbital type and it has 7.8 cubic centimeters of capacity. This is the first attempt to build it and the torque is too low even if in general it works well. I have now to receive the special profiled rotor-stator coupling from an external laboratory that work with CNC mill and reassemble the motor for the tests.
Then i make a video....

Re: CAT330D-L full hydraulic
 

Thanks thuangs.

In the meantime some other photos...

Beautiful!

Re: CAT330D-L full hydraulic
 

Very nice machine work.

You are displaying great patience and bravery for making the hydraulic rotary manifold and making hydraulic motors for the drives.

Re: CAT330D-L full hydraulic
 

gorgeous! trully a work of art!
