Hi everyone!
I've been pondering if I should do a project here or not, and thought, finally, I should do it. At least to have some journey I can read about when I am in my golden age, hehe.
But anyhooo...
My original plan was to make a CNC machine with the build area of 1700x3500x185mm, but life happens. So I was forced to come up with a new plan, and quick!
I had hit the wall, as you say, mentally when working on both my official work as a cnc machinist, as well as attempting to start up my own business, while at the same time building my own machines.
So after a two week sick leave, not that I felt better but I couldn't sit at home economically. I designed a new machine, with much less work area and quicker to build and mill out parts
So after half a year of designing and milling out all the components for the "Mini" version of the The C-N-C/The Crazy-Numerical-Cutter, I am left with this;
And that's it for images for this post, ahve some videos Iäll upload in a future post.
So the machine specs then;
Working area: 550x700x150 mm (X,Y,Z)
ATC 3.5 kW spindle
16mm Ballscrews for all axes, yes I know small for Y-axis but should be doable on my calculations and needs.
HGR20 Rails, with both narrow and wide cars.
Dual tool changer areas, one fixed carousel, one semi fixed, with tilt possibility to easy load and unload of material into the machine base.
4 vacuum zones, with ability to turn each section off, either mechanically or via electrical means.
X and Z motors are pulley driven, to minimize the envelope of the machine.
X and Y can, and might receive gearboxes of 5:1, Y-axis will then have planetary gears, and X-axis will have a pulley based "gearbox".
AXBB-E controller board.
UCCNC software.
HSS86 drivers for X, Y1, Y2, Z.
NEMA 34 4.5 nm, for Y1, Y2, Z.
NEMA 34 8 nm, for X.
Huanyang 4 kW 380V VFD
WHB04B 6-axis pendant
A no-name tool z offset sensor
And that's that, is this the best part list, NO!, is this the best I could design, NO! Is this the best I could do under a limited time frame, from idea to finished product and on a strained economical situation, kind of...
This is a good first machine, for me. To learn from all things covered, idea to design, design to production, learning to work as a designer hiring a manufacturing company with open dialog on the machine process, creating industrial standardized drawings for machine shops, some stress analysis but mostly skipped it and went with intuition on this build.
More to come, in this forum I hope.
But until then, thanks for reading and hope to have some interesting conversations here
