I love to watch these video's. I was a CnC machinist for a hydraulics manufacturer for 20 years. I ran there Hard Turn department, all of the parts that I worked on were super small and had to be run to super tight tolerances (one part was +-.000050). We used Hardinge GT lathes and had Epson robots for loading and unloading of parts. We had to use diamond inserts because we did finish machining of the heat treaded parts. Most of the parts we were making a seating area or a bore that have to last over 1,000,000 cycles before we can even sell them. Most of the parts were run in under 1 minute with loading and unloading with the robots. With that setup I ran 4 lathes at a time. I love watching the other side of machining, the size of the parts that you work on always make me laugh, to me they seem so big to be almost comical.
Buongiorno MAESTRO CHRIS. Complimenti per il tuo video, e ADORO l' operazione di FRESATURA per fare il dado. Ho sempre amato la fresatrice. Ciao 1️⃣1️⃣1️⃣1️⃣🔝🔝🔝🔝🔝🔝🔝🔝🤗🤗🤗🤗🤗🤗🤗🤗🤗🙋♂️🙋♂️🙋♂️🙋♂️🙋♂️🙋♂️🙋♂️
I have to agree with certain comments.. that is absolutely remarkable! Thank you again for the beautiful work you do Chris! Thank you man, it's awesome!
Amazing finish on these as usual, button tools are a bit of a challenge but because of the round shape they are subject to chip thinning so in order to maintain the correct chip thickness to use the chipbreaker the feedrate needs to be a lot higher. I'm sure you've tried it before and you've got a process that works well as it is! For others who read this there's a lot of literature on sandvik coromant website which explains this, and for those who are inclined there is a formula which can be used to determine the chip thickness
I did try it and I think the problem was that the tool was sticking out over 2.5" (64 mm) and I could not plunge the tool deep enough to break the chip without chatter. But as you said, if you have a rigid setup they work really well. Thanks for watching. Chris.
@@ChrisMaj yes a setup that isn't stiff enough to handle the pushing isn't helpful, have you tried the round inserts in a shorter holder for removing bulk material from the OD? I'd imagine you'd be able to get pretty impressive results on parts where you're taking a lot of material out
Bronze is very tough to machine in production. Great job. I am starting a machine shop with my father. We want to focus on turning only. At what point do you decide to put something on the VTL vs. a horizontal Lathe? Is it diameter of chuck or simply length of part? Or perhaps rigidity considerations. Most likely we will start with a vertical but I would love to be able to convince the investors of a VTL. Let me know your thoughts.
Oh I was also going to comment have you ever used a peck cycle? Try it with the round insert and slow your rpm down, it will break the chips great I used to do it with a 1 inch round grooving tool for big flanges
I'm assuming you are talking about chuck jaws pressure? It's a 4-jaw independent chuck. The OD wasn't that critical and the jaws don't really leave any marks.
I tried 0.25" grooving tool, but with 2.50" stick out the tool snapped in half. I've also tried round insert but for that you need high feed and deep cuts in order to break the chips. With my setup and the depth I needed to do just didn't work.

That bronze looked nasty before turning. The music selection was spot on.
#goodtimes
I miss machining aluminum bronze . It hurt so bad on the manual but it was so easy to hold tight tolerances and such a nice finish
Marine props?
Al bronze, Phosphor bronze & stainless for props as l remember.
Ten detal waży więcej niż wszystkie, które zrobiłem przez ostatni miesiąc 😅
Zabrał byś się za konkretną robotę a nie jakieś małe pierdoły. 😉

Always a pleasure watching the creation of something out of nothing. Great job! :o)
Respect.
Thank you Chris.

Thank you man, it's awesome!
Some swarf re-direction can make life a lot better....Great video!
I remember the thread on reddit and I am still shaking my head at the groove tool and round button tool suggestions.
You do very nice work. It's a pleasure to watch your videos, keep them coming ! :)
Chris that is some great work

precisely, with a suitable combination of speed, feed, chip depth and the shape of the shaper on the blade, it works almost miracles
excellent jobs👌 and well filmed mate thanks for sharing 👍
Great work, thanks for sharing 👌👍
very good job chris
Cool work. Job
Nice work. Thanks.
Best machining video's in the world.
I don't know about that, but thank you.
@@ChrisMaj It could do with you saying something once in a blue moon....lol
@@theessexhunter1305 I'm the shy one 🤗
@@ChrisMaj Ok you win, take care and enjoy what is left of the weekend.
hi to pierwsze to duża i ciężka szpulka na nici.
pozdrawiam Jacek.
I love watching your videos can you make a long video 🎉
milo sie oglada

Nice :) #DuplexCNC

It all depends what kind of work you want to do. Are we talking few pounds or a thousands of pounds.
That bushing was so small I feel like you could have used your little CNC lathe.
Oh I was also going to comment have you ever used a peck cycle? Try it with the round insert and slow your rpm down, it will break the chips great I used to do it with a 1 inch round grooving tool for big flanges
Very nice.
Didn't you flipped the bronze bushings too many times?
Rough and finish
What is your machine pressure are you using to hold the finished side with hard jaws?
I'm assuming you are talking about chuck jaws pressure? It's a 4-jaw independent chuck. The OD wasn't that critical and the jaws don't really leave any marks.
is that clamp just used for more rigidity and stability?
I think to prevent it pulling out of the jaws since its quite tall and heavy
@@thedutchgamerguy8580 ahhh gotcha gotcha, yeah I wouldn't want that part coming out haha
what is the groove in the holder at 13:20 for?
11:52 Is that a custom boring bar? It seems like the top of it isn't flat. For coolant?
It's an old beat up boring bar we had for years. The top was machined so it fits in our smaller lathe.
Here from Brazil. What is the sound track?
Random TH-cam music.
what are the wheels for?
A crane that moves on tracks (like at ports for moving containers) perhaps.
What feed and speed and what are you trying to groove with
I tried 0.25" grooving tool, but with 2.50" stick out the tool snapped in half. I've also tried round insert but for that you need high feed and deep cuts in order to break the chips. With my setup and the depth I needed to do just didn't work.
Try pecking about .1 in x with a fair feed
@@tuckerhardin1116 that would take forever bro just use a different tool lmao there’s always other ways
What state ?
Nie możesz spać? Dopiero 6 rano 😁
U nas dopiero 11:00 wieczór.
how long did it take
It doesn't matter how fast you do it, they will always tell you took too long to finish that job.
@@ChrisMaj so true man, most annoying thing. You do it to the best of your abilities and it takes as long as it takes
Złote a skromne 😂
Well you wouldn't have got all that done in 1 week Chris.A lot of machining in that job.
