Great Video! One question, why does it have to be grinded for threading? Newbie out here, sorry

Very nice. If you could, can you post roughly what the raw materials cost in your videos? I think a lot of folks would be surprised. That piece you worked on is what, $5K + shipping?

I don't have anything to do with ordering materials, so I don't really know the cost.

@@ChrisMaj Today I found out that my company prefers to lose jobs and customers than to fill me in on the job information. I am the only one in there with machining knowledge they try yo economically challenge every single step I take and they won't even tell me how many parts they are expecting. That way I never know how much time to devote to developping a mass production process and I end up giving machining times for flipping a 10 second part around 3 times myself. Also they have been sourcing materials and tools for 30+ years and have spent millions on them and even my single occasion suppliers almost halved the prices they were getting. I feel bad for even telling them when they asked me. Talk about a toxic relationship.

That's awesome!! I run D2 for the most part (making pulverizer blades) in a mori seiki vl553 with live tooling. The roughing inserts last nearly the whole job. The finishers last around 8 parts. Cnmg 643 and 543 for roughing, and cnmg 433 for finishing. All Sandvik brand. They take some abuse! Thank you for making this content!!

So you ignored the fact that its running a program? It's a chuck, a fixture device and the 4 post is rigid, turrets are just an extra. This machine is producing amazing components and you don't even see it as a CNC.

Chyba jeszcze nie było na niej tak takiego ciężkiego detalu, dlatego pytam czy maszyna mniej więcej da radę - chociaż moment obrotowy na przekładni też ma znaczenie.

@@MichałSt_PL Na mojej tokarce zauważyłem że to średnica bardziej daje wycisk jak waga detalu. O wiele lżej jest obrabiać sztukę o średnicy 200mm x 3 metry niż 600mm x metr chyba że maszyna ma naprawdę niskie przełożenia.

How many button pushers could make this manually from start to finish, no digital readouts, manual machines only, including key ways, drilled and tapped holes, threading, etc, and be able to hold tight tolerances and pass inspection! 😎If you think you have what it takes speak up 😁
