CNC Project: FS4MG - "Not a Kern"

[@glamenz]

Hallo Stefan. I will continue in English for the broader audience. Nice to see you upgrading your shop. I don't want to be that guy, but please don’t encourage people to use the Erowa zero clamp system on a lathe. We use this and a different system quite extensively at my workplace. You can do at your shop whatever you want, but systems like this one are forbitten to be used at the lathe by the workers' compensation board (Berufsgenossenschaft). There are special versions of it that can be used, but the normal version can kill you if you, if the clamping mechanism becomes undone while it rotates

[@StefanGotteswinter]

Interesting! Thanks for the heads up - I guess the screw version, that does not use the drawbolt is fine for lathe use?

[@glamenz]

@@StefanGotteswinter yes that solves the main problem. When you talk with the manufacturer they are super cautious, when you tell them you want to use their products on a lathe. But there is more, if you want to put a vice in the erowa chuck, it has to be a vice without weak points in the spindel, centrifugal forces can get you. I used some funky setups myself, but if the trainees look above my shoulder i tell them that if they want to do stuff like that, they have to be super cautious about rotation speed and cutting forces

[@Brit_Toolmaker]

@@glamenz Thank you this is interesting reading. At work we use System 3R Macro & their original hydraulic Mini series across all of our machines. From what I know the 3R Macro pallet system is much more rigid compared to the Erowa system with similar repeatability. For CNC lathe & cylindrical grinding machining, we mainly use the hydraulic Mini series without any problem, and the same can be said for the occasional times we use the 3R spindle recommended Macro chuck 3R-600.22 for bigger parts, staying within the recommended electrode size range. We've never had any issues regarding security of workholding on any machine, including some very heavy machining on our VMC machines, if you compare the two systems the 3R pallets are incredibly strong as they are based on the indexing system used on Ward capstan turret lathes for indexing the turret.

[@MachiningandMicrowaves]

Very neat chuck system for proto/dev work and short-run manufacturing. I like the possibility of having a chuck on the lathe and on a CNC mill to move parts between machines with no loss of precision. I use a collet chuck to do that with microwave antenna feed parts, using a dummy D1-4 spindle nose on the mill. It's very repeatable in X/Y/Z but it's not so precise in rotation.

[@StefanGotteswinter]

i truely want a chuck for the lathe, yeah :-D That would be awesome to run back and forth, if only for parting off finished parts.

[@wolfitirol8347]

I use the same system a D1 4 camlock chuck which fits on lathe and mill whenever I opened the chuck precision was gone so I came up with this and bought my new lathe with D1 4... original Chucks are quite expensive but if you are able to make your own backplate it's cheap and precise....well I talk easy now I needed 4 bad backplates until my first was like I wanted her with 0,02 runout 25mm before the chuck is always the minimum that I accept 🫣

[@tonywilson4713]

*FOR EVERONE WONDERING ABOUT DRAG CHAIN CABLE.* In an earlier part of my engineering career when I was doing custom built production cells. I did projects where we built gantry robots and where we used 6 axis robots. There are 2 distinct kinds of cable you will find in catalogues from companies like Lapp, Belden and Olex - trailing and robotic and yes there is a difference. FIRST a basic lesson in copper cable. Typically electrical cables are made from strands of copper wire but you also get aluminum and gold for some applications. For all those who have watched Blondihacks series on copper boilers you'd know that copper *work hardens.* The difference between good quality electrical cable and poor cable is the quality of the annealing after the wire is drawn AND YES there's a big difference between manufactures. The main difference between cables for fixed applications and flexing applications are the number of strands and how the cores are encased in the plastic sheath. Fixed wiring has thicker strands and is simply encased in the plastic. Trailing and Robotic cables are made from much finer strands and they are installed with a dry powder lubricant so that the strands and cores can slide over each other. You'll see that lubricant when you strip the cables. Some of the higher performance multicore cables also have cloth sheaths between the cores and the outer plastic sheath. If the cable is shielded they have to do the same with the shielding in that its made from much finer strands. *- ROBOT cable* is the cable specifically designed for 6 axis (and similar) robotic applications where the cable doesn't just flex back and forth but also *TWISTS.* If you think about welding robots and spot welding robots they flex and twist in all sorts of ways. The standing, sheath and construction is all done for continuous flexing in ANY DIRECTION. This is why it costs a lot of money per meter but in things like welding applications its an absolute must if you want to avoid heartbreak. *- TRAILING cable* is what is used for drag chains. In most catalogues you won't see titles or descriptions or categories saying "drag chain cable" you'll see "trailing cable" and in the description you'll see "suitable for drag chains." Despite the label trailing cable is specifically designed for things like drag chains. It can be used for twisting applications but its main use is in drag chains going backwards and forwards. A COUPLE OF KEY POINTS A critical thing to look for is the minimum radius of the drag chain and the minimum radius for the cable. You should always pick a combination where the minimum radius of the cable is LESS THAN the minimum radius of the drag chain. Otherwise the cable will be stressed by the chain as it runs back and forth. The main aim of these systems is to NOT stress the cable or you will work harden the copper and it will eventually fail. When installing cable in a drag chain a major mistake is to use cable ties to clamp the cable to the chain DON'T DO THIS the idea is to let the cable flex. Most drag chain supplies have clamps for the end of the chain if required but typically you'll only clamp at one end so that the cable is free to flex. Most drag chains also have separators to keep cables from rubbing against each other - USE THEM. If you have communications, encoders and/or sensors don't simply throw the cables in the chain next to the motor power cables. I typically had AC servos with either encoders or resolvers so we had BOTH power and sensor cables. Its best practice to keep them as far apart as possible. Most of you will have power cables for stepper motors not AC Servos but don't forget that stepper motors are notoriously noisy by the nature of what they are. So its still sound practice to keep the power cables separate from the sensor cables. If you have a chain without separators use the air lines to separate the power cables from the sensor cables. So for all of you with these cartesian type machining centres you only need trailing cable but you do need to install it properly if you want it to last. FINAL POINT ON MOTOR CABLES WITH PLUG CONNECTIONS In this vid you'll see that Stefan bought a factory made cable for the spindle motor. For these sorts of motors with multi-pin cannon connectors or mil-spec connectors I ALWAYS RECOMMEND BUYING A MOTOR CABLE FROM THE MOTOR SUPPLIER. I have done a lot of work with such connectors over the years and they are fantastic when you have the right crimping tools or high quality soldering equipment but they are a nightmare when you don't. Stefan says his spindle cost €3,500. You don't want to risk that on a dodgy cable where its 100% your responsibility. I have never had a factory supplied motor cable fail but have seen what happens when cheaper options fail. Even if you are that 1 in 10,000 who gets that factory cable that fails there's things called warranties and customer support.

[@StefanGotteswinter]

Excellent breakdown!

[@tonywilson4713]

@@StefanGotteswinter Thanks. I like the fact I heard Lapp Cable at one point. They are one of those suppliers I always have on the list for a project. Its never the cheapest but I KNOW that it will do what the specification says. If there is another thing I would advise everyone in automation projects. USE 12mm barrel type proximity sensors with an M12 Plug connection whenever you can. 1) The M12 connection is a standard pin pattern so all of the variations from various manufacturers are interchangeable. All you ever have to worry about is the sensing range of the replacement. 2) These sensors have a 12x1 thread and its easy to get a tap so you can thread them into the bodies of things and just use 1 of the supplied nuts as the locking nut. Yes you end up with a collection of M12x1 nuts but then the talking monkeys like to lose them. So having spares is wise. The fine 1mm thread means if you rotate the sensor 1 turn you also know the end of the sensor has moved 1mm. 3) At 12mm diameter the 1/2inch (12.54mm) Pilot point drill from Dewalt cuts a perfect hole in aluminum and most sensor brackets are made from Aluminum. 4) On the maintenance side if the sensor gets "wacked" its a lot easier to replace the sensor and plug the lead on than replace the sensor an wire it in. Wait until you have to replace a sensor with a plug connection and you will never go back. Also the 7/16 (11.1mm) Pilot point drill makes a near perfect hole for the M12x1 tap. The one exception I have for that are sensors for hazardous areas I typically use 18mm sensors with a lead for that stuff. The reason is when you have a site with mixed standard and hazardous applications is less likely that a maintenance guy will put the wrong sensor in the wrong place.

The last years i used a small optimum metall mill converted with 4 closed loop motors 12.5Nm for milling nice small metall parts ( stefan helped me once while converting with an answer in a forum😊) and was quite satisfied so far but seeing Stefans project i think about buying a bigger frame and doing the same as he did. A friend with his router always comes to me machining when the material is harder than normal aluminium... the Optimum mill has no problems with steel of different kinds there is controlled cooling mimimal and normal also controlled by the cnc controller as the spindle speed...the parts are very close to spec and for my use more than exact enough 😊thanks to the closed loop system which is nothing else than a servo....

[@AttilaAsztalos]

Great choice! It's more a lost mould or stressed skin kind of deal than a filled steel frame, and I'm not entirely sure but I think I remember Thomas, one of the manufacturers, told me a few years ago the steel skin isn't very significant for the machines stiffness/stability. Might've just imagined that though, but it's definitely not a filled steel frame kind of deal. The larger ones, FS3MG, rely solely on epoxy granite though and are made in reusable moulds.

[@Andrew_Fernie]

As a middle-aged Brit I use metric and bananas equally and will use whichever unit gives an easier number. Measuring say, a table for example 4'6" in one direction and 700mm in the other. No messing with single mm or 1/64" and easy enough to be able to remember it. For smaller measurements I find thou to be easier and I have a better 'feel' for what it is. 20 micron just means nothing but 8 'tenths' I can visualise. What gets my goat is when dimensions are specified in an engineering drawing in fractional inches. Even my imperial machines don't have fractional dials ! Just give it in decimal. What the hell is 37/128" ? It's 'go get you calculator time' and swear at it the whole way , that's what it is. P.S. I am fully aware that inches Are metric.

[@joansparky4439]

@@Andrew_Fernie you could also work with 0.1mm (= *one tenth mm* ) or 10 microns (=10 tenths mm or *one hundredth mm* ). The core problem with freedom units is their varying multiplicators to get from one "area" to the next while metric is always based on 10. This robs one of of the round-fractionals like 1/8, 3/32, 5/16 (of which at a glance I never know which one is bigger or smaller anyway), but makes it way way easier to traverse scales, add several together or subtract and conversions to other units. 4'6" for example is one of those silly bananas sizes where you need 4x12 + 6 to get it all in one single value to be able to use it with other measurements to be able to traverse. Because _"It's 'go get you calculator time' and swear at it the whole way , that's what it is."_ For metricated people the _"What the hell is 37/128" ?"_ happens most of the time with any of those banana dimensions because it is so inconsistent.

Quick question if you dont mind. I remember that you had a pneumatic quick change spindle on the old ISEL router. That seemed even more convenient than this HSK system. How come you didn't go for a similar solution this time?

[@StefanGotteswinter]

Small diameter ISO toolshanks are a bit painful, hard to get, since there is no definitive standard like with HSK and also not very stiff. In reality you would have to go up to Iso30 size right away and then you are already in a size range where balancing to 25k is not standard.

[@luke1811]

To be honest I don't really know what the machine geometry measurements here should tell. Could be a bow in the Y-axis linear guides on the portal as well. I would use a granite square. Check for linearity of each axis first. Map it out. Write down deviations. Measure out the table afterwards, deduct deviations from linearity error. Also, one of the most important measurements, the Z axis perpendicularity left/right front/back was left out. If the table is out of spec you could do the cheap and quick fix by throwing a subplate on it and machine it flat. You said to be doing smaller work, so there should still be enough travel in Z left.

Mill scale pain? Try this: Storage tray with lid. Soak parts overnight in neat strong vinegar. Wrapping big parts in vinegar soaked rags in a plastic bag also works. Yeah, I was sceptical till I tried it

A nice follow up will be using the self proving characteristics of the square. By using only 4 points of the x and y rravel you can measure both machone and squ.are at the same time.

100K subs coming in soon Stefan. What a journey it has been.. Finally have a nice CNC!

[@wgn567]

Great video again Stefan. One small remark from my own electronics background knowledge, better not to put the unshielded motor powercables next to the unshielded data control cables in one box. They could interfere with eachother. And hard ground all metal parts of the machine with its own earth cable (preferred 4mm2 or bigger) also the metal box. Looking forward on the next video showing the results and obtainable precision with this new cnc machine.

It's like Christmas. Looking forward to operation.

[@peterbennett1792]

What brand is your T handle torque wrench Stefan?. I have used Iscar ones on the past and they have not lasted.

Not a Kern..........Yet!

[@SimonPEdwards63]

You had me with the title, Kern is visiting us in two weeks, presumably to try to sell us a Micro HD.

[@mingyanglu8679]

hello stefan, i am in the process of building an enclosure for the same machine and i was wondering if in your case, you bolted the machine to the frame from behind in addition to the two front holes?

[@juanmartin1165]

Lo-fi machinist/fabricators are the most clever people on earth... You have to be😅

[@dimimexmaquinadosyautomati8217]

Hi. Where did you buy the frame?. Can you Share the contact?

[@R2_D3]

''Stefan needs another project, like he needs another hole in the head'' ROFL!!

[@jamesmorrison4713]

The title “Not a Kern” attracted me to this video. I found it extremely interesting and informative. 😊

[@steveggca]

Hi Stefan ,what a great machine! looking forward to seeing it evolve. About a month ago the channel marco reps did a factory tour of the spinogy factory , you get to see some details of the inner workings of the spindle. Does your spindle have an encoder that allows for rigid tapping? He also is constructing a machine using linuxcnc and a watercooled spinogy spindle. interestingly he is using EtherCat servos, that allow for entirely digital domain servo control instead of +/-10VDC .

[@garychaplin9861]

Great video. Thanks for the concise description of the equipment, I look forward to seeing the build and operation.

[@svenkrause3433]

Danke Stefan für das Video...ein paar Dinge waren wieder hochinteressant! Wenn man nur mehr Spielgeld hätte...😝😉 Ich hätte übrigens noch 4 Tütchen Metaflux hier. In meinen Augen für HSK Spannsätte am Besten geeignet! Wenn du was brauchst...kein Problem. Machen wir dann im Discord aus...👍

Gehört in jeden Haushalt!

[@angelramos-2005]

Great video,Stefan and very precise and quality machine.Thank you.

[@bigbird2100]

Great video 👍 Stefan nice to see you got to go primitive and work in the great out doors and swing a hammer and finish with an angle grinder and paint😅

[@T1nCh0]

I remember this router from a Marco Reps video and it was a beast one.

[@vism_xyz]

Really rigid 💪

[@bobuk5722]

Oh, so that's why it's called 'stick' welding ......

[@RustyInventions-wz6ir]

Very nice work sir

[@timkusicko4921]

Cool Tool

[@tommelomme6761]

I bet we soon have a video making those palette! Nice!

[@stevenrichardson7882]

A nice compact router well narrated in a 2nd language? 👍

[@charlieromeo7663]

This project will be fun to watch.

[@1ginner1]

Hi Stefan, that's a really nice clamping system. Looking forward to seeing how you align the spindle.
