Shortening the tool length it would cut better.
I know! Only had this Endmill on hand.
Impressed all things considered
At 3:02, the tool changes the cutting direction. U can hear and see it. That can cost you the tool. But nevertheless, good video.
Good Ear! For bigger pockets i like to tick the "both directions" box. But here for this small pocket with high speed it sounded horrible. will take this into account in the future! Thanks
I've got to echo the sentiments of others that the chatter is pretty bad with some of these cuts (mainly the 10mm adaptive paths). Backing off on the chip load for those paths would improve your machine life.
However, as far as desktop mills go, the machine looks well-built (if quite over-priced). I won't go into specific brands since this is your official CZcams channel, but there are several other manufacturers offering much larger-format machines with 1.5KW spindles and all ball-screw leads for similar (or even less) cost.
Why is this particular machine so pricey?
Plenty of room for programming improvement to cut down more time. Looks good though.
I have to add: The Part was finished in 14mins! So even faster than announced ;))
Cuts that deep with a 3mm? single flute. Impressive. Noisy and the spindle obviously doesn't like it but Impressive non the less 👌
i would guess its rather the sheet metal vibrating, i have a verry similar machine, and thats the way it Sounds like that
It is a 4 mm bit.
@@Basement_CNC Bingo! In the retail units this was counteracted with thicker sheet metal and much more vibration absorbing foam.
It`s interesting to know stepper driver type and voltage?
They are custom closed-loop steppers in NEMA17 size. Reaching 7000mm/min with 4mm pitch ball-screws.
❤❤❤I love machine
Great, but surely it would be quicker without repeating the same party so many times? All that motion takes time that could be used for actual cutting?
Am I missing something?
Mill one slot, move to the next mill that slot and move on etc etc. Then cut around the perimiter to complete the part
Its a very small Deskop CNC. It repeats the same Part as finishing passes to get a better Wall finish. If it has to be an only functional part, i could cut the time to under 10mins for sure.
How would it compare with electro-erosion??
You mean wire EDM? typically only use that if you want to cut through something all the way through not pockets (granted you could do it with rods also)
@@ChaseRayfield88 I wasn't thinking of only 1 wire but 17 instead, plus a circular perimeter to cut 12.6 mm dia. discs out of a 1mm thick metal sheet, e.g. with 17 #53 holes in each disc...
Why would you use an ultra high precision (and ultra slow and expensive) cutting process for a hobby quickie part like this? Apples to oranges
@@PaulG.369 The question remains: how would it compare with electro-erosion?? Lets leave fruits out of it, an approximative non-evasive evaluation would suffice in lack of any better opinion. Ultra-precision? How much?? Expensive? Idem. It's for SS430 and possibly even harder metals, by the way.

Instead of asking such naïve questions, all you have to do is type in "EDM vs milling", or "CNC mill vs router", in the search box.
Come on bruh.
Get off your high horse and do some basic research on your own. Aint that difficult.
what is the cam program ? what is the end mill brand ?
As CAM we used Fusion360, End-mills are our in-house brand.
Effaçage ¢ompul$if déte¢té.
Sounds like pure torture. I'm actually surprised the part came out looking semi decent like this. There is a reason why you don't use routers for soft materials to cut metal - the machine/workholding lacks rigidity. Surface finish is nothing but chatter. You can just hear the tool deflecting and vibrating the whole part, instead of taking a proper clean cut.
Not bad for a hobbyist making a couple of parts in the garage I guess.
Hello Paul. Can you point me out where you see chatter in the finished part? The Spindle shaft is hardened to 56HRC and grinded to 0.005mm runout running in very big 15x32x9 angular contact bearings. The whole frame uses 15 and 20mm aluminium plates running on 15mm Linear rails with 4 HGH15CA Blocks on each axis.
To answer your question: The Vibration you see here was caused by big stainless steel dust covers that act as cover of the whole floor and the back of the machine. On the Retail units this is counteracted with using thicker sheet metal and much more vibration absorbing foam tape everywhere the frame contacts to the housing.

Sure...
@ 14:28 all the walls and chafers have obvious vertical lines
In production that would would considered a manufacturing defect.
It may or may not be your machine. But it is common sense and general knowledge in the cnc manufacturing, that one should avoid using a router to cut metals.
Your entire setup is vibrating. And as long as it does, you can never expect smooth surface finish.
You can probably improve your setup by mounting the aluminum workpiece directly to the metal table after deburing the edges of raw stock, instead of onto the floating particle board (which is more than likely bowed out from clamping pressure and has gap underneath), using shorter cutter and with 3 flutes, making sure your clamps all bolted down the way your top right clamp positioned (with the bolt closer to the part to maximize clamping force).
If all of that together does not yield improvement in surface finish, then the machine is also the problem.
It depends on the level of quality you're looking for. If you're ok with what you got in the video then that's all that matters.
@@PaulG.369 Hello Paul. You are obviously right with the router part. This is a hobby level router in the lower price range. Comparing the surface finish to real mills like HAAS or Tormach is obviously not fair and was never our intention. Compared tho other machines in the same price-range the KUBUS Pro ist still the fastest and most sturdy fully enclosed cnc-desktop-router. Of course we could engineer and build a real mill with epoxy-granite base all steel parts, 20kw spindle and Heidenhain controller and get a perfect surface finish but then its not a hobby machine anymore ;) Thanks for your tipps!
@@neno-cnc6841
Yes I'm just too used to full size cnc mills and rigid workholding.
Thank you for the video!
At 4k you could do much better believe me. I designed and built myself a 150kg router that would run circles around that machine for 2.5k... (it's similar to a lagumir mr1 but sturdier). Maybe try cutting costs on software by adopting Linuxcnc. I wouldn't suggest going for a bigger spindle as the machine chassis is already maxed out.
I think you could have more head for improvement with a VMC style desktop mill, but that "already exists" and it's the millennium mill. Again for the cost, there are alternatives unfortunately. Otherwise, it would Be a great machine!
