Can The $38K SYIL X7 Machine a MIRROR Finish?

[@cylosgarage]

Add air bearings, and you can get better than 0.5μin Ra. I do this along with achieving 250nm profile tolerance. Also, you destroyed the tool when you probed it. You absolutely cannot use tactile probes with MCD tools.

[@Exandria]

Im very new to machining: why is that?

[@hendrikholz3997]

Hi @cylosgarage I'm a materials science PhD student working in the fields of micro mechanics. I'm super interested in what you are doing. We usually use focused ion beams to make small structures, like pillar, to test them. But that can alter the materials properties. Would it be possible for you to machine pillars of let's say 3 um diameter and 7 um height into a polished surface? Could be super interesting to my research community!

[@animus3d663]

Is there a relatively inexpensive way to optically probe?

[@barrysetzer]

The touch setter is extremely sensitive and moves. It didnt destroy anything.

[@dogface7966]

But you can cut aluminum with it just don’t touch anything!

[@WickeD72]

I was thinking 40k was allot for that part, I didn't realize you meant the machine. 😂 That's an amazing price.

[@barrysetzer]

Beautiful finish! Most of the time when I see a finish like that, it was done on a $300,000+ mill with a 80,000 RPM spindle

[@viliusr6974]

When you have time, you can use any machine you have. It probably took a coouple of weeks running non stop to polish that on syl.

[@BedroomMachinist]

​@viliusr6974 clearly diddnt watch the video, it was probably a 10 minute cycle with a mcd tool 😂

[@DGil504]

Nice video. I am getting a 7 to 10 RA on my Syil V5 all day long. They are great machines for the money!

[@tdg911]

Amazing finish. I had no clue these types of tools existed!

[@CATANOVA]

T Have used such tools. Normally they cater for extra wear resistance vs traditional carbide, for example when machining high silicone aluminium for extended periods. When it comes to surface finishing on the machine the prerequisites are: 1. Tool form and sharpness 2. Chip management so as to prevent fouling (coolant flushing) 3. Machine rigidity to cover off vibration 4. Machine accuracy when working at micron level step over and positioning between adjacent tracks.. 5. Top notch CAM programming because the step over would usually vary with Z height on the shape (ball mills tend to go linear tracking as the shape goes flat which can spread out the step over as measured on the part surface). Some of the best finishes I have seen on aluminium came by way of straight plain carbide that was highly polished (slippery for the chips) and diamond ground at the cutting edge for ultimate sharpness.

[@KylieGranno]

[@mattlarson9897]

I am curious what the step over was on that tool and the cycle time...

[@trevorgoforth8963]

.002" stepover, cycle time was 2 hours.

[@Packie318]

@@trevorgoforth8963 I mean a mirror finish speaks for itself, but I'm sure the carbide endmill would have looked a lot closer with the same stepover too. I would be more impressed and less skeptical if you had shown the same program ran with a similar carbide endmill rather than just showing the roughing pass with one. I think a side by side comparison would be the best way to show what a tool like this can do and if its truly necessary.

[@Chauvin-r9u]

​@@Packie318the reality is that carbide is much like cement hard rocks in a binder carbide cannot really get sharp like highspeed I know that it looks so cool all polished and feels sharp but if you were to see the edge under a microscope you would see the problem especially after using it. A highspeed end mill might come close but only for a few parts before the wear started to affect the finish. In honeing we used poly crystalin and mono lock diamonds to hone automotive cylinders the only problem in iron was torn and folded metal that gets dislodged during use. Going to a three stage honing head got you hundred thousand miles warranties on power trains. Laser honing was next where you have a polished bore with engineered oil retention groves burned in by laser it's totally ready to go but would add a few dollars to each block. When you make 4 million engines in a given program $2 is huge and until absolutely needed to cut oil consumption on hold.

[@terminalbyte7416]

How long did the mirror process take? Would have liked to see a timer in the machine to show how long the process took.

[@benjaminshropshire2900]

IIRC natural diamonds might actually form very quickly (potently faster than lab grown). The commonly cited formation times assume the form under conditions like what is seen today, but an alternative theory suggests that they could form much more rapidly under exceptional but short lived conditions (like magma rapidly moving towards the surface of from deep underground). But even then most of the diamond wouldn't be usable for anything but abrasive, would take many years to cool to the point they could be mined at all and even then would be hard to get to.

With the surface finish they got, it'd be at best a long wavelength IR telescope and not a great one at that depending on the wavelength. You're looking at lambda/10-40, not accounting for form error.

[@christopherleubner6633]

This is where the seconds grade CVD diamonds go. They use them for precision tooling bits. MCD grown by CVD is basically flawless so it can take unbelivable punishment. The diamonds must be rough cut with lasers then polished to the final shape needed. As long as carbon wont readily absorb in the metal the chips will fly 😂❤

I'm pretty sure nature can create diamonds instantly, a carbon meteor strike for example could do it in the instant of impact. I'd be willing to bet it actually happens pretty quickly underground too, you just need high pressure and temperature, both of which are always present in the centre of the Earth, but takes ages for them to surface.

[@pand0ras]

Correction here: You can absolute machine Iron with diamonds, as long it doesn't contain any carbon. Materials with carbon content will cause a diffusion at the cutting edge.

[@trevorgoforth8963]

That’s false, you cannot use these tools on materials that contain iron.
