Especially liked seeing the blocks machined on the lathe head to get a true part, fixturing is half the job.

What a beast of a lathe! I didn’t realize a brake rotor would ever be made out of 1045, I assumed something much harder…

Must be for a German/Austrian or Swiss machine. 😆 Beautiful turning job, as always Chris. Thanks for another excellent video.

Remarkable to see a brake rotor in mild steel. I thought cast iron was pretty much required because of the wear and friction characteristics. Well it's an industrial application so it is probably used differently from a vehicle brake.

Interesting to hear the rotational speed change to keep the cutting speed constant.

I can only imagine the motorcycle that's going on! Yes, yes, winch drum or something, I know.

Came out well 👌 nice bit of turning thanks for sharing 👍

Nice work Chris. Thanks for video.

Nice job Chris, ..........for those that don't know, thats a tricky one to get right so you have to know what you're doing

Then Chris is the right man for the job! 🙂

383 pounds of chips at , what $.05 per pound? That would be $19.15 in beer money for someone.

That's a cool lathe you have. What's your favorite lathe in your shop?

Nice work!

I'm guessing the keyway was chosen over a spline for much the same reason 1045 was chosen? Beautiful work anywhos!

Hi Chris, I am interested why you choose X direction raw then Z direction in this particular job?

Keşke daha çok ve uzun olsa ama bu işin zor olduğunu biliyorum teşekkürler bunu bizlere gösterdiğiniz için

A lot of young machinists will not understand cutting the final surface twice. The results turned out great.

Just to clarify, are you saying a spring pass or 2 final depth cuts?

​@@kestes292I don't agree with you 100%, I agree with you when it comes to shafts where a lot of material is removed or thin-walled rings or workpieces made of bronze or tempered steel. However, as I see the drawing, it doesn't really have any critical tolerances except for the 70K7. As far as I'm concerned, the 3 clamping is not necessary. Ultimately, however, I say that every mechanic has to stand behind his actions, I think there is no right or wrong

If some young machinists doesn’t understand it, it’s most likely because the “experienced” machinists didn’t educate them properly.

SWEET!!

That's a lot of barrels of chips for a 1/2" brake disk!

Hello, excellent video. What is the total machining time for this part? How many kg per hour can a lathe remove material (an average)?

Nice work ! For my bike ? Many thanks xris

In measuring the inner diameter, typically only the front part is measured i think dont you care about taper?

0:19 - Nothing hard for you. The dims suggest there isn't a lot of energy to dissipate, or there's a lot of cooling available.

I'd bet money that's going to be out of square. Ideally you'd machine the largest diameter and face. Mount the part in machined soft jaws to suit, finish the rest of the part.

Over head crane brake Chris?

That's what I'm thinking too. Seems about the right dimensions. We've changed several of our cranes over to disc as opposed to drum in the last few years where I work. So far they've been relatively lower maintenance and seem to perform the same.

🤩🤩🤩👏👏👏👏

Brah.. where's your slots and cross drill? Do you even brake brah?

Crazy how much of that had to be turned into chips!

Rotor in America not disk

@lancer2204

Well the plans are German and in sensible units, so... disk.

I live in America and here in my country this is a disk. Maybe in the USA you have another name for this product, but in the USA everything is wrong. By the way, stop calling yourself an American, that's ridiculous. Just to explain for those who don't understand geography: America is a continent. Some people with low education think that American is a nationality, but this is the same as thinking that European or Asian are also nationalities.

Here in the USA part of America I'd call this a brake disk. Some people would also call it a rotor, but just like there is more than one thing that is a disk, there is more than one thing that is a rotor. People working with these things (at least in the USA) should recognize both terms.

Everyone that I have ever had any discussion about brakes with - in the USA - uses those two terms interchangeably and doesn't care. It's no different than people calling wheels rims. Even though the alternate words aren't necessarily accurate, everybody knows what you mean when you say them.

Bremscheibe ?? Ah so - ja, genau - jetzt ist billigisch to make Teile in Amerika, richt? ;-)
