Good find Peter.
The bolts joint will be interesting to see.

Good find Peter.
The bolts joint will be interesting to see.
Trying to find inspiration for how to do the way cover for the z axis on a bridge mill.
Can't really find good pictures of the cover.
The bridge mill will typically have very little space beneath...
This looks amazing
Agree
Compare the UMC350 HD vs the non-HD and there are big differences in both speed and torque capabilities
That is great.
I was just going to mention it that it seems many think slower speeds are also okay. And that opens up som opportunitets when it comes to building the rotary.
This is a Hermle C22...
Yes of course. For some the increase in productivity justifies an increase of 5x in the price of the machine.
And of course many are doing really high end high speed manufacturing in 5 axes and do...
The new Haas 350 HD has a max speed og 100 deg/sec for B and 80 deg/s for C.
DMG, Hermle or Kern might be in a different league. But I guess higher speeds are mostly (in the real world) only for...
Looks perfect :D
No not me :)
Inspiration
This kit was up for sale here for 4k USD
Somebody got themselves a nice project :)
Got a good look at the frame here.
Bearing blocks dont have anywhere near the same stiffness as solid steel. So to get decent results on this analysis you need to model the correct stiffness at that point.
What are the travels on this kit? How large is the table? Looks good.
Looks like they recomment 24k rpm and 800mm/min for 6mm WOC and 6mm DOC for their shortest 6mm bit.
That is 0,033mm/tooth. So maybe just start there with less DOC/WOC and increase as much as you...
I think it is better to start below the recomended load (maybe 50% of the recommended chip load for the cutter you have).
A router is not as rigid as a VMC so can not do similar chip load.
When I...
Your router looks very nice! Good job!
I would start at half of that chip load and increase from that.
If it's a quality carbide cutter you can go full rpm on a 6mm bit. But it needs...
I see you have the WJ200 VFD and it has parametres for tuning.
About 4-pole vs 2-pole.
Historically you could buy motors with two sets of terminals. 1 for 2 pole operation and 1 for 4 pole.
With...
I have not read everything in detail, but here is a suggestion:
I think this comes down to VFD tuning.
The motor will run at 10A no problem for a SHORT time with out overheating (thermal inertia)...
I have the same problem with UCR201
There should be a fix for it, but I have not tried. Check this: https://forum.cncdrive.com/viewtopic.php?f=3&t=3598&start=10
Cool. Didn't read it all, but it seems there is a significant difference from an uncompensated system.
Could a simple solution to your temparture stabilizer be to cool the ball nut mounting block and the end bearing blocks on the screw (maybe one of them is enough) ? Those are stationary parts you...
The thing is most hobbyists dont do 1.5kW cuts with their 1,5kw 24k spindle.
You need the power capability (current capability) so you have enough torque at lower rpms. But with smaller...
If you can locate a machine shop within driving range I think they'll cover what you need. But if you don't want to order a 6m/12m piece of steel you might need to adjust your plan to the dimension...
This looks very good. Glad to hear the parts are still straight. I think it helps that you have big cross sections relative to the amount of material removed.
Can't you make the gap wider?
Is there any gap on the front side?
I don't really understand your model. Is the chip tray the sheet metal beneath the table with a very tiny gap on the sides?
Looks very nice!
If you made this base narrower and filled the space between the brackets in the sides and bottom with epoxy granite you would have a stiff and damp base for milling metal.
Thanks :)
Yes I guess a 30 taper is more than sufficient for what i want to do.
Yes
Great thread btw :)
I'm thinking regular HS machining and enough low end torque to do face milling.
Is it worth paying more for HSK40 vs ISO30?
For a machine like this. What is your feeling about spindle taper and power.
I asked Olispeed about their SAB150 with HSK63, but at 8500 euros it's a bit expensive.
And HSK63 is expensive tooling....
