Peter, I know you're art a point in your life where you don't have to work, and definitely don't have to mess around with this TH-cam nonsense. (At least not for the monetary gains.) But I appreciate all you do for the community. Thank you.
17:30 Thank you so much for documenting your crash. I teach machining and it’s a huge relief to be reminded of just how many things a machinist has to pay attention to. It’s a hard concept to understand that very little a machinist does is ground breaking: What a machinist does is stack things up higher than most other people. This and this and this and this and this and this and this and this and this is what makes a good part...
Yes! Du to computers and design software things have gotten more complicated. On CNC machines like this there are many operations, tools and dimensions to keep track of. Any lack of concentration or interruption can cause a mistake. Just the making of videos and adding the camera work has caught me a few times. No matter how good or experienced you become you will make mistakes. Anyone that says different is lying.
Oofdah! I cried a lil bit inside. Thanks for sharing the f#ck up and not editing it out. I always appreciate it when yall show the nitty grit of it all. Even the pros.... And like always, every single video, I'm learning. Thank you so much.
Peter is Human, a very very intelligent and thoughtful human that was kind enough to include a spindle crash for all of us to learn from, thank you! Also I'm amazed at the finish after the somewhat aggressive cut at 22:00. At first I thought the spindle wasn't able to keep up, but compared to the clean up cut at 22:30 it was just the variable spindle RPM vs Tool radius I heard. Simply awesome machine!
I certainly hope you have squared things with the customer so this set of videos doesnt get removed like the previous one. Thanks for sharing, great to learn from. Charles
Thanks for for your recent response to my request for some insight on where to start. Your last video was very helpful to me. Please drop me a line when you have some time. I truly benefit from your methodology. You are quite the inventor.
This guy is a very very good at what he does .. it’s all in the details all the little stuff can let you k is how good someone is.. I’ve been a manual machinist some cnc it much ..
Thanks again for showing the near crash! I'm glad for you that you could essentiellt buff it out. Dunt want to think about what a spindle job would cost on that machine...
Looks like a mirror image of the previous part, if you had known about this one maybe you could have put the pins in symmetrical locations and just been able to flip the plates. Beautiful work as always.
A shame you couldn't use the original guides but still nice watching the new one get made. Keeping stuff from wondering on long lengths like that is challenging.
Be aware im a great fan from both worlds and also that old one. Merry x mas - I enjoy it all - No doubt man.. you are a good craftman. 5 stars from old to new world ( give regards to Werner B .. he moved to the new world too ... ) im looking forward to when that day comes that reactor drives the us to a moonar landing.
@@mannycalavera121 he crashed the spindle into the jaws, just minor but we still consider that a crash. Just like in real cars, we don't want to touch anybody else's car with our own we don't want any part of the machine to tough another.
Gee, left and right handed parts. I have to wonder if they changed that keyway location specifically because you had posted videos showing their previous part being made. :-)
How quickly do you need it, and how many downstream changes would be needed to improve the manufacturing? If you make a million, that's all where it's at. If you're making ten, sending more money to Peter might be the right trade off!
Hi Peter, I'm wondering if someone makes CNMG tools that let you tip the head at 30 or 45 degrees for OD turning? If not, maybe you could machine a custom holder and make a video of it? Seems like it is a real pain to turn up close to the chuck with the head at 0 degrees, with the head at an angle you should have a lot more clearance. Glad it was a minor bump and not a major crash, thanks for another great video!
Yes Sandvik does make some. I do have on for a CNMG insert that runs with the B axis at 45 degrees. But I don't have one for my finish tool. So even if I could rough there would still be a problem (in this case) with my finish tool. This also doesn't really help for milling. So you still run into the same problem with milling tools.
I would consider that just a little “interference rub”. A crash is when the machine has to be realigned IMO. Although if a rookie was running it and didn’t stop it, it would’ve been much worse. I’ve seen some bad ones over the years...lol.
You saw it if you pause the video and read the mic. .010-.012" on the diameter. In this heat treated material that's enough to get a good finish. In softer steel I would leave more. Say around twice this amount. So if you are sneaking up on a dimension and want a good finish (in soft steel) leave about .030-.040" with the roughing and take a first finish of around .010" more on the diameter to establish your tools setting. Mic the part and change your offset for the finish size in one cut. Once you establish your setting move you rougher in on the next part to leave enough for the single finish pass with a good finish. You will, if you take a second small finish pass in mild steel ruin the finish. Unless you can run a much higher surface speed. So if you find you have to, speed up the RPM (or surface speed).
Yes I do have one for the CNMG tool but not for my finish tool. So it would have the same problem. This is good for turning but doesn't help for milling tools.
@@EdgePrecision they also have them for VNMG and VCMT tools aswell. Yea milling is an issue. I run a Mori Seiki NT 4250 which is similar to your Intergrex. I find shrink fit holders really help with the extended reach that's required.
Hi Peter, in previous vids you asked for noobie questions, here's one. I have zero experience on my bridgeport with flood coolant. I never see you clean the parts other than blowing a hole out or something. I would think even water soluble coolant needs a rinse, esp if there is any lubricating value helping the cutting and finish. Done parts seem to come out spotless and ready to go...?
Generally for parts I'm using for tooling. I just blow them off and wipe with a rag. That's good enough. But the parts that go to my customer are deburred and cleaned in a part washer. Certain coolants or oils can corrode/stain some materials so they do need to be washed off. Molydee oil for instance can stain some materials. I have had this happen when using it to tap beryllium copper. Some synthetic coolants can cause corrosion on some materials. I don't think it's the coolant itself but it cleans off any oil residues that are protecting the metal from corrosion.
@@EdgePrecision Ok, thanks for reply. I decided to buy a mill one day and started making chips. I thought I would make some easy parts for the hot rods I work on and build, and it is not as easy as you make it look! It is hard to be precise, so kudos and thanks for the great vids too, learning a ton.
Too bad about the crash with the chuck jaw but at least you caught it when you did in the cycle. You mention using Starrett ground flat stock, are these guides going to be heat treated?
The mounted it so high on this machine it’s difficult to use. I prefer to touch off the tool this way I get a confirmation on the position on the display.
Hey Peter! Sorry about the light crash but, was wondering something, knowing that you run Esprit. Is there a reason that you dont model your chucks and jaws in Esprit and run simulation? I know that you make a lot of custom jaws but, for someone like you, it wont actually take much time to model them, even as basic rectangular boxes and save yourself some headaches? You are a great machinist, best of luck!
The program in this video was made with no simulation. I have just recently started using the latest version Esprit TNG. In that version you have to have a model of your machine and use the simulation. You cant process code without first selecting a model and part setup in that model for simulation. The will provide you a accurate model of the machines you use for this process. This is absolutely the most accurate simulation I have used. Not only is the machine and all its components taken into account travel ranges of all axis but even the tools holders shanks of any kind and fixturing of any kind. You can model you own fixture with moving jaws spindles . Steady rest with moving jaws everything.
@@EdgePrecision yep, absolutely. Thats why I asked. Im a TNG user as well and with our machine we always use simulation and its not bad, it actually a must for complex parts with custom tooling.
For stuff like this it's a bit harder but I always SIM before running a program ujnless it's miles away from the chuck. Takes time, totally understand why would wouldn't bother for this, but mymillturn is 550k, I'm not risking that for 15mins programming time :)
It's up to you. I just find that the simulation is good if everything that's defined in the cam software is exactly (and I mean exactly) the same as the machines setup. Even if its off (as in this case) a very little bit it does no good. It far better to just pay attention when you run the first setup. Witch in this case I didn't do. I normally watch this very carefully, because I know its a problem with this machine.
@@EdgePrecision totally, not throwing shade. Even with SIM I'm still keeping a close eye on first off runs. Everything has to be on point Becuse it's quite often clearances are so very tight. He'll, even the DMG tech scrubbed the spindle face on my brand new machine, ironically while setting the collision detection lol.
If everything is defined properly and the safety work zones are enabled. Yes but it is a lot of work to keep changing the settings. If they would have a way to save different setups for different safety zones I would use it more. Otherwise I turn them off. And pay attention to what I’m doing. I should have been paying more attention to what I was doing. Instead of video production.
Sorry about the milling spindle faceplate. Just the other day i almost went 4" and 8" too deep on certain elements on a part, needless to say i almost blew the part , the tool , the toolholder , the fixture ... No better coffein exists than a 'whoopsie' . (maybe you should invest in 2 extended holders for the fixtures&small stuff . Probably you could use your 570-3C bars in o.d. turning orientation . Just a tought . )
I'm curious if the high pressure coolant flowing through the hole in the gun drill can cause mild deflection that could cause the drill to drill a slightly oversized hole?
No the idea is the drill's tip lands ride on the film of coolant. This is why oil works better than water based coolant for gun drilling. So volume of coolant is better than pressure for larger drills. You need to maintain the coolant film. Sort off like a main bearing on a engine's crankshaft.
I usually us a spherical carbide burr with a 6" long shank. This can work where a c-sink can't reach if you have to come in at a angle. Just don't run it fast. And if using at a angle be careful it can ride up out of the hole and skate across the part. If you kind of pulse the drill it works good. It will chatter if run to fast.
It varies depending on the tool and its use. If I remember this piece was 4145 steel with a commercial heat treat. So that would probably make it around 34-36 Rc or 320-340 Brinell hardness. The drill guide plates function fine at the unhardened state of the Starrett ground flat stock.
Thanks for the explanation. I thought they may have been a bit more harder in Rc. You said it was getting cold there. Does working in hot temp have much affect on machine wear that you know of.
On machine wear, no I don’t think so. It can make a difference if it was hot one day and cold the next day on the position of the machine. Some machines have temperature compensation. The Mazak has liquid cooled lead screws.
Just publishing the video. It depends on where in the world you are. I usually work from about 12 hours during the day. From seven am to seven pm. So I publish videos after work most of the time.
Was it the engineer or the american ( New world ) craftman which fell and hit his head down in Charlestown? .. ? ehh.. when whill that nuke reactor be ready for testing??
Yes this solves the turning clearance problem. But not for milling tools. I do have a tool for the CNMG insert but not for my finishing tools insert. I tend to use the other tools because you can't use those 45 tools with the tail stock. Unless you put an extension on them. But in this case they would have worked.
@@westervonburgermeister9877 I think Aaron was referencing the engineer that designed it. I've made oil and gas parts that were quite complex, and then been shown where they were going....

The machine is running in constant surface footage mode (G96). So as the diameter changes the speed changes to maintain a constant surface speed.

What is that deburr tool you used your cordless drill on those holes? Looked like a ball end
I usually us a spherical carbide burr with a 6" long shank. This can work where a c-sink can't reach if you have to come in at a angle. Just don't run it fast. And if using at a angle be careful it can ride up out of the hole and skate across the part. If you kind of pulse the drill it works good. It will chatter if run to fast.
What is the heat treated material you use sometimes for making tools? I have never seen that before. Thanks for the video
It varies depending on the tool and its use. If I remember this piece was 4145 steel with a commercial heat treat. So that would probably make it around 34-36 Rc or 320-340 Brinell hardness. The drill guide plates function fine at the unhardened state of the Starrett ground flat stock.

This machines turning spindle can only turn a maximum of 1600 rpm. Not enough to worry about for this chuck.

you can next time use tool , that your machine head is like 45° , so you have more space for safety
Yes this solves the turning clearance problem. But not for milling tools. I do have a tool for the CNMG insert but not for my finishing tools insert.
