All I can say is WOW! This is some really creative solutions to some severe machining challenges. There are probably few shops out there that have the capabilities of custom grinding in house, and on the fly, custom cutters and gun drills like you are doing here. The cost of this part with the wear you get on the cutting tools would just eat any profit up very quickly for your average shop. Your capabilities bring a lot of value to the table on a part like this. Hats off to you sir!

I made me and my wife’s wedding rings from inconel(about a half size big so they couldn’t get stuck on your finger lol) but with only about a 0.06” wall thickness I chucked up on them after parting them off to finish the other face and break the edges and the ovality stayed really concentric even with that thin of a wall. VERY strong material. Even eats up inserts designed for inconel like it’s nobodies business!

Thanks as always. Hey when spotting do you believe you should spot with an angle so the drill hits the spot hole with the point first? (and not hitting the cone from the spot with the drills edges) So with 118 degree twist drill use a 120 degree spot drill minimum? Thats what Ive read but also heard otherwise. Thanks again.

The customer supplied this material so I can’t give you a exact answer. But this type of inconel costs around $20.00 a pound. So if the stock was (I can’t remember the exact dimensions) say four inches in diameter by twenty inches long. That would be roughly $1,500.00.

Thanks I will check into that. I am using a Sandvik finish grooving insert grade 1105 witch is the grade that Sandvik recommended. Its working fine but its just a finishing tool. I resist the use of Sandvik inserts unless absolutely necessary because they cost so much. To give you an example that Sandvik insert I'm using costs $21.50 each (The only reason I'm using it is because their tool only holds that insert) the insert I'm roughing all the grooves is a ToolFlow top noch insert (Interchangeable with other brands) it costs $14.30 each and its roughing or doing more work. I have many Sandvik tool holders and silent boring tools they are indispensable and I wouldn't want to do without them. I just wish the could be more competitive with the price of their inserts.

The finish turning inserts last enough to get to size but no more. I can’t run two parts with one tip. The rough boring bar you saw in this video will rough the entire bore on one tip but no more. On the OD roughing (next video) I have to index the insert every pass.

Hey Peter, when indicating at 8:50, how do you compensate for the effects of gravity on the indicator as you spin it around? I noticed you weren't using a coaxial indicator which is usually more resilient to shifting the orientation relative to gravity.
@EdgePrecision6 жыл бұрын
I have tested this indicator arm and indicator for errors due to gravity and it has very little. In other words not enough to worry about. But you are correct some arms have quite a bit of error. Any one that uses indicators in the horizontal position should test their holding method and the indicator it self for error due to gravity. Actually the spindle probe would be the most accurate because it’s calibrated in both vertical and horizontal position.
@RambozoClown6 жыл бұрын
Aside from travel limits, is there any other reason to index the boring bar to 12:00? I would think it could just as easily cut the bore at 3, 6, 9, or with two axis motion at any position. Just curious if there is something that makes that position the most ideal.
@EdgePrecision6 жыл бұрын
The way the machine uses its offsets for turning you have to do turning in the X axis. It would be possible to do what you suggest but as I said you couldn’t use the normal wear offsets or tip comp for the turning tools. Also this machine only has 10mm X minus travel. So everything milling and turning has to be done in the X positive direction.

The Oleophobic coating on this window to repel the water/oil was old. In the next video (I haven't posted it yet)I replaced the glass window. It now does better. There is a limited life to the coating under the coolant. These windows are expensive and I'm trying to stretch out there use as much as possible. The thing about trying to use anything mechanical is the power required in the wet environment and the noise it would make. I want the sound as much as possible. If I was to use air to drive things it would require a lot of pressure and volume. This again would make a lot of noise. The air knife on the camera case only requires about 20 psi to function and is virtually silent.

I use a .0001 dial bore gauge to measure the bore because, two reasons. 1: A dial bore gauge set to a stack of properly ringed together gage blocks standard has more accuracy and resolution than a 3 point mic. 2: if the bore isn’t round or has a taper you can see that on the dial. A 3 point mic won’t show that. Or at least not as accurately.

Tremendous video, you teach in a way that's easy to learn, thanks for continuing to take the time to make them. I would like to ask you about how you checked your part for concentricity by rotating the dial gauge and the part together. I can see why you need to do this as clocking the part true in the 4 jaw doesn't mean it's parallel to the centre line of the spindle just true to the 'centre' of the steady, but for this method to work don't you have to assume that your tail stock is 'spot on' centre (and you have show use before that yours is adjustable) or else aren't you just measuring any error between the tail stock and centre line of the steady?
@EdgePrecision6 жыл бұрын
Rotating the part the way I showed isn't for checking concentricity. It for setting the X and Y Zero on the fixture offset. If there is run out at the end of the parts OD and your indicating that OD. So if you rotate the part with the indicator and remain in the same location on that OD. You will in this way will be eliminating the actual run out of the part and be finding the true center of rotation.
@MachinedComponents6 жыл бұрын

@EdgePrecision6 жыл бұрын
It depends on the type of inconel and its heat treat. Inconel is a age hardening material so it can be heat treated to increase its mechanical properties. It doesn't get real hard like say steel but it gets tougher. This particular kind 718 can be around 120 ksi yield strength all the way to about 160 ksi yield. When you get up in the 150 ksi yield it is considerably harder to machine than say 135 ksi. There is what they call a double heat treating process that improves it's machinability. The rating goes something like this. Low carbon Resulferized steels have a 100% rating. The 700 series inconels fall into an area of 9-12% rating. That may give you some idea.

Peter, thanks for sharing, always enjoy watching you videos! I have a question though, after you chucked up the part in the 4 jaw and indicated the part in by the 4 jaw, How did you know that the center in the end of the part that the tailstock went into was running true? Was it center drilled in that setup and not shown? My thought is that if that center drill hole runs out a little the tailstock could influence the part to run on center during the turning operation but after you release the tailstock the part goes back off center, and you end up with a warped part. May be I'm just over thinking this... thanks for sharing

I didn't show it in the video but I had previously prepared all the blanks with the centers that ran true to the other end.

Jeez...That's a lot of carbide! Do you regring your drills afte? Were I live the machine shops mostly use manual machines for servicing agricultural equipment, and usually if an edge get's dull they touch them up on a diamond wheel to avoid using another edge (no matter if they are coated, uncoated or whatever) but for turning to a close tolerance on such tough materials this would be a nightmare! Maybe you could stack a few used ones and get a lead chipbreaker ground into them.

"I need 1-2 thousanths tolerance on an inconel C-276 part." Umm.....That's typically a wrought alloy for welded assemblies. Use a material that's machining friendly please?

Inconel is a fucking nightmare if you run production.

You watch this and its like, yeah I do that with a special reamer that I ground. You know like, I am making this sandwich with these Tomatoes that I genetically engineered... like custom grinding a reamer is what you do while chatting on the phone. No biggy.
