@2Cool585: Thanks for your feedback but as far as I can see it is a "passive" device - I need to be able to mount it on my CNC mill and then run it over the relevant surfaces - yet with a low...

Hi All,
I have a question that hopefully is not too complicated - and which I hope one of you may help give a bit of advice about ...
As it is I am currently working with quite small &...
Hi Mactec54 ...
& thanks for (maybe ;)) being able to calculate V/H values for the VFD/spindle combination I have ...
As to the VFD I have attached a picture of the product label to this...
@mactec54:
Hi .. if you have a link/a copy of the additional settings I'd be very interested in seeing them. I think the spindle (normally) works very well but if it can be further optimized...
@mactec54:
Hi ... & thank you also for your feedback :) As to your question about the settings of my VFD I actually think that I am using the settings you have suggested here:

Hi Andrew,
& thanks for your feedback! As it is I tried to power up the motor again this morning and much to my surprise after 1-2 minutes these noisy sounds disappeared again ???? ... So at...
Hi all,
Well, this certainly has not been the best of days :( ... I was slowly milling into a steel bolt/a cast iron base with my 2.2 kW spindle and 2.2 kW Huanyang VFD, and I seem to have...
Hi Craig,
Well, you have already told me about this but interesting to get some more details ... Good luck with the project ;)
Now I know that you are doing more things with your mill but...
Hi Craig & Gerry,
Thanks for your replies ... As it is it is not acceptable with the oil leak - and given the small sizes I mill on my CNC it could be a challenge to seal all air leaks. So I...
Hi all,
Just read and thought about the discussion you have on whether or not a a tank makes a difference in terms of "saving vacuum". I think it may be related to the gas equation P*V=n*R*T ......
Hi all,
& thanks so much for your feedbacks ;) ... Reading your replies makes me wonder if I then bought the wrong pump - and then again, no, I probably didn't because the budget is tight and...
Hi all,
I've recently bought a small ½ HP rotary vane type vacuum pump which by specification should be capable of 4.5 CFM of air flow and generating an ultimate vacuum of 0.3 Pascal.
I use...
Hi all,
I just want to post a brief follow-up to this thread ... As it is yesterday I had to mill a very small copper plate where I was unable to use the exhaust/dust collector I have made. This...
Thanks again mactec54 ...
... I sort of guessed this while looking at the video. Actually, quite fascinating that a relatively simple setup like this can produce such a result ...

Hi mactec54,
Thanks a lot for your feedback! As it is it has made me check out some options this morning and it seems to be the best solution for my purposes. One question, though: In this video -...
Hmmm ... might this be a challenge ... ? Still hope some of you have experience with this ;)

Hi All,
I am having a bit of a challenge that I hope one of you here may be able to help with - I'd appreciate your assistance ;)
As it is I need to make a copper plate with a thickness of 1.5...
Hi Craig,
Thanks!
And, yes, you did mention this - but to my memory you pointed out that a solid bed would be "hugely superior" only after I had bought the cast iron bars (which I had...
Hi all,
It has been a while ... hope you are well out there in the world :)
As it is I have now completed my CNC build - except for a few things like painting the supporting table and...
Thanks routalot ;) ... It actually works very well ... I think one reason why is that when the spindle nut rotates it sort of "whirls up" the cutter shavings which then passes by the hole for the...
Hi all,
First - I don't know if this is the right sub-forum to place this thread - please feel welcome to move it if it is better suited to another sub-forum.
... As it is I recently completed...
Hi ... well, as I wrote I actually have bought some car radiator coolant but as I am most always after more environmentally friendly ways of doing things I took a look at the fluid you suggest....
.... Please disregard - I've chosen to buy some car radiator coolant which will be thinned with demineralized water. Cheers, Jesper
Hi All,
I have just bought a 2.2 kW water cooled spindle for...
Hi again,
It has been a while since I have been posting on this thread ... hope life is fine where you are ;)
I thought I would upload a picture of what the machine now looks like (more...
Hi Zekyx,
... I can see that for some reason my reply to your info & link has not been added to the thread - so here again: Thanks for the info ... I have contacted with kampundkoetter and will...
Hey again Craig,
& once more thanks for giving a detailed feedback ;)
Hmmm ... the thing is that I probably could have made detailed calculations on torques, loads, stresses etc. if I had...
Hi all,
& thanks so much for your feedbacks. Reading your replies I realize that I probably should have been more specific with the 3D shape I attached so that it more precisely resembled what I...
Hi all,
Partly due to being a newbie I am using Estlcam to do my CNC millings, and I would be very interested in finding a way to either:
1.: “cheat” Estlcam so that I can make something like...
Hi all,
I am underways with building a new CNC machine and to this end am looking for some good yet reasonably priced BK12/BF12 sets (with BK12 angular contact bearings). Preferably from a vendor...
Hi again,
Thanks again to you for commenting and suggesting. A couple of comments from up north:
@Zorbit: I may consider using dowels for some of the holes on the z-axis - I guess they would...
