that's a crazy amount of PEEK shown at the end, and way bigger than any part I've seen made of PEEK before. I'm curious what the customer's specs were that led them to spend the $$$ on this, especially as a monolithic part with so much material removal.
Excellent video Stefan. You know just how much detail to show and haven't fallen into the trap of milking each one into more than one part like some other machinists. A happy and prosperous New Year to you Sir.
I try not to do multi-part videos anymore. Its very demanding from the viewer to dedicate that much time on a project and one can show a lot in 30..40 minutes if things are edited tight.
Fantastic video with something for everybody and the workflow belies the skill and experience. This content is why the internet is great, thanks Stefan.
PEEK - Polly Ether Ether Keyton, two Ether molecules in there :-). It's amazing stuff. I worked with an engineering project for a small drive system where we used PEEK for a worm gear that engaged with a powdered metal gear. The initial design had both gears in steel but they couldn't handle the heat. Never saw any of the PEEK gears fail. ATF was the lubricant.
Absorbing video about an interesting plastic. Suitable for higher temperatures than most thermoplastics and also high vacuum. Extreme material with a price to match.
Yep, Using them for a few months now, after a friend showed me how he uses it and I was hooked. Got a second hand one (The most basic one thats just the puck with two buttons, not the crazy starfighter control panel) and love it.
@@StefanGotteswinter I hope that is some old gage block that is only used for this purpose. I ruined one setting my tools with it in my younger years, ground myself an accurate, hardened block just for setting tools after that.
@@StefanGotteswinter BobCAD is located right by my house. (In Clearwater, FL.) You don't really ever hear people talk about it, esp people in other countries.
Normally you would want a micro-lift retract of .002-.010 as raising fully adds alot of extra time, though adaptive machining in general is reliant on a machine that has servo speeds with the ability to quickly ramp up and down in speed. IE not typically router tables or smaller diy cnc machines.
Why do you do manual tool changes? With the power drawbar, I would think that adding a tool holder rack at the back of the machine would make it easy to add a g code routine to pick and change tools automatically. Also, I highly recommend a cyclone vacuum attachment, when cutting plastic. It really keeps the mess down. I have a cheap cyclone push-type vacuum cleaner that I rescued from a dumpster and after removing excess parts I hung it on the wall next to my mill and lathe and it works wonders picking up chips and the cyclone keeps the filter from clogging up due to fine particles.
Love the video. It was suggested by Chris Stevens, that I subscribe to you. I'm just now getting into Machining. So I look forward to seeing a bunch of your videos thank you so much for what you do.
The ISO20 holders are super-cute. What is the three pin connector on the height gauge for - is that a data out connector, if so it could make a fun Arduino mechatronics project
i have worked many plastics. mostly i wanted "hard" because soft is crap. tool breakage was from plastic fusing to the tool. but one that wears out carbide? contraintuitive a bit. however; i watch utube to see NEW things. thank you stefan!!! poppy
Great video. Something you might want to consider for a 2 part operation like what you have been doing with your fixtures is to use a secondary work offset and do both operations in a single run. To state it differently as I don't like my current explanation: edit your program so you have both fixtures populated, then do all of the operations you can with tool 1, then the same for tool 2. This would reduce the number of tool changes you need to do. A drawback though is that you might have a harder time with any mid-part QC you do.
I don't see how that would save any time. Machine time will still be the same and he still has to manually move the parts from one fixture to the other.
Why didn't you also mill the outer diameter on the router instead of the lathe? You would still have to face it on the lathe, but it would have saved a lot of time indicating.
The PEEK Rod in its extruded form is very uneven and out-of-round, to clean it completely up to final diameter I had to be very carefull and I didnt want to take any chances, so I did it manually on the lathe (The stock was about 800eur).
The first time that I was required to make parts out of peek I can remember my boss telling me that the customer told him that the material is extremely difficult to machine. Boy was I ever surprised as it machined easier than any screw machine alloy that I had ever cut. What they don't know can cost them a lot.
Rad. Thanks for sharing the cad cam. What's your step down/ depth of cut? Maybe I missed it but didn't hear you say.. percent of mill width? In plastics I assume you can push it quite hard.. awesome 2nd op fixture. Using the thin wall flex. Thanks again!
A great object lesson on how an experienced and real machinist can still produce a short run of fairly accurate and no doubt costly parts on a lower end CNC against how one of us hobbyist's might Stefan. I'd go broke trying to make 25 of those on my manual mill.And that was a really clever holding method. That plastic type seems to allow a pretty nice surface finish even with such an awkward part shape. I'm curious though, since drilling is more efficient at bulk material removal than end mill machining, would the job not have gone slightly faster and a bit easier on your expensive end mills to use fairly large drills and step drill the part under size where ever it was possible to do so to remove the majority of material while still leaving enough to support those posts for final end milling to finished size? It's not a criticism of how you chose to do it, just an honest question. A most impressive height gauge and not one I've ever seen before. I really like that constant down force feature. I'd assume it can also be used for checking a parts vertical squareness like a Squaremaster? If so then it's even more impressive.
I considered boring out most material on the lathe, but I have other projects that I need the lathe and my workforce for, so I let the cnc cut on its own. As for drilling it out on the cnc, plunge-drilling/milling for stock removal is a thing, but i suspect the router might be to light duty to do that well. The height gage can do squareness checking, yes, but its not crazy accurate. They spec it out with 0,03mm squareness over 600mm.
@@StefanGotteswinter Thanks, I figured you'd have a more than valid and logical reason for just letting the cnc do all the cutting. .03 mm is about .000118" or call it 1.2 10ths over 600mm / 23.6" still not too shabby at all. I'm of course envious. :-)
PEEK is priced not in Euros but in arms and legs. Those parts are +90% waste. Just wondering...could it be possible to remelt the powder and use it for more parts ? +400 Celsius > hollow cylinder > hydraulic press...you figure it out.
Thank You very much for another example of so fine machining. From the title I assume that these are the spares for "time travelling lathe" of some Old Tony :). Best Regards
Really nice video the fixture, height gauge and problem solving, love it. One question on those cnc toolpaths, why so shallow stepdowns? Wouldnt it be better to do full depth of tool cutting edges with small stepover ? Is it more precise or reliable to do it this way?
Great video and som smart tricks. liked the chamfer op before any other operations to solve the vibration problem. I usually don't watch through cad/cam parts of videos, since I'm not into CNC, but in this case I watched the hole thing.
I like the fixture and thought a little. Does the part rest on the outer rim or on the studs? I shortly considered if rotating the part by 45 ° and bringing the studs in axis with the clamping areas would make a difference or even be of some advantage. But thinking more thoroughly brings me to the conclusion that You made the best choice. If there is clamping tension that leads to successive deformation along material being removed, that effect would be stronger along the lines between the clamping points. Compliments. Tolerance is impressive.
The Trimos in so sexy! I'd be envious but I couldn't make good use of it so will stick with have to make due with what I have. Love seeing the high end tools.
Hi Stefan. You talked about the fixture being overconstrained. I don't have any education in the field so the whole concept of overconstrained mechanisms is a bit hard for me to understand. Could you explain what makes this fixture overconstrained and what the practical implication of it are?
@@StefanGotteswinter Yeah I understand. Bobcad drove me crazy but that was many years back I think V22. Fusion did have some growing pains however I am loving it more and more. Have a good one Brother!
Hey, great video as always. Just curious about recutting chips that stay in the bore. Is that not a problem? Are you planning on installing some sort of chip extraction method? At work, if we don't have the coolant set up to blast chips out of a pocket we'll notice a difference in finish and dimensions.
Great video as always. I'll have to remember that chamfer first tip. But all those unnecessary retracts during the pocketing would have bugged me to the point of editing the code or the post. I know for 25 parts it hardly matters, but if I'm in the same room, I would go crazy. ;)
Purely curiosity: are there no good adhesives that would have been suitable for the application? This geometry seems to lend itself better to being an assembly than a solid part. I'm curious what requirements drove it to require 1 piece construction?
Was there any option for making the parts from multiple pieces where the posts would be cemented in with a high end solvent. That or 3D print. Always more than one way to skin the cat. Hope Doc Brown and Marty, er the customer is happy
@@StefanGotteswinter I don't know either. But if the customer specified a solid part, that's that. If these are prototypes for production parts i suspect that they would be injection molded. PEEK should be weldable with a PEEK rod and a high temp plastic welder. Did find this though. www.masterbond.com/applications/bonding-polyetheretherketone-peek. If that worked the posts could be made in two pieces expoxyed into from both sides. All of the assembly stresses should be transferred through the tapped holes. That's probably why the 4mm tapped holes are so deep. They get a fastener from each side. I suspect that this is for a di-electric field switch that mounts on the framinstat of the turbo-encapulator sub-assembly of the Flux Capacitor.
Stefan Gotteswinter don’t know if it makes sense in an non video environment, but you can Duty cycle the dust collection to not have it on all the time :P
Not much of a story - We where at a live show in Lichtenfels and as we where leaving the concert hall, I asked our driver to stop the car (on a much used road, no less), I jumped out the car, ripped the poster off a handrail and got back in the car. Since then its in my shop as a reminder for an awesome liveshow..
Nice and simple way of clamping in the fixture. Precision must be really good using those posts for centering. That will be remembered :-) Those parts can not be cheap. Lots of money just for the material.
G’day Stefan. Well thought out fixture it worked well. I understand this was a low part count therefore the production method used but it produced an awful amount of swarf and was time consuming. Excellent presentation as always, cheers. Peter
Stefan ,, did you ever consider 3D printing in PEEK the unfinished shapes .. and machining them from there? This is a material I plan on using with my printers (I have fancy one that is more or less an oven .. and my Raise 3D N2 PLUS should also do well with this material). GREAT SUBTRACTIVE MANUFACTURE video!! Best ,, Harry
"just to get an idea of how large a 600mm height gauge is" yeah yeah Stefan, we know you want to show off that Blind Guardian poster, and I won't complain haha
Um meinen alt Meister zu zitieren "nen Meter von dem Zeug kostet mehr als du in einem Monat Verdienst, also pass auf das du nicht zu viel versaust" Ich weiß nicht mehr genau welches peek es war aber zerspanen mit hm Platten für Alu war immer eine Wohltat wenn man die Späne zum brechen bekam, meistens endete man damit das man den laufenden span mit dem Sauger auffing oder per Hand aus der Maschine führte, das Zeug wurde für high End Laufkufen für die Medizintechnik, ich glaube in Desinfektionsmaschinen verwendet. Und as alawys nice video!
You would think that they would have had them 3d printed though maybe they needed the strength ? But hey I'm glad you got the job and amazing work as always
not only PEEK is high end, its ridiculously expensive as well at around 100 euros/kg. in fact it's the most expensive stuff we've got in our shop, far ahead of M390 MC, W720 and even titanium.
Nice looking parts. I can only assume, with them being the covers, you have already manufactured 25 flux capacitors. ;-) I paused the video and went back a few times to look when the popup appeared on the screen. I think it may have been your screen capture software but considering when it popped up I thought it was some kind of amazing high tech vibration analysis tool!
Did the customer think about instead making the 4 tubes separately and gluing them in place in predrilled holes in the larger piece? Seems like that would have been MUCH simpler as it could have been almost entirely lathe work.
Wow. I didn’t think the supports for keeping the top of the box from touching the pizza needed to be so sophisticated. 😲 Happy new year Stephan.
I've been looking forward to a new video so thank you for sharing it.

Thank you Robin!
Very good use of the flexture to clamp the part. In my arsenal. Thank you for the video!
Very clever setup! I like the fancy flexure fixture and chamfering the annular bosses prior to machining the bulk of the material. Thanks for sharing!
Those parts look really good. The CNC chamfer was a nice touch
Out of interest what was the CNC run time per part?
Runtime in total was about 1hour 40. You could reduce that by about a factor of 5..10 on a more rigid machine ;)
Add a couple of drive lugs to the outside and a keyway and it would fit on a turbo encabulator!!
FINALLY a height setting video that doesn't jog DOWN INTO the gauge block! lol ( a pet peeve of mine)
I ruined to much endmills that way ;)
@@StefanGotteswinter I hope that is some old gage block that is only used for this purpose. I ruined one setting my tools with it in my younger years, ground myself an accurate, hardened block just for setting tools after that.
Thanks Stefan, neat fixture. Milling in a Winter Wonderland! Belated Happy New Year.
Wow that stuff really machines well!
I don't know much about CNC, but is it necessary to raise the tool that much between cuts?
No, I just used the default 25-something mm retract. Normaly I would use way less, but I still learn BobCad and run it a bit on the safer side ;)

not only PEEK is high end, its ridiculously expensive as well at around 100 euros/kg. in fact it's the most expensive stuff we've got in our shop, far ahead of M390 MC, W720 and even titanium.
Nice! But i think it would be easier to 3d print these? Peek can be printed really nicely
Nice looking parts. I can only assume, with them being the covers, you have already manufactured 25 flux capacitors. ;-) I paused the video and went back a few times to look when the popup appeared on the screen. I think it may have been your screen capture software but considering when it popped up I thought it was some kind of amazing high tech vibration analysis tool!
As per always "You give good Demo"
Did the customer think about instead making the 4 tubes separately and gluing them in place in predrilled holes in the larger piece? Seems like that would have been MUCH simpler as it could have been almost entirely lathe work.
