Attempting 15x Deeper Cut Than They Said Was Possible

[@Turboy65]

How much of the wheel was consumed in this cut? (Change of diameter from start to finish)

[@vintageludwig]

With a wheel that soft I can imagine it shrunk about an inch. I think the pass they showed without coolant might have consumed the bulk of that wheel.

[@johngarlick7115]

@@vintageludwigthey weren’t actually grinding on the dry pass.

[@GarthOwenGOGO]

@@vintageludwigyou can see by the nozzle position before and after there was a tremendous amount of wheel wear.

[@Jessie_Smith]

It blows my mind that you are able to do something like this on a grinding machine. Crazy how far the technology has come.

[@thebrain6389]

you can but now wise. just use an endmill to cut to depth and leave however much you want for grinding.

[@veikovasko5603]

Love thee jobs where setup/fixturing is 90% of the total engineering. Really brings out the skills of everyone involved.

[@barrysetzer]

About time you took off more than .0002" off a part, Chris! Great video

[@russellofcnc]

When the depth of cut is deeper than Barry's appreciation for Grinding.

Do you smell that? It’s not my coffee. It’s not the ground material.. Oh wait, it’s just Russell’s sweet burn! 🔥😎

@@andrewb2475 lol On a serious note, Barry is a great machinist with a wealth of knowledge to share. Yes, we poke fun of him at times, but don’t be fooled-he knows his stuff. 🙂

I love creep grinding had tooling manufactured using this method in the 80s the process was old then. But now it’s great to see how for the technology has moved 😊

[@KylieGranno]

Always taking it up a notch, awesome video everyone! Chris way to get after it man!

[@14rs2]

Cool video! Kind of wanted to see how that PLA print held up

[@antprzy]

And i thought that grinding is only about finishing. This is amazing. Nice video guys

[@Its_Ya_Boyy]

I've seen videos in the past of KZbinrs who CNC creating an "Air Knife" for their cameras to prevent coolant from hitting the lens and let them get clear shots of their processes. Don't know if you guys have heard about those but might be a cool 3D printing project and allow for more flexibility in your B-Roll.

[@Sara-TOC]

Cool video, guys! I love the innovation, teamwork, and in-depth explanation of the machinery and manufacturing processes.

[@jamessmith1190]

That is the cleanest I've ever seen a grinder

[@markdavis304]

Insane grind. Trevor, great tip on using the print orientation to help keep the part as strong as possible 👏

[@buli78]

How long did the process take? How much did the disc diameter decrease during continuous dressing? Depth is not everything. What matters is the profitability of the process.

[@ippegasus]

Парни показали что так можно делать. Рентабельности тут нет. Обычная ковка металла тут лучше подойдёт.

[@Frost.7xx]

Pretty sure it was just a test to see if it could be done. I’m sure it’s not the most profitable scenario, but I could be wrong

[@nicolespittler9530]

Excellent video! It’s incredible what you can do with these machines.

[@William_ar98]

So as the grind wheel wears down. does the machine compensate for this by lowering the Z axis and the diamond dresser the same amount? Awesome!

[@bogiesnogood]

Guys that is freaking awesome I ran a kellenberger kel varia twin head for many years never did we make a cut like that I believe our max was .010 plus do a finish dress before grinding to size this was truly awesome so cool I love the continues dress that's handy you guys are rock stars boom

Those are CHIPS?? haha Great video Chris, Trevor and Nate!

[@StauterAdventureCo.]

If you listen closely, you can hear the pucker. Lol AWESOME job, Chris!

[@Joe___R]

I'm surprised you didn't just print the nozzle in stainless steel but it wouldn't have made for a good advertisement for markforged 3D printers.

[@Fine_i_set_the_handle]

You're worried about the strength of the 3d print but you don't even print it solid

[@bradley9856]

they did though

[@cvantrease1231]

Infill has little impact on overall strength of prints it’s more just a frame for the walls and top surface to build off of

[@donniehinske]

That’s DEEP 😂 good video everyone!!!

[@chrisbarnes2823]

We used to Creep Feed grind turbine blades at Rolls-Royce in England in the late 70’s.

[@byfordbarnard2264]

That’s insane!

[@nickthelebo]

These grinding guys are a diffrent breed

[@bill4639]

Loving the grinding videos guys

[@TheRealAirdoo]

Based on the tool paths shown, I feel like the inlaid carbon fiber didn't actually contribute that much, as the un-reinforced layers could still separate as they would in the PLA printed one. I have a feeling the print orientation was the real difference between the nozzle here and the failed one. I would be interested in seeing the same nozzle printed with just the polymer and see if it would hold up. I've worked in the additive field with too many engineers and operators that overlook the inherent advantages and disadvantages of the process they are trying to utilize and make decisions based on those factors. Print orientation being the biggest factor when I'm called in to diagnose why a part is failing in an application when the material properties exceed that of the needs of the application. Just because the part imported into the slicer one way doesn't mean that's the best orientation to print it.

[@cammccauley]

Currently running a manual 14x72” chuck Mattison surface grinder. NEVER IN MY DREAMS lol

[@failurehaus5979]

SLA works well for these nozzles too acrually, had coolant at about 50bar through one and held up just fine for a week of continuous production

[@andrewwilson8317]

I have used a manual surface grinder with a creep feed facility. It was never a pleasant operation to carry out. Much preferred multiple passes of a few thou each time!

[@sebbes333]

Cool that you CAN do it. *But in what realistic scenario would this be used?* instead of just having a mill remove like 99% of the material & THEN make the final polish on it with a wheel like that?

[@christophervillalpando5865]

Doing something like a hair clipper blades or saw teeth you cant rough that out. Creep Feed is the way to go

[@phily-ue6et]

Here's one for you to try. Bolt a 8 inch cup grinding wheel to a milling arbor, put it in a vertical milling machine and mill through a chunk of steel as if you were face milling with no coolant at milling speeds and feeds.

[@Sjaak_PD1SRM]

great job, the right tools is the secret to succes

[@EntropicTroponin]

[@aleciacarpenter7856]

How much of the grinding wheel did you lose for that cut? Cost wise, would it be worth it or is this just for demo purposes?

[@ssl3546]

obviously this is just a demo showing the possibilities of buying top-end machines, and whether it's worth it depends on what you're charging the client...

[@kevinkc3onohelijeepworld953]

Bad@ss Grinding 😊

[@Proxima-J-]

Not sure why this showed up in my algorithm but I’m glad it did

[@toplesstattoo4301]

How do you compensate for the wheel shrinking?

[@sportswolf1]

That's impressive!

[@fg786]

The sides of the wheel are cutting aswell but are neither dressed, nor cooled or cleaned? If the wheel is so soft that it breaks under your fingers, wouldm't the cleaning nozzle destroy the dressed profile? Wouldn't it be advantageous to have that nozzle do it's work before the dresser?

[@nikolawandler9399]

1 question, what's the point or application of this?

[@KP21530]

Can you guys please make a video on how to chamfer a very small hole on rubber with VMC?

[@The_Original_Drex]

[@TricksterJ97]

I guess they were wrong. Who are they? Tyrolit? United Grinding?

[@465maltbie]

Do you know how much of the wheel was consumed in that one cut?

[@anon-means-anon]

Not sure how I wound up on an undisclosed ad for markforge or why someone would hog out all that material with a grinder

[@RippenSXS]

That's crazy!

[@mattlarson9897]

An inch and half depth of cut is not that much, until you see how wide the wheel is! It is all about that surface area contact. I would love to see how much power the motor was drawing when it was cutting that!

[@fast-yi9js]

so like, thats cool; but why wouldnt you use a cnc machine for a cut like this?

[@christophervillalpando5865]

This is a CNC Machine

[@fast-yi9js]

@@christophervillalpando5865 I mean with a "traditional" endmill toolhead. whats the advantage about this to justify burning an entire abrasive wheel?

Yes Creep feed grinding has many uses

[@willmc11]

Can’t they do through spindle coolant for grinders?

[@cHAOs9]

Hmmmmm... how could we possibly make our coolant nozel the same shape as the wheel? You're referring to the wheel that's only job is to grind everything it touches to the exact same shape as itself? Yes. Why do you ask?

[@BuildBreakBuilds]

Why would you want/use such a soft wheel. Any advantages?

[@catranger01]

They didn't say what the material, hardness, tolerance, and finish requirements were. Most machinist would mill, heat treat, then grind IF required.

[@mikethespike7579]

I can't help pitying these poor guys desperately struggling to produce excellent results using such primitive machines. My thoughts are with them...
