Oh, thank you 🙂

..is planned 😉

The ball screws I use are from Isel. They are manufactured in Germany, but are of low-cost quality. They are rolled and in tolerance class C7. The pitch is 4mm for X and Y and 5mm for Z. In terms of accuracy, they are not bad at all. Unfortunately, they are not preloaded, which is why I would like to replace them one day. I haven't installed any Chinese parts except the guide rail for my sliding door 😉 The stepper have a torque of 2NM. Good luck with your construction..

Thank you 🙂 ..of course you can ask questions.

I love it. It makes every tool change a pleasure.

I'm glad you enjoyed it 🙂

Yes, you are right. But setting up a new tool is no big deal. Before I would build something like that, I have other little things on my wish list 😉

@9voltprojects Fair enough. I do quite a bit of turning on my mill. I have a stick tool block and have found this a hurdle so am mid way through building a capto 4 based block that should make tool changes a lot quicker. The list is always too long!

Vielen Dank! 😉

Thank you a lot 😏

Hallo Anton, ich werde zukünftig einige Videos über den Bau von Spindeln veröffentlichen. Das wird allerdings noch etwas dauern. Einige Deiner Fragen werden dann in den Videos beantwortet. Vielen Dank für Dein Interesse und schau einfach von Zeit zu Zeit mal wieder vorbei!

@@9voltprojects Hallo Chris kannst Du einen Link zur Spindelpatrone - also dem Stahlteil in deiner 4. Achse angeben? Das ist doch ein Kaufteil? VG Anton

Thank you!

Thank you for your interest. Sorry, I do not share my Cad models

Thank you! I'm not sure what exactly is meant by 'angle indexing'. The servo motor has a 17bit encoder and can rotate the spindle to any position (angular steps) of 360°/131072. The servo driver also provides an index signal every 360°, which I use to measure the spindle speed with my controller(FPGA).

@@9voltprojects Meaning, can the lathe rotate in degrees and lock in position, for the mill to come in and machine a flat surface and then on that flat surface? For example, say I want machine a hex shape at the end of a rod, and then engrave one of the faces, then rotate, and drill thru another face. In other words, instead of RPM motion, I get angular rotation with locking in positionn.

@@PaulG.369 The answer is yes and no ;-) It is possible to engrave the radius of a round workpiece, which I have already done. But I can't engrave a flat surface in this way. That would require the turning spindle to be mounted on the machine table or the gantry to be movable in the Y direction (milling view), which is not the case. Yes, I can drill small holes in a clamped workpiece at any angle. However, this is only possible to a very limited extent because the spindle shaft is driven by a belt and is therefore not absolutely torsionally rigid. A worm gear would be necessary for this. I prefer to do such work on the rotary table.

I would never want to admit that I didn't make it. So I'm always condemned to success ;-) Thank you a lot.

Thank you very much for the kind words :-)

Vielen Dank, freut mich das Dir meine Konstruktion gefällt :) Da ich keinen weiteren Platz für eine Drehmaschine hatte, musste ich halt erfinderisch sein. Elektronik mache ich quasi seit ich laufen kann, deshalb auch der Eigenbau des Controllers.

..just a hobbyist with skilled hands :) Thank you!

Thank you! All spindles were designed and built by me. The HSK tool change interface is from Gühring.

@@9voltprojects thanks you my friend

The spindle bearings are from FAG. I still have to look up all the part numbers. I'll do that together in a future video about building another spindle.

You do not need a CAD file for the leveling plates/blocks. They consist of 40x30x10mm steel and an m8 leveling screw in each corner. There is a through hole in the middle of the plate for the rail screw. And that's it. The challenge is to get them all at exactly the same height. For this you need a reference, e.g. a granite ruler or something and a very good dial indicator. It took me a week to get it right, so be warned. The clamps to straighten the rails are very specific to my machine. I don't have a CAD file of them, I made them right out of my head. The rails of my X and Z axis I also straightened with other tools, but that would have been too much for the video. Just build something to bring the force to the point of highest deviation. I was surprised at how easy it is to straighten them.

I noticed for X axis you did not have leveling plate, have you grounded base? Also with leveling plates you need to level everything together, as without central bolt and rail they won’t stay?

I used double-grinded precision steel plates from Meusburger for the bridge of the X-axis and the machine table. That's why I didn't make any further adjustments to the X-axis.

Большое спасибо.

Thank you a lot!

ありがとうございました。;-)

Thanks ;-) Unfortunately, I don't have any video footage of the spindles being built. I'll see if I can find some pictures, then I could try to make a "short" out of it.

@@9voltprojects that would be pretty cool, i'll be waiting for the notification

Dank Dir!

Thank you, I am very honored :-)

:) :) :)

Thank you.. I think anyone with good metalworking skills doesn't need a construction plan or CAD files from me. I've also just copied most of the things from the big boys in the business. Less experienced hobbyists I would advise to start with a smaller project.

Thank you and yes, both were built on my machine in the video

​@@9voltprojects Did you have a grinding process? What is the runout, and what rpm are they capable of? I really appreciate what you have done!

merci beaucoup

..not yet on insta

@@9voltprojects I love your milling/ lathe machine this is what i like to built also. It is so clever how you combinate things. How can i contact you ?? Thank you for reply

Thanks :)

Thank you!

Sorry, I don't offer kits. I only do it as a hobby. Thank you very much!

Understood. Have you considered sharing your designs either commercially or under a creative commons license or alternative open source license? I believe your machine would be liked by many others who might improve upon your design and share those improvements as well.

Danke :)
