Thank you for sharing your wealth of knowledge with us. I recently started my second year of tech school and I love it. I've even started recording some of the parts that I make.
Peter- do you think it's a good idea to literally machine a .375" thick bar (9" long by 1.5" wide) out of a 1.75" round bar of Nitronic 60 since i couldn't find a flat bar i had to buy round stock and machine it down what do you think is gonna happen by the time i get close to the rectangle? is it gonna warp? i hear it's tough to machine too
We do that kind of thing all the time. It should stay pretty straight if you take the same amount of material off all the sides. In other words try to keep the flat bar centered in the stock with in reason. That way any stress that in in the bar is more or less balanced.
@@EdgePrecision actually it wasn’t bad at all nice shavings at the end .01 DOC ! that kept it from moving very nice material and I used YG drill bits too
First time machining nitronic 60 this upcoming week. Thanks for the share. Any tribal knowledge is welcome. I know I need to be aware of its work hardening. But I'll just have to find out how the chips sling.
I made this video a very long tome ago. I don't think I ran these parts without coolant. I can't exactly remember the material. Some kind of stainless or Nitronic 50 maybe. Anyway none of that could run very long without coolant. I probably turned off the coolant when making the video clips. Unless you are referring to the feedmilling cutter. That I ran with thru the spindle air on the cutter. The tool was a 3.0" Tungaloy FeedMill with a SQMU1206ZSR-MJ Grade AH130 Insert.
How did you mill the rounds with the tip cutter? in the program it looks like you were milling on centre with a rotating c axis? did you have to offset the cutter to get it cutting on the edge?
I think you are referring to the feedmill roughing the neck down. In this program i am off center by the radius of the tool. I know it doesn't look that way. You have to move off center using a facemill type of tool because it because doesn't cut on center. Even if the tool cuts on center it is advisable to move over the radius ( in Y) of the tool or you will be cutting as if your plunge milling because the stock is rotating into the face of the tool.
Thanks, if you are roughing off centre then you'll be leaving an an arc on either side of the cutter. How do you go about finishing something like this to avoid that?
In this case after roughing the bulk of the stock with the milling cutter than I went in with a turning tool for the remainder of the material to rough off. The reason for the milling at all is the intermittent cut for the turning tool. It would be possible to just turn it off but it would take a very long time and use a lot of inserts. This material is Nitronic 50. Turning tools in this material don't like intermittent cuts. So even though the face mill leaves radius's they aren't a intermittent cut for the turning tools to remove. Hope that makes some sense.
The chuck I use most of the time on the Mazak is a 16 -1/2” four jaw manual chuck. This type of machine if you use a large diameter chuck it causes a lot of tooling interference problems. With the B axis at 90 degrees (milling and Turing on the OD) you need long tools if your part is a small diameter. The spindle face is 12” in diameter so when your close up to the chuck this comes into play. Also the type of work I do chucking time is not as big a issue as the versatility as the four jaw chuck. Running parts with two centerlines as a example. Chucking parts with large undercuts on the OD is possible with the longer jaw travel. I could go on but you get the idea.
Edge Precision why don’t you turn with the B axis at 45 degrees, you can get tools designed for this and it means they can be shorter and avoid collision problems.
Although I understand CNC machining in general, some clear narration to tell us what you're doing sure would help. Nice to see your well equipped shop with well maintained equipment.
Looks like you mastered youtube just like you mastered machining. Beautiful work Peter.
Thank you for sharing your wealth of knowledge with us.

Shoot more videos, it's very interesting and informative for us. And thank you very much!
Peter- do you think it's a good idea to literally

@@EdgePrecision ok thanks for that i am just worried about this material maybe leave about .05 per side just in case ?
Yes that would be safe. You could at that point either straighten it and or mill it straight.

.01 DOC ! that kept it from moving
very nice material and I used YG drill bits too
I'm curious, when the pallet loaded from the side it seemed like there were chips on the table underneath. How does THAT work ?
the table doesnt rest on the part where the chips were laying on

how are you running this without coolant? do you remember the cutter? and the speed you were running it at?

Thanks for the explanation, i didn't realise it was central, i thought that part was offset and wondered how you finish turned an offset. Thank agian
Why did you choose a scroll chuck rather than a hydraulic chuck for your Integrex?
The chuck I use most of the time on the Mazak is a 16 -1/2” four jaw manual chuck. This type of machine if you use a large diameter chuck it causes a lot of tooling interference problems.

What software do you use to design the machining process?
The cad software I use is SpaceClaim and the cam is Esprit.
@@EdgePrecision thankful

Yes this was one of my early RUclips videos. In the newer ones I try to explain things more clearly.Thanks.
great video
Seus videos são incríveis!
А кто Вам программы на станок делает или Вы сами пишите?
Я делаю свои программы для этой машины, используя программное обеспечение Esprit cam.
cnc machining can be a lonely business..looks like you use Feature Cam..love that software :-)
He uses Esprit
Nitronic 50...this stuff must had gone offshore.
do you need people to work as Machinist?
Ah not Feature Cam..Esprit ;-)
esprit cam👍👍👍👍👍✌👍👍👍👍👍👍👍👍👍👍👍
