I'd pay 10,000 for that. Excellent work!

You are right , there are 4 pieces of aluminum extrusion , 80mm x 80mm ,
heavy , made by ITEM . They are hold together by those aluminum plates ,
( 1 in front , 2 at sides , 1 on top ) wich are bolted to each other too...
Plus , the extrusions are conected with the base ... There are some pics of
the structure around here , take a look there ...
First test ... X and Y axis movement at 3600mm/min .
It can go to 6000 , but travels are small ( 280mm x 480mm )
so there is no need ...
Very Nice.
Keith.
Thanks ... I apreciate feedback .
hope to make Z axis test in few days ( motor and driver already
arrived , have to go to post office to pick it up ... )
After testing everything , I will break down the entire machine ,
reassembly using ALL the bolts and nuts , align the axis , and make the
cutting tests ( carbide endmill / aluminum ) . Only then will see the true
performance of the mill ...
more movies will be posted shortly ...
I don't think I could ever get tired at looking at pics of the beaut mill your making Katran! Simply awesome job mate! Puts a lot of other efforts to shame.
cheers,
Ian
It's rumoured that everytime someone buys a TB6560 based board, an engineer cries!
You have certainly earned it. A very impressive machine, one can not complement it enough. Truly a thing of beauty.

You have an interesting design in this machine, I'm sure many of us are waiting for the final build.After testing everything , I will break down the entire machine ,

Inspiration for the rest of us.more movies will be posted shortly ...
Wonderful work as everyone else has eluded to.
To say your shop was ever a mess is laughable. What are you making medical equipment? Electronics and therefore require a clean room? I bet you can't sleep if you leave a tool on the table. Great work.
Hoss was asked to do a spindle deflection test of some form (its validity has been questioned but for simpletons like me it made sense) where he used a fish scale attached to the spindle, he applied a specific load and measured the deflection. He was asked because people were trying to compare the X3 to a G0704. I would like to see a similar test in your machine, just for a reference.
No matter how many times I have modified this post it keeps running the paragraphs as a single sentence! It shows as paragraphs til I hit save. Tapatalk is POS most of the time. The price is right though.
A lazy man does it twice.
O.K ..uh... first of all , thank you . It's nice to see that my work is apreciated
I like building cnc machines , but I don't actualy use them ... much .
I am not trying to make a living out of this , is just a good way to spend
my free time ...
I spent a lot of time and money to bring the shop as it is now ... but this
shop is my only " island of solitude " , a place where I can do my thing
in peace and quiet ... You have no idea how stressful is my job ( I am
an air trafic controoller ) , so I need something to keep me sane ...
Deflection test ? You lost me there brother ... Why ? How?
What do you mean by " doing it correctly " ?
B Rad and Bam have both been helpful at times even if they might be the same person. Though the validity of the test might be in question, if the test is done with similar parameters (spindle nose 5" off the table etc) I can make a conclusion of some form. Seems like somene told me a while ago that my fan idea wouldnt work. Hoss did me a favor because I asked him to, and he was prepared with all the necessary tooling and knowledge. IMO it worked. Now I am asking Katran to do a similar test. If you have a better way by all means let us know but until then I still want a test that has been applied to other machines the same way.
Uh ... so , what is the big fuss with this test ? If it is that important , I will do it ...no problem .
It will absolutely deflect in some way , no question about it ... Maybe the column , or the spindle head ...
I don't give a rat's ass about the actual result , does not matter to me .
i said it once, and i say it again... damn gorgeous machine... very inspiring!
makes me wanna go take a trip to romania to see it in person...

Katran,
Your build is great. The results of the requested tests are more out of curiousity. Having seen it done on a few machines I am familiar with, it would be interesting to see the differences. I cant imagine the test creating any issues on the machine, taking much time or special equipment. Just a few minutes of your time and a little patience. I learn so much more by seeing and doing than reading and trying to comprehend formulas, loads and stresses. I wont be offended either way.
LOL I have to agree that this fascination with a deflection test is a bit weird. If the man doesn't want to waste what little free time he has with minutia such as a "simple deflection test" so be it. Besides, with that beast of a spindle, anything that gets in its way will be decimated long before any "deflection" shows up!
So if Katran is kind enough to take away from his leisure to humor people with a probably insignificant [to him at least] test then so be it.
Initial build/mokup it's about done ... All axis perform well , no glitches ...yet .
I still need to organize cables , find a better spot for the computer ...
The big problem now is protection . I need to cover the rails and screws
with some sort of way covers ... Any hints ?
Also , a new movie ... I'm no film maker , so please be gentle ...
P.S .
third part of movie shows rapids at 6000mm/min . I think I can go
to 8000 , but I'm afraid ...
P.P.S .
Can anyone explain to me how to make that deflection test ? Thanks .
................
Katran, Hoss and Xnaron both have them performing thee test on their respective threads and machines. Basically applying a side load to the spindle with a ratchet strap and using a fish scale to measure the load being applied.
Regardless of any of the results of the above test. That machine is beautiful. Well thought out and executed. Take a bow!
I'm stuck 100km away from workshop for the next few days , I got bored ...
I made some sketches for a cnc lathe that I wish to build ... I was thinking
of using a BT30 cartridge from Tormach as a spindle ... Is that a good idea ?
Maybe some gang tooling ? Turret system seems to be a bit complicated ...
Here are some pics ...
P.S. Design is " stolen " from existing topic ...here on cnczone . Hope that
the user will not be upset by that ...
............
As i said, touché man, awesome job! As for the lathe thing, the gang tooling system is the easier way but, seen your capabilities, i encourage you to go for the turret style.
Anyway, have you considered some way to protect the linear ways/ballscrew? IMHO, a nice sheetmetal covers would be the final touch to this masterpiece!
Something like this, not the best but i think you get the idea http://www.cnczone.com/forums/vertic...ml#post1034230
katran,
The only thing I don't like is the linear rails being exposed. I would use something like a u shaped mount to place the linear rails and trucks underneath.
I had a question about your nice looking mill. How would you tram the mill? I'm asking because of the number of extrusions you use for the vertical or z-axis. Do you have any dimensioned drawings of the mill?
Thanks,
Paul
