Pushing DIY CNC to the LIMITS Milling an Aluminum Star 

That was unexpected!... thanks for your honesty. 😊 Looking forward to more. (I mean more videos about your mill, not more crashes!) Liked & Subscribed.

Un ottimo lavoro!!! 👍

Really nice milling 👍

I went beyond the limits and watched it at 2X speed. It was more cool 👍

Really good cam work!

That's a pretty aggressive cut for one of those 24k spindles. Nicely done. You'd do well to get some coolant. Chip evacuation is pretty important

excellent. Colleague👍

Great work :) Did you try the same roughing operation with the finishing tool. Is there more load on the spindle or less?

Nice work! I think you switched Ae and Ap, is that correct?

Where did you buy the DLC coated chip breaking mill?

How much NM(newton force) / Kw of a spindle power as minimum required for steel milling process ? please accurate as possible

Roughing should be described as ae 2 mm and ap 10 mm or am I mistaken? How much ae you took on side finishing? 0,3 mm?

Do you have a link to the 20mm face mill? Thanks!

Nice job, I'm doing similar. Your surface speed on Op1 is a bit too high though, around 603, you should be between 250 and 450 really for roughing aluminium with this style of cutter. From my calculations your op is drawing around 0.91kW. Seems to work pretty well but the spindle is bogging down a bit, the max torque of your spindle is probably lower down in the speed range so I would try figure out where it is and to optimise for that. Try increasing the chipload to something like 0.08mm/tooth and reducing the Vc (surface speed) you should be able to achieve very similar MRR whilst moving the spindle speed down to say, 18000rpm, where it has likely a lot more torque (I calculate 83cm3 MRR with these changes so you don't loose out, really. Where exactly your spindle has its greatest torque is not clear without the spec sheet but it is almost certainly not at full speed) Manufacturer should have a chart. A 6mm cutter with similar settings, and 0.07mm/tooth, should get you to around 63cm3/min with 0.72kW @20krpm. YG1 roughers are similar closer to 0.17mm/tooth but you'd need a bit more horsepower for that. A 6mm YG1 does 117cm3/min but needs 1.34kW. So an example would be (Vc 464, Fz 0.08mm/tooth, RPM 18500, Feed 4440, DOC 10, WOC 1.8 (23%) - MRR 80 to 83cm3/min (ish) - Power 0.91kW

Where did you buy the surfacing tool ?

Where did you get that spindle? also the run time is impresive, mine would have taken something like 3 hours to do that lol

Is there any vacancy in this company ❤

wow, have you done some video on the steel?

What a nice mill ! For the next time, just know that you confused ae and ap 😉

What spindle did you go with?

Эх... Коварную сталь бы показали как обрабатывает или нержавейку какую.

build log/pictures?

What cnc machine are you using?

How much did this machine end up costing to make?

What is that face mill?

Put me to shame with the speed of that second procedure. I’ve got to go play with my speeds and feeds.

Much more rpm, optimal 15-16 thousands

sooo much Vc..... but why? :d

The CAM on this part was mediocre. Too much variable chipload, way too slow.
