OMG!!

wow that was fast

[sietevicio]

ooo

[weskoki]

Great you made sardine can!

[jewsh666]

How many ipm is that? That mill is flyin'

[Snooky0901]

ja toll als cnc fräser weis man ja wohl das man a) nich mit so ner geschw. fährt und b) man vielleicht die kühlung anschalten sollte, verdammte messevideos wo alle nur aufmerksamkeit wollen ...

[ChrisRiley93]

That was really awesome. Was it sped up at all?

[zaknefain100]

Experts or not, there's obviously an issue with this cut and you only need turn up the volume (slightly) to hear it. I've personally used Fraisa and they make a great product. I don't think the cutter is the culprit but most likely, the tool holder. Another way to get corner-chatter out of a pocketing op, especially one in aluminum, is to simply use an axial step-over of at least 75%. You can still match the MRR, even with a reduction in sfm... not that one is usually needed.

que ansia y que prisas!!! jajajaja

[Landsknecht89]

das allerbeste an der Geschwindigkeit ist ,.......

dass die Unfälle verheerender sind.

[wurschtbrot123]

@Landsknecht89 aber nur wenn mans gleich beim ersten mal so schnell abfährt;)

[AsKInsani7y]

@Landsknecht89

Und bei solchen Schnittwerten wie in den Videos hat man eine Standzeit von 5 Minuten^^

[MrDhcracker]

lol did you have to pay for that bit?

nice work!

question, where are good places to order aluminum blocks from? i'm looking for marine grade aluminum block for my first project, but finding it more difficult than it should be using google to find supply houses.

i agree with not needing coolant all the time, sometimes all you need is some air to clear the savings out of the way, and a lot of inserts are designed to absorb heat meaning cooling them down whilst cutting will only make them brittle and break easier. nice vid, the way a person programs is akin to how one would paint a picture

[floringguy]

i just would like my router mill wood with this speed... it awsome...

really miracolous without coolant... but it works...

[freefall4fun99]

you again? Spammer. Listen dude, coolant is last week's news. With the technology of modern cutting tools, you don't need 1000psi coolant. Talk to some tooling experts and they will set you straight. In the meantime...quit spamming all these great you tube videos

[dooittoit]

What is up with all these supposed "expert" machinists that reply on youtube? Are they all still in tech school believing what their instructer says as the gospel? Ragnarlava, how would you improve the programming?

[wccti]

He was probably talking about a finish cut, lack thereof.

[szelag]

dooittoit -

From the look and sound of it, that pocketing toolpath makes sharp 90 degree movement changes at the corners. Can hear the tool chattering as the chipload changes. There are HSM pocketing toolpaths that use much "smoother" large radius movements (or troichoidal milling) to prevent this. Same reason why for high speeds it's good to use a finish tool that's a good bit smaller than the minimum interior radius.

[dooittoit]

The HSM features would be a product of the CAM system used, not the product of a programmer who was inept. The CAM software I run does include troichodial cutter path features, but in a pocket such as this one, would take longer to run. Now if you give me "Volumill" as an add-on it "might" be different. All I am saying is that there are too many armchair experts who find fault in these videos showing some great machining. Also, HSM does not necessarily equal a higher material removal rate.

[ragnarlava]

Nice feedrate, bad programing though.

[freefall4fun99]

uummm.... how would you program it differently. Seems like pretty good MMR to me.

Holy CNC Machining Batman

[sleeper142]

3/8" endmill? DOC? Spindle rpm? IPM?

[kamikim1]

i belong to this proffesion ,

great machining
