I was thinking of a single zag but in a different orientation, will see what simsolid has to say about it, it would definitely be good for weight reduction.




do you mean the first two...

I'm starting to think you're just pulling my leg, wish there was a block function on the forums, the occasional good comment from you doesn't seem worth all the annoyance that you cause

ok Pete...

and what would that prove? would I have the equipment to measure real world data to confirm anything?

$150 yrt + $100 laser cut steel round + $180 grinding both sides = $450 for stiffest setup...

well you haven't actually said anything specific about why you think the price of a stiff rotary is way up there, so mind sharing actual real world data why you think that? especially in the context...

with steel fabrications the deal is simple, if you can't stress relief, don't do fabrications. I don't see any reasonable solution for a massive router like this other than buying it. you're lucky in...

if you mean to have the ends completely closed off, that only increases stiffness when there's no internal ribs, with ribs that doesn't matter as much. or do you mean to have an inner...

where does this comes from? I already mentioned YRT bearings and their cheap price($150), you slap the bearing under the 300mm plate and its rigid beyond what you'll need, where is the problem?

that's a much better situation than here in germany $5000 for machining but that's 4x the average monthly income.

that's a great price, is the company in europe by any chance?

where do you live then?

without stress relief you're going to run into all sort of problems with a twisted frame, how much of that budget is the machining price?

whats your budget? maybe you could buy something like this eg.

in theory its simple, you need a vibration motor, which is a motor with an uneven weight attached to the shaft and you need to achieve resonant frequency of the welded part and keep it there. in...

$500 per rail, $200 per carriage and about $3000 for a ballscrew

you can take your chances with chinese c3 stuff in which case:

$100 per rail, $50 per carriage and about $600 for a ballscrew

some further work with internal structure, trying to minimize local sheer issues. bed target length around 1800mm, cross section around 320x320mm, weight is ~400kg across all 3 versions.

third...

it seems that SC-15P is both steel filled and self leveling and de-airing, they showed some images of a flat surface covered with it to create an air bearing surface

you don't need actual results in diy, most people make this mistake trying to get real stiffness values for hobby machines, all you need is to compare between iterations, it all happens on the same...

take a look at simsolid, solver takes minutes to solve complex stuff. meshing sucks I agree, which is why simsolid doesn't use meshes. you can add different versions of the same model and it...

no, just no. it's neither easier or faster. I'd trust computer results with my life over anything I'd write on a piece of paper, I even use a calculator to add two 2-digit numbers. I'd never get to...

any luck on their forums? they(titans) also have a discord channel that they respond to. on a other note they mention blaser products for flood coolant so maybe that's a starting point. I found two...

solidworks has great coupled thermal-flow simulation. straightforward and easy to setup, for heat transfer between solids and liquids eg. watercooling of components. so far I haven't been able to do...

are you designing a $250,000 machine? otherwise it's a pointless endeavor, manufactures give stiffness values for static and dynamic stiffness, that's more than what you'll ever need. you don't...

you have a 3d model from a company and then you apply the same material in cad, there's nothing more to it. you want to model the ball bearings/rollers inside? why in the hell would you want to do...

why do you want to model them? just download the 3d data from the manufacturer

you won't find anything if you search for 'gibs' search for 'wedge' instead like this https://www.aliexpress.com/i/4000336848633.html

I prefer the TS3 wedge to clamp the rail from the side....

you can get anything you want in russia(eg. tanks and rocket launchers) or china(eg. any electronics there is)

CBN's are something else

damn, nice catch, I assumed since it's ceramic it doesn't need cooling, you use ceramics to cut inconel dry so why do you need coolant for aluminium? it's pretty weird

stepper onlines integrated 750W and T6 series seem to have some tuning software in the downloads section

sounds like separating chips from the coolant is a major hassle. I recently found ceramic endmills for soft materials. It's a swiss company so the price is probably out there, but if endmill life is...
