and! I was mesmerized and watched until the end. This is really beautiful processing. I also want to get an NC machine someday. Thank you for the good video.
God I'd love a Datron CNC with a fully kitten out tool chest 🥵 Guessing you're not using ethanol as a MQL for acrylic parts, but whatever it is, it seems to be doing the job :).
I know you predominantly use Datron endmills, but isn't that Hoffmann 203205 lovely? I have a few of these 5-flutes, also 203203 and 203204 and they just leave a decent finish on thicker parts with just a few full depth passes 👍 Amazing part, btw... As always
These are all machine finishes, you can just about make out some of the machining lines where the paths cross over. The only issue is the paths to get them that clear are sloooooow on larger pieces.
Cool video. Why do you conventional cut with tools like the chamfer tool around the outside instead of climb cut? To make sure a chip isn't pushed into the part?
Finishes on sidewalls tend to come out better when conventional milling acrylic. Some of the paths are also shared with my Delrin tooling, which benefits from conventional for burr prevention.
@@PraetexDesign interesting, I have machined delrin and found good success using high speed tooling but I've never machined acrylic or tried running them conventionally. I'll keep that in mind for the next time. Thanks for your reply
@@ExRazR Whilst it would depend on your machine and available tooling, the actual geometry for this isn’t hard. Getting the right finishes can be challenging though. Diamond finishing is very demanding, but the Datron tools can get you 90% of the way there.
Some people get auditory stimulation from different things, like you might get a kick out of watching. ASMR videos typically have something going on where the sound is specifically clean, with no dubbing etc.
@@texasermd1 Yeah it’s more generally used for videos that will just have their plain sounds quite often. 99% of ASMR content is people just flicking the mic and whispering so it’s not a high bar 😂 I find a lot of the workshop sounds are pretty satisfying, so that’s where it applies here.
@@keibohow69 It’s a bit of an open question really, it can be anywhere from a few hours to weeks depending on how many development stages are involved.
as a machinist myself, who hasnt machines very much plastic before, why choose carbide drills? when you're making low batch and prototype parts out of plastics, with either mist coolant or no coolant at all, why not just use HSS drills? surely the cost benefits are there
@@thisismyaccount456 These small carbide drills aren’t expensive, but they do come with H6 shanks and are much more comfortable with higher speeds. Most HSS drills don’t feature ground shanks that fit into either 3/6/8/10mm holders, they tend to be nominal. I’d need to buy specific toolholders to use cheaper drills like that.
When machining polymers, you still want fast cutting action and low friction, bc when plastics get too warm you get pretty quickly a bad surface finish or worse.
I always thought acrylic would get frosty when you machine it. That was totally crystal clear, is that because the bits of a CNC spin so fast that it cuts and buffs at the same time? Or am i just completely misunderstanding the material? Also, how many probes have you gone through? That thing looks so fragile a stiff breeze could snap it in two 😅 Awesome work all the same though 👍✌️
Well it depends. In the very beginning he was using a single flute endmill, and you can see the acrylic is very much frosty while he is roughing with it. But when he switched to the 5 flute (single flutes give poor wall surface finish compared to a multi-flute tool) and then slowed it way down it was clear. It's all about surface finish. If you can cut it perfectly smooth without chatter/tooling marks it will be clear. Also, I'm not sure his feeds and speeds, but I suspect the datron he has spins way too fast for a 5 flute tool (i have never used a datron so im no expert there), there is a lot you can dig into with that, but I'll just say because datron spindles go so fast, generally you would use a lower flute count. And because he used a 5 flute and had a very slow feed I'd bet there was some rubbing going on which helped it become clear, which you alluded to in your comment about the endmill buffing the plastic.
@@jacobmiller6664 0 flutes can give great wall finish but you have to go extremely low on the feed, use polished endmills and have good cooling. The 5 flute is not only more rigid, great for full depth finishing, but he can feed at the same rate he was roughing. He was feeding at 880m/min but with a .02mm chip load with the 5 flute. Lower flutes are actually better for slow spindles and less rigid machines that can't do high feeds or heavy chip loads. The keys for clear finishes are good cooling, rigid machines/work holding, and sharp tooling either polished or dlc coated. Also cast acrylic is much better to machine for good finishes. Extruded is no bueno.
Excellent work and engineering. Please tell me what precision class the machine has: - N (Normal precision) - SP (Special Precision) Or in millimeters (0.001-0.05)
It looks good, but: • Why not make the part thinner (reduce the wall thickness between the pump mount and the liquid reservoir)? • What’s the purpose of the arc-shaped wall near the intake hole for liquid from the reservoir?
@@dendobrunia6861 Good questions, however I didn’t design the part so I can’t readily answer with accuracy. I believe the arc section is to help reduce vortices though and bubbles being sucked straight into the pump inlet.
@@PraetexDesign It seems to me that this part of the design actually negatively impacts functionality, reducing the intake area and increasing fluid stagnation under the arc (this will be especially noticeable when using dye). Overall, great execution! I didn’t notice any milling marks on the final part. Keep up the good work!
Great work Alex, Lucas can’t wait to get it in his build.
That's not machining, that's pure art!
That's not art, that's an engineering porno :)
Wow, I didn’t even know it was possible to achieve such a perfect finish when machining acrylic
I’m also didn’t know if was possible to finish clear effect, curious what rmp need to get this clear cut 😊
@@linassapnagis2174 It shows you the RPM on the tool data, 28k rpm with a DoC of 0.2mm :).
@@sarahjrandomnumbers Режимы резания ещё не всё, очень важна геометрия и заточка инструмента.
@@dok.Sanger They asked what RPM was needed to get a clear cut. I told them. Yes the tool needs to be sharp... Obviously...

Everything here is art, the video, the lighting, the shots, the machine, the machining, the machined part, everything 💯
wow that finishing tool left a perfect surface almost like it was polished !!!
Love it! Such an expensive machine but the results are flawless.
I noticed you use the Flycutter after finish for ultra great surface. Do you calculate parameters? The surfaces look perfect.
We need more full builds with you back on camera Alex
From my algorithm. Reminds me of the format of tungalloy videos, and other cutter videos. This is an excellent video.

omg, you are back
Absolutely amazing 😮😮😮. What the maximum spindle rpm of your machine is, an what kind of fluid do you use for acrylic?
Started thread milling up, I see. 😊
That O-ring tho!
What coolant did you use on the acrylic? Hopefully not isopropyl alcohol since that degrades acrylic and makes it crack over time.
I am wondering why you made threaded holes for the mounting screws in the topplate instead of just using through holes. Is there a specific reason?
I love your ASMR man, how does the piece stick to the table for the last setup?
@@trollman1376 That’s a vacuum table, the card acts as a diffusion layer

Did you polish the surface or do any treatment to make it so clear? Your works is always amazing, love to know the final build.

Cool video. Why do you conventional cut with tools like the chamfer tool around the outside instead of climb cut? To make sure a chip isn't pushed into the part?
@@gulch1969 You get better finishes in acrylic when conventional cutting for side walls and chamfers I’ve found.
@@PraetexDesign thanks for the reply. I haven't cut much acrylic.
Cool, but what about aluminium and steel?
Is there any reason you're conventional milling the exterior contour? Is there a benefit with machining acrylic?
Finishes on sidewalls tend to come out better when conventional milling acrylic. Some of the paths are also shared with my Delrin tooling, which benefits from conventional for burr prevention.

Great, but when will all this become fully automatic, without human intervention?
@@ural859 it already is, and has been for many years. Unless you mean also drawing the paths and designing the piece to begin with.
that's one THICC block
Which cnc machine is this one ☝🏽?
for a total beginner, how hard would this be (with many patience and proably dozens of retrys) to machine this yourself on a small mini-mill?
@@ExRazR Whilst it would depend on your machine and available tooling, the actual geometry for this isn’t hard. Getting the right finishes can be challenging though. Diamond finishing is very demanding, but the Datron tools can get you 90% of the way there.
Nice looking pump reservoir. Just wondering about the ASMR part. What does that mean?
Some people get auditory stimulation from different things, like you might get a kick out of watching. ASMR videos typically have something going on where the sound is specifically clean, with no dubbing etc.
Oh, I had read that it stands for a tingly feeling running down your body so using it in this context and other RUclips videos seems confusing.
