The guideways are made out of aluminium. We're hard-anodising them (at low temperature), the final lapping reduces this film thickness and creates the precise surface and form of the guideways. Being anodised, they can't grow an oxide layer any longer (as there's already a manufcatured aluminium oxide layer on them). The spindle is not made from aluminium.

You are very welcome to visit and throw stuff into the SEM :)

Damping. Thanks for correcting a non-native speaker! :)

It's shot with the fantastic Freefly Wave - I've been constantly amazed what quality is available with relatively affordable high speed cameras nowadays. This shot was recorded with 390 FPS / 4K and is played at 24 FPS - so 6.1% real speed!

On their website it says it can do 2K at 1461fps. May we see that? It will require quite a lot a light. What lens are being used?

Climb milling is the prefered milling direction on backlash free machines. Better chip formation, as the chip starts "thick" and the tool is not rubbing. With traditional direction milling, aluminium is not easy to mill dry/mql based like in this shot.

Yes! The SEM is probably my favourite measurement device at Kern. It shows so much what you can't grasp with your eye / normal microscopes. Thank you for the kind words on the video. I'm by far not an expert in laser material interaction, and i usually don't talk about stuff I have only a basic (textbook) understanding off, so this video was me just explaining what I see and not doing any theory. If you are interested in laser-material interact, a fantastic book on this is in the SPRINGER series in Materials Science: Laser Precision Microfabrication (Joi Sugioka et al) from 2010.

I've been very surprised with it. The last time i went shopping for chinese machines was 10 years ago, and back then it was a horrible user experience. While I do think the infrared diode could use a little bit more power, overall it's a sweet, sweet little machine. Thank you for the kind words on the video :) seems like I should do some more SEM videos then?

@@MarvGro Yeah china stuff overall today vs 10 years ago is something completly different indeed. And yes.. moar SEM please :]

I feel you Amish. *coughs in swiss* 6C tools... :'(

Thank you for the kind words! I also was really surprised what this little machine is pulling off :-)

dumb dumb (sped up)

Schon ziemlich lange, aber nicht sehr aktiv seit ein paar Jahren. Die Arbeit für lange KZbin Videos war mir eigentlich zu groß.

Do you mean the toolpath tolerance?

@@angrydragonslayer 2.40 cyl 32 tolerance 0.0013mm maybe after lapping...

@@user-qn8nm3gy6dthat's not part tolerance but rather toolpath tolerance, telling the machine how far from the programmed toolpath it is allowed to stray to maintain speed. With cycle 32 active, the machine may for example replace sharp turns (such as a 90° bend) with a fillet of the specified tolerance to prevent the machine from completely stopping when undertaking the turn.

I highly recommend googling it or looking in the owners manual for your control system

@@angrydragonslayer ou. Thanks! I read cylinder:) That cycle need if you progfamming from milling machine. Or you have a very good post. And press need button. Thank you for the training!

EVERYTHING is literally and figuratively in the video. Cheers!
