PLG-42XL Gang-Tool Lathe with 6" Chuck

[Amel3]

u should turn this chuck in debth u2.5 and no constante rpm

i think this is waste of time

[Metalloys]

It's so boring watching all those CNC Lathe demos eating up stock and wasting huge amounts of material, whilst the action itself is so mundane and drab and does not really show anything ...

[thierryxxthierry]

@Metalloys it isnt getting wasted mostly not

[FlipCurse]

that is some serious machine equiptment

[tonyclifton58]

The material is most certainly aluminium. They are probably using the g70 series cycles. That would explain using a vnmg for the roughing so they could get into the undercut. The program would have run more efficiently if it was written using no cycles and using a cnmg for most of the roughing. The depth of cut could have been tripled.

[lessirkilion]

yah with cnmg they could have taken .500 right off the OD in one shot at F0.020, it would have taken at least 45 seconds off the run time for that tool. still thats a great machine. i wish we had machines like that were i work. we hava non geometry nakamuras that are over 20 years old. we dont use new inserts anymore either. i have to regrind them on grinding wheels so that they are useable again.

@lessirkilion

Yeah i think so too.

With aluminium you can have very good survaces, but not as shiny as this one.

[lessirkilion]

by the way. i work with 304 everyday. i also work with aluminum. when i cut with no coolant the chips come off a nice golden brown color. that looks and sounds like aluminum to me. not steel

[lessirkilion]

nice clean machine. looks like it hasnt seen coolant in its life. very nice profile cuts tool was perfectly on center. proper speeds and feeds. debth of cut could have been better but becuase the rougher was used to finish all in one shot it makes since to save tool life for the tool path. personally i would have used u.200 in a g71 line or D2000. depends on machine i guess. and call up a new tool to finish.. the tech did a good job though. was g71 used to step the turn or was G01 Z- used?

[bastian4434]

wtf no mashiene are so clean like that one, i think fresh buyed for the find :P

silent machiene

Whats with the kindergarden cuts their taking?

[JTMarlin8]

"Kindergarten" cuts for two reasons:

1. V shaped insert required for the 45 degree ramp down = much shallower cuts than with D and C inserts.

2. No coolant while cutting aluminum = lower SFMs. 

and probably...

3. Crappy machine, lol

[cumulo25]

it's aluminum

[Emyemgaa]

This is not Steele thats Alloy you can see it on the chips an hear the cutting... sound...

[protozyko]

Nice video but i would rather use a bigger nose radius for roughing then that small for finish, take bigger cuts dude, those tools is made for max 5 mm radius cut.

[mwhiggs]

nice..could of made cycle time faster though..good demo!!!

[LokiandNaic]

wow... oh my GOD!

very good... mechanic is very beautiful!

[dinker12345]

What kind of inset was that??? It looked like either a cermet or a cbn diamond tip

[JTMarlin8]

Actually it looks like plain uncoated carbide, which is pretty much the standard for aluminum cutting.

Cermet and CBN are for steels. Diamond is PCD, probably too expensive to use for a simple demo (though they can be had for cheap on fleabay).

[0oz3r0o0]

Very nice,,and that thing is really hot after the work without water :D

[pm400]

superb...NO COMMENTS

[berry506]

very clean might have used a roughing tools for some of those passes but it works.

[65triumphrider]

Nice.
