Company I work for make diamond abrasive form wheels. You wouldn't believe the forms we have had to machine. Most are direct contact wheels rather than forming an aluminum oxide wheel. Many times we have had to modify a tool or insert to have clearance down in the form. We do two different processes depending on application use. One is electroplating diamond onto the wheel using nickel bond. The other is using resign/nickel & furnace to bond the diamond.

[@Jessie_Smith]

@@unaffected_covid This is a Blohm Planomat XT built in 2021. For programming you will mainly use the conversational program on the machine which is super intuitive. The part in this video was programmed completely on the machine including the dressing of the wheel. If you don't use a roll dresser and use a disk dresser instead then Blohm sells a CAM software called Grips Profile that writes the program to dress the wheel with whatever shape you want. They also sell Vector but I think they mainly use it for the CAD side. Or you can import a .DXF into grips for the shape of your wheel, apply toolpath and post the code then put it directly in the machine and use that code as a subprogram for initial dressing and then re-dressing of the wheel as needed. I will do a video on that in the future for sure but it all is super simple.

[@Jessie_Smith]

@@unaffected_covid Yes I believe that is how they wrote all the logic for the canned cycles. It is using macros in the background.

So, is the diamond infused wheel that dresses the grinding wheel a permanent feature of the machine? Or do you have various wheels with different profiles and swap them out? Also, since new cut profiles need a new grinding wheel and a new dressing wheel then who and what makes the dressing wheel profile? The whole thing seems to make sense only if you have a huge production at hand, cause I imagine that the dressing wheel is custom ordered and probably expensive as hell. Am I getting something wrong?

[@Buciasda33]

Nothing wrong. I'm sure the diamond infused wheel is custom made. I'm sure they have a large order for such parts. If it wore a single order or something like that they would have used the single point diamond to dress the grinding wheel. Everything in this video must be crazy expensive. The grinding machine itself was millions and it must pay for itself in 2-3 years.

Automatic dressing of the wheels and conveyor system from grinder to grinder. Inspection was by eye using a Matt paper tray with white light above. With that set up the mirror finish looked Matt. Any blemishes could be spotted by the operator. They were only allowed 30minutes on . Then a break, then back, and so on through the day because of the eye strain plus a limited amount of actual hours before stopping and another operator taking over.

He said he takes 8 thousands of when dressing and does that every 1/4" so that's 1 inch of grinding wheel removed for every 31.25 inches of material

[@Jessie_Smith]

It depends on what material you are grinding, how much material you have to remove and how long the part is. This is something you would need to play with the process to fine tune but the wheel will last a good while. The wheels come with different grits and other factors that could extend tool life as well. Here I am re-dressing .008" off each time but that is not exact, you may take more or less depending on what you are doing. The wheel starts out at 16" diameter and it has a 5" hole in the center so you can take a lot of material off this wheel before you need to replace it.

No you don't. You can store wheel data for each wheel you put on the machine. When you create a new wheel, you tell it what diameter it is. So each time it dresses the wheel it will automatically reduce the amount you dress from the diameter of the wheel. It will compensate the shape as well as the surface footage. Additionally, in the canned cycle for the profile it has a "radius adjustment" so if you make the first part and the outside radius was off you could tell it in the canned cycle how much to adjust and then every part after that will come out perfect.

Problem I see is the cost and time required to produce the specific Diamond dresser required for each profile. For a high value one off job, time and cost is probably worth it, but for many parts, I bet the cost justification would be not worth it. Also, how do you take into account wear on the profile dressing wheel? Damn fine machine for sure, but like everything in machining, it has its plus and minus sides.

[@Bowsarge]

So, every time you need a special shape you need to have a nee wheel designed for it. Like if you want deep, thin grooves you'd need a different wheel. Or wide shallow grooves. It doesn't seem cost efficient unless you consistently work with things that require the same designs and specifications.

[@kai.05]

To my knowledge, it's also possible to manually machine in many types of grooves for a grinding wheel by using a diamond cutter in a lather configuration. That way, you can machine multiple types of shapes without having to create a new tool every time.

@@kai.05 Not your fault, but for some reason, reading your reply really hurt my head. Probably need more sleep if I had to guess. But if I read that correctly, then for more specific shapes and designs you can manually adjust them, but at that point aren't there other machines that you could use for that project? I am just an auto mechanic, so this isn't my field of expertise. To me, this is like how one place I worked had an oil vacuum to drain cars. I found it a little redundant that I had to hook up this vacuum through the dipstick when I had to get under the vehicle to replace the oil filter right next to the drain plug. It had it's uses for vehicles with filters up top, but that wasn't terribly common. At least not in our shop.

@@Bowsarge my explanation wasn't the best haha. I'm not an expert in this field either, but in another one of their videos, a machinist used a diamond cutting tool with the grinding wheel in a lathe to resurface the wheel. I'm assuming that you could machine grooves into the wheel with a similar technique, just by moving the diamond cutting tool in the path of the desired shape. Just like with other lathes. Also, Mercedes are dumb, so of course they need a pump. Why not over engineer your cars too? I have my mechanics cert too, though I don't work in an autoshop.

@@kai.05 But that is still time you'd have to dedicate to making a new wheel instead of doing the work itself. If you only need a part cut in that way, it wouldn't be worth the time.

Then again, I don't know what type of shop this guy works for because I just got algorithmed to this video.

Is dressing the wheel worth it for just one part? How much are these wheels??

knife making super tool

Oh, my God. 25+ years ago I had to transfer the profiles on the grinding wheel with a template and pay attention to how the diamond is guided. Incredible what has developed in this area.

Technology has really come a long way in a short period of time. I can't imagine where it will go next. Blohm has thought of everything with this machine. It's amazing how simple they have made it

@@Jessie_Smith In my mind, in the future, it looks like we’re going to lose skills and knowledge. Almost as it is probably the case with regard to the pyramids or other buildings that were possible thousands of years ago. With every new technology, with every machine, we lose some skills. Let's lose some basic knowledge. I was a toolmaker at the time and years later I had also learned to be a technical draftsman. (translated from german to English, no idea if it is correct) I had to learn the basics on the drawing board and also on the PC with CAD software. But one thing is clear, I would never have been able to do what they did back then with pen and paper. Later I was able to do magic with CAD/CAM software, but without it I would be completely helpless and that makes me think. I'm more of a philosopher anyway and I like to think and the point is, with all this technology, the craftsman, the normal worker, loses more and more power and becomes a tool. You only have to think of the rocket that led to the moon landing, it can no longer be manufactured because these craftsmen no longer exist. The skills and their knowledge have been lost. However, as my master at the time said, dexterity is important, I held the file in my hand for a year. And all the other primitive options had helped, too. I could never have made the part that you made there, unless I had previously built a device that would have enabled me to rotate the part. with stationary grinding wheel. Normally it would have been die-sinked and then polished by hand. Anyway... :D I would like it if now and then something complicated just for fun had to be done with minimal possibilities. Most designers would fail with pen and paper and probably throw themselves out if they were forced to make the shit they designed themselves. That's the price of too much specialization.

@@svenboelling5251 That is true. With every advancement in technology some skill is lost but new skills are developed. There is a ton of skill lost from manual machining to CNC machining but at the same time a whole different type of skill is formed. I guess it depends on which side of it you are on. On one hand, it has made it to where the operator no longer has to have a ton of knowledge but at the same time, someone had to write the macros and language to make it that simple.

@@Jessie_Smith I'm probably one of those people who don't want to forget the basics. The core from which the rest grew. Either way, you need both. Without a seed there is no stem, no leaf, no flower and without them, no seed.

@@svenboelling5251 Very well said. I am the same way. Even though I've been in the trade 15 years and have made some super complex parts, I still watch videos on squaring a block and things like that. There is always something you can pick up on or some forgotten knowledge to relearn.

I feel like this guy should be selling me a pump action shotgun

[@Jessie_Smith]

do you need some camoflauge to go with that shotgun?

[@batmanhero2014]

To check those high tolerances you should definitely be looking at a mitutoyo cmm. They are the most accurate product on the market

[@TITANSofCNC]

That’s all we use

How is the dressing wheel formed to match the part profile?

[@Gggg22g]

Install a rotary table and design fixtures and you can broaden your part machining capabilities

[@tintruder224]

So the rotary dress tooling is job specific? On my Kellenberger, I used single point profile dressing to create various wheel shapes. I had a rotary dresser, but only for dressing diamond wheels used to make carbide parts. I'm curious as to the cost of your rotary dressing tools...is it even remotely economical for small quantity parts? (Various pitch threads, SAE, Metric, Acme, ballscrew etc in hardened shafts for example) Who makes the rotary dressing tools? Is each one custom? Or do they have a catalog?

[@kylefolmsbee3922]

On the kel-varia And kel-vita models I setup, I alternate using diamond rolls and single points. These special formed diamond rolls arrive to the shop ready to use, they are expensive to purchase and are only bought when needed depending on how complex the form is

[@DragonwoodDesigns]

Is this also called "Crush Grinding"? Like for the roots of turbine blades?

[@jacobbrea4204]

how does the machine make up for the material lost every time the wheel is re-dressed?

[@SWIM44]

What would that piece of metal you grinded be used for?

[@ypogeion]

What kind is this white-coloured cooling fluid???????

[@mehmettemel8725]

To justify the cost of a form dressing wheel like that is either you need it and put it on the job or high volume grinding as long as the customer is paying for it.As always you get what you pay for beautiful finish and accuracy.

How do you keep the metal in place electro magnet?
