too much rpm not enough chip load looks like high speed not carbide mill will start to rub not cut ...hss tool sfm 800 carbide 2000 for aluminum...chip load per tooth hss .004 carbide .008...if you watch the video you see a big burr, tool is rubbing not cutting...need coolant, climb cut and step over 75% dia of tool per pass
as I already said 10000 times... this was a first try.. the mill is not for aluminium but the only one i owned, more speed was not possible at that testing time....
not talking more rpm neeed more chip load per tooth to make tools last if its not rigid enough you cant do it but i do understand first try, not for aluminium, !!!!!awesome build!!!! you workin on your steel machine?
das waren die ersten versuche ob die Achsen funktionieren, ob die Spindel funktioniert usw. Da hatte ich noch keine ahnung von g-codes oder dem unterschied von gleich- und gegenlauf.
@wuselrob das sollte man aber bevor man so eine Maschine bedient. Bei CNC Fräsmaschienen ist es inzwischen doch egal gegen oder gleichlauf durch die Kugelumlaufspindel also viel spass mfg
ich weiß nicht wie oft ich es noch sagen soll, das ist der aller erste test während die maschine noch im bau war. da fräs ich doch nicht mit 3000mm/min ;)
das war wie gesagt mein erster Test ;-) Habe bis dato noch an keiner CNC gearbeitet, geschweige denn G-Code geschrieben. Mittlerweile bin ich schon recht fit.
This was my first try with my cnc. Before that, i never had contact with cnc milling or writing g-code programs..
If I had built that and it took 6 mins to cut a hole that size, I really wouldn't care, its one hell of an achievement and better thand doing it by hand or paying a fortune for someone else to do it. I like watching it anyway....
If you do helical cuts rather than steps then the process is much faster. More heat, but MUCH faster and even with the heat a quick blip of WD-40 evey 10 seconds or so keeps the temps in check.
maybe you didn't read the title... that was a first test of a self built cnc milling machine.. it's an aluminium machine... i have a diary of the building process on my website.

fürs erste Mal in Alu fräsen sieht das Ergebnis doch ganz gut aus! Und die Geschwindigkeit ist auch nicht zu langsam, da es ja kein BAZ ist!

conventional cutting on a cnc looks painful to watch. try a g3 and climb cut

what kind of cutting tool are you using?
orionstarman 3 years ago
top tips......
use a larger cutter...
slow down your plunging feed...
use coolant ...
and climb mill ! you could have cut that hole in less than 30 seconds !
andy1672 3 years ago
sburrous is right you should climb cut that, you finish will be better & your tools will last longer, so coolant would help too.

why did it take so long to make that hole, i saw a machine 20 years ago make a bigger hole in 5 seconds

Looks like a bearing holder.. perhaps you are building another CNC machine? :)

yes it looks like but it isn't :)
its only a small hole in aluminium.
My next machine will be a steel-machine. but first i have to bring this machine to completion :)
