Very nicely done
Enough chips off this to make a new engine block. Well done!
Now that is one hell of an indexable drill!
One heck of a billet there.
We could use that kind of drill 😀 nice video man, im definitely watching more videos of you
Wow!
Thanks for sharing 🇨🇦
Damn bro....nice work, looks amazin
Another great video! What are those stackable black cylinders for the work holding in the first operation called?
Now _that's_ a big drill.
Very good!👍
Thanks!
Amazing work and video.
Thank you😀
Very nice job it looks like a very nice trophy,😅. What are the tolerances?
Amazing James, question, how long did it take from start to finish?
I couldn't time it because I was busy doing other things. Sorry.
What kind of coolant is that?
Bit worrying turning that undercut, need your retract to be correct
At 4:52 and 5:39. How much harmonics are you getting. Can you use you use an empty tool position away from the work face to mount an antiharmonic block. A block filled with steel shot with an adjustable depth filler plug that might have a belville washer to change the compressive force on the steel shot to change the tuning . Or cut the outer detail before removing the inner so you don't end up with a wine glass vibrating. One could place a screwjack inside the piece with rubber pads to dampin the wine glass harmonics when cutting the outer relif. I always worry about the harmonics damaging spindle bearings .
Oh, that would be a good idea! Thank you for sharing your knowledge.😃
That's a lot of material removal.
How long was the processing time?
I don't know because I haven't measured it. But it took a long time.
As for vibration, have you tried wrapping lead straps around the tool body?
I haven't. Is that much better?
Great job James! What was the rough diameter and weight of the piece before machining?
It is about 530 mm in diameter and weighs about 1 ton. Thank you!😃
@@jamespark_85machiningtv ...??! At 0:12 and 0:17 one can clearly see 560 mm length, 640 mm diameter. It works to about 1.4 metric ton or 1400 kg (assuming 7.8 g/cm3 density of carbon steel).
Now, I got sort of used to questions like this one here, where dimensions are clearly shown in the video and then someone asks "how long this thing is?" - but the OPERATOR not knowing what he is working with? That's surely quite another level... ;-)
The color of the coolant looks like it is straight out of the Simpsons.
Fluorescein.
Interresting video, thanks for sharing :)
Any particular reason the forged blank wasent forged with a hole in the center to lessen the amount of machining needed? I know they can relatively easily press a hole through the middle when forging.
the block could have been forged before the product was ordered
What’s it for? Great vlog 😊
This is a nuclear power plant water valve body.
1500kg of en26?
It's machining great, but what's the seeming problem?
There is no particular problem.
80 minutes just to drill that initial hole.
What was the process time for the finished product?
It took a long time to process a large amount. I didn't measure the time exactly.
what name of machining center where first 125 mm drill was made ?
Called TMAX Drill, the product I used was made by a company called New Tech in S.Korea 😀
@@jamespark_85machiningtv TMAX ? Is it drilling tool? Or CNC machine ? I was asking about machine. Looks like one of Fritz Werner's..
