How to recycle solid carbide with Sandvik Coromant 

You can sneeze at it it's ok.

Wow I can’t imagine what you spend on carbide tooling then if you are getting back 60k in recycling value!

@@georgeowen2083 If they used uncoated plates and resharpened them after blunting, they would save even more.

@@Freekniggers thank you

Bravo! Recycling makes sense to companies when the see $$$ coming back to them.

Yes, and if really though about how far, small private manufactures might go for savings, with the right modifications of the machi e tool, like 3 d additive laser 're building of cutting edges, and coating, and sharpening grinding, all at a workstation 😎

As a hobbyist, even blunt inserts are valuable already. You can easily sharpen them on a diamond wheel and use them again and again.

The metal value is still there. The reason old milling machines will always be quite expensive is also because they have such a high metal scrap value. Sucks for a hobbyist trying to buy an old machine because even something from the 60s still costs a few thousand. Compared to a car which is mostly very thin sheet and needs a lot of refining to recycle you can buy for a few hundred and still drive for a few years.

@@excitedbox5705 On a plus side that metal value will not go anywhere and will still be there when the machine becomes scrap even for you. It's a deposit, not a cost.

@@aleksandersuur9475 I know but it is a big investment to make for a hobbyist. Almost better to buy a modern lighter weight machine for the same price and get the modern features and capabilities such as high speed spindles. An old bridgeport costs me more than importing a mill from China of the same size. An old milling machine from 2000 costs as much as an entry VMC or CNC lathe.

Off topic but relevant Look at how many telephone poles there a tree e on your next drive. Two people per ple installed them, I know cause I'm a sparky that has.. Its mind blowing to see such high numbers. Count them. Itsbits, just like carbide ,

Imagine now all that cobalt, pricy as gold for EV materials and chemistry in general

Stefs Engineering I use their products at my job. They are very good with their customers, they’ve sent reps to our plant to answer any major issues we had to deal with. And no I don’t work “for” them. Just wanna clear that up. Lol

Metal is metal. You can always recycle it. They are just refining it into the starting materials.

Haha yup

Lol

fishingfool211 try to break tungsten carbide tool bit with your hands or teeth.

@@shenghan9385 makes for delicious candy

mackk123 lol. It maybe delicious. You just have to be careful chewing it. Don't break your teeth.

M Hamma from what I’ve heard they use a grinder with tungsten carbide inserts. Presumably they would be ball shaped like the ones seen on mining and boring equipment. It would make sense as they can make their own tooling, too.

There made be trade secrets in that process. By developing their own method, they might be able to do something more profitable than methods used by other companies.

@@bunnythekid I don't think a grinder would work? I would rather go for a crusher, an impact crusher or a roller crusher.

Dominiek Demaerel Tungsten Carbide would be really hard to crush. It has great compressive strength. One way to recycle TC, which i only recently learned about, is reacting it with zinc in a furnace. The tungsten carbide swells and becomes porous. It can then be milled back into a powder.

@@bunnythekid Tungsten Carbide is realy hard, that makes it realy easy to crush. Take a normal hammer and smash a tungsten carbide insert, it will shatter into tiny pieces.

But pure Wolfram is also very nice, even without the carbide compound.

Thank you for your comment! Glad you enjoy our videos! Here you can learn a bit about vibration damping: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VCxm3vTWgvU.html

1AB09CC3 insight is the correct word. Doesn’t really show much how tho.

It was her older sister Zackourney Weaver :D

Could have been an initial lift off a stack with limited access, given the height it started at. Perhaps he should have backed up, lowered the load, taken another stab at it to bring the load closer to the back plate but...

Carbide shrapnel grenades sounds sexy AF.

How much is the scrap price?

@@TheSoundOfTwang It's like the stock market prices change daily ... you have to look it up locally

Lmao what

That is a sad attitude, as sending back the tools for recycling is not just about the company - it is about saving the Earth´s resources which we all know are not infinite.

I want to sale tungsten carbide scrap .

I thought the same thing, cheers from John, Australia.

userwl2850 This has nothing to do with the manufacture of the inserts, its how the individual chemicals are recovered. All the individual chemicals (tungsten cobalt etc) are separated and then recombine in different ratios to produce the inserts.

They are all of different grades. Sandvik offers more than 220 finished products grades.

Kevin L I'm assuming you go to the scrap yard already. Just bring your carbide with.

Hi, Sandvik Coromant is committed to provide different types of packaging for our buy-back program and a small container for the collection of used carbide is available from our website. The small container can be used internally and can be placed at the end of the production line or on a desk. For efficiency purposes, we ask customers to transport the buy-back materials using our 20KG packaging. Currently, there is no smaller packaging. For customers who want to return smaller volumes they may be able to do this via their local distributors. Best regards Jason Purcell Global Services Manager

Bring them to a local machine shop that DOES recycle, or a tool supplier that will collect them for recycling.

Hi! If you are talking about solid round tools you can regrind them up to 3 times using our Reconditioning service. You find more info on the topic here; www.sandvik.coromant.com/reconditioning

P0tat07 Infinite. Material properties don't change. You do lose a bit of the tungsten each time, so after hundreds of processing cycles eventually no tungsten will be left.

Hi, Carbide can be recycled as long as it contains tungsten. Since we use a chemical process, it doesn´t matter how many time it is recycled. It is mixed with other material and can as new tungsten carbide be used for all applications as well as cutting tools.

P0tat07 they can be recycled forever. Because they are broken down to the constituent materials like tungsten and cobalt. And so called carbide is just carbon.

@@sandvikcoromant hello sir

No. We have worked with recycled material in our production for years, and you can trust that the inserts have the same performance as if we would use virgin material only.

May be proprietary processes.

Darren G Last time I took some in it was $3/lb. I just looked and it's above $6/lb! 😵

And this stuff is dense.

Hi Darren, The current rates are: Europe - € 16/kg (€ 7.2/ lbs) Americas and Asia - $ 18.8/kg ($ 8.4/lbs) Best regards Jason Purcell Global Services Manager

what is Your price today? How much in USA and Asia?@@sandvikcoromant

Just contact a local or regional Sandvik sales rep. They can set up up with the collection boxes and buckets. Typically, Sandvik will pay a better price compared with other scrap vendors since they are the end user of the returned material. Go to their website and find a sales guy in your area.

Dan Sammons Thank you Ill try to contact them.

endmills are grindable but after some regrinding they start developing small cracks because of material fatigue. With inserts it could mess up their properties since they would become thinner. Another problem is the coating. If you're interested you can look up the Swiss manufacturer Fraisa. They offer you a Toolcare service where you buy their mills and after using them you can send them back. At their factory they get decoated, grinded down a little and then recoated.

@@jannpatrick6392 Thanks. :)

grinding takes away material so the insert is no longer the same size in cnc every insert has to be exactly the same or there will be size differences in the workpiece

@@janvanruth3485 yeah, but you could compensate for that with tool correction. But it's way better to just have all the same size. I guess that grinded inserts would be twice or more the price of sintered inserts.

@steve gale in my company we experienced this mr. genius... And yes, i'm no engineer yet.
