The chips he shows at 2:26 were not from the machining of the table fixtured in the machine. The chip he picks up are steel chips where the table is cast iron which produces the small chips you see in the background and in the bottom of the machine. No slight against the machines abilities just not an accurate depiction of the process.
I've never seen swarf the size of a Pringles can before. They probably go *Clunk* when they hit the ground. Well, that piece of swarf might just fit in my lathe. I don't know if I have enough swing to clear the runout. Is it thin enough for you to bend by hand? You might be able to flatten it out and use it to patch a dent on your car if you bronze braze it into place.
You don't say "depth of cut of 32 mm on diameter", as DOC is linear measurement and in this example DOC was 16 mm. It is the actual depth you are removing metal. But nice to see some heavy machinery being made :)
When the Rotation Speed and Feedrate are optimized the heat generated comes off in the swarf. You can see the metal chips are blue in colour or 300+ Deg C. Immediately after cutting you could touch the part and the cutting insert and they would be relatively cool. So no need for coolant. Adding coolant can actually destroy the cutting edge as it can cause thermal cracking of the carbide...
@@thundertwonk3553 Hi David. Thank you for the answer (even a year later, it's still valuable). If I may ask further... As the endmill get used, and the cutting flutes start to lose their sharpness, is it normal for the tool then to start getting hotter as it gets more dull? And is colling beneficial at that stage, or would cause more damage? (from thermal shocks).
That guy surely wouldn't be allowed to narrate videos 30 years ago. Back then, narrators must have had good voice, and a look. Our world is fucked up long ago.
Is not 32mm DOC, it is 16mm DOC. DOC is radial.
Ro Cuevas yes. You got that right. 👍

Mine too!

Jaakko Fagerlund you’re right I know them tips are only about 10 to 12 mm square .... 10mm cut in engineering terms
On German Zimmerman machines. LMFAO.
I think the swarf it producing could be easily used as a stock for milling...
Or a coil spring for a Jetta.
Great video. Very well presented.
That swarf is ridiculously humongous. I've never made chips that go "clunk" when they hit the ground !
Jean Roch clunk... ha ha. 👍
Those chips will crush in your steel toe cap boots!
Jean Roch the swarf I make sounds a bit like ammunition or shrapnel. This is when you eventually get it chipping nicely!
And you still got your job...??? 😉👍
@@svogender my job is engineer. I machine only as a hobby, and very small parts.
I worked on a TosKurim lathe in the 1980's. Dont know if it is the same company, but the lathe was a beaut.
Do TOS Vansdorf and Toshulin have the same origin?
good question
*gulp* 32 mm?!? Is that a sandvik insert? Cermet?
Will that fit in my garage? Can I run it off 120?
You have a big Garage @demicron ? ;-)
@@MTDCNC yeah 2 car!
How much cost
Your best option would be to contact the manufacturer
@@MTDCNC gime my WhatsApp number
No coolant needed?
Not needed for roughing steel..
@@sunppaa But needed if finishing? Or still not needed when finishing because it is steel?

@@sunppaa Thanx bro....Soo many dudes do this wrong.... Roughing...Dry.... Finishing...Coolant..!! 👍
I6mm depth of cut, 32 off diameter
Anyway the swarf is 32mm wide!!!!!
@@johnhili8664 No it's 16mm well maybe a bit more because it's a 45 degree cutter but it's not 32mm
@@GeneralG1810 Yes you are right thank you regards from Malta!!!!!!!
@@johnhili8664 Welcome ;D
Either way, it was a decent feed rate and fairly large diameter so shows the machine has the HP!
No safety glasses 🎉🎉🎉
Damn!
I'm can't work I got hit by a chip in the eye ?
No in the groin
as in a fish and chip ;-) or a piece of steel
It's only steel.
Who the fuck are you to say "It's only steel" ??
Done on a German machine. Zimmerman.
Glad you enjoyed the video !
Nice that the Czech people didn't allow to ruin their machine tool industry after the Soviet Union had collapsed!
:)
Pity us Brits did, and we did it 15 years before the Soviet Union collapsed!
Bullshit title = Downvote.

we think he is good looking @baladar and a great voice, the most handsome presenter the industry has
Relax dude
