Okay, so to review: -Raw materials are received as tungsten carbide powder and a binder (typically cobalt or nickel) -Raw materials are blended into a slurry and then dried -The powder is compressed into a compacted powder material -The material is machined to the desired product shape -The product is sintered at 2500F in an argon pressurized environment

Greetings from a former AGS employee. Ground a lot of your stuff. Can't say I miss grinding carbide all that much but it was definitely a learning experience.

My dad worked for many years in a tungsten carbide plant in Madison Alabama. Worked hard to maintain machinery and keep the plant going. Alot of the machinery in the plant is one off or cobbled from other industries such as flour Mills. A large piece of machinery tipped Over onto him and broke many bones in the lower part of his body and it changed his life forever. BooBoo gave everything to that place.

I pass this place in Lowber all the time and always wondered what exactly is going on in there. Cool video.

Great video! thanks for sharing!

Mr Mike This is a genius innovation ,i am proud of you and all the industries producing the carbide ,including the producer of this video thanks, my knowledge in science and technology till date ,i own to my curious attitude and your detailed infos

great job explaining it

Very clean )

Tungsten carbide is essential for a high tech economy. High performance machinery cannot be made without this material......

Nice video. What about carbide tools with cooling channels, especially twisted cooling channels in drills? What about coating steal with carbide? How shrinking works in this situation?

Good job on the documentary

i hope they have some kind of really good air filtration mask on... you dont want to breath in cobalt powder

Are cobalt and nickel used to make graphite?

I have a questions theres carbide teeth file and im curious how do they form those intricate tooth

We used to make tungsten carbide stamping tools that would take a million hits + before needing sharpening. Best way to machine this stuff was EDM but in the early days all grinding was done by hand = sometimes to a a tolerance of .0001" - that's 1/10,000 of an inch.

I design and program for a carbide manufacturing facility. Every material batch has it's own shrink ratio depending on the percentages of cobalt and nickel, etc. It truly is an artform in machining soft carbide as it chips and also has ability to cause fire. With materials higher in cobalt percentages, it tends to be more "waxy" and tends to build up. You machine soft carbide dry while using airlines. Though it is a chalk-like material in the "green state", it is very abrasive and requires diamond coated tooling. When we are finished with a job with a particular material, we clean out the machines so we can reclaim the material and press it into more billeted blocks. The carbide industry is very much different than your traditional steel manufacturer.

@@LegendLength there are multiple states of carbide. It starts off as a slurry solution like substance before pressed into blocks with a wax-like binder. It is then placed into a furnace and baked at very high temperatures. At this stage, the "green" carbide is now machinable as it is a chalk like material at this point. We use a band saw or sometimes a mill to cut stock material to size before machining it. Carbide chips extremely easily, so your approach and departure of tooling on a said part needs to be done in such a way it doesn't blow out or chip. It is extremely abrasive and needs to be cut with diamond tooling while using a vaccum system and live air lines. Being that it is very abrasive, it is also subject to creating fires. If you have a carbide fire, the only way to put it out is to smother it of oxygen. The material itself is very dry and should be handled with gloves. It has the ability to absorb and suck the moisture right out of your hands leaving the skin cracked and dry. All of the material has it's own shrink ratio based in the percentages of cobalts, nickel, and of course, tungsten. If I want to preform a 1" diameter hole in a part, I will have to actually machine it at say 1.200" diameter for it to shrink to size in the furnace. We are accurate down to about .002" - .003" per inch. Like I've said - The manufacturing of carbide is very unlike that of the world of other metal working industries. Truly an artform!

pretty neat video here. Sad so many people who have no idea what this material does or how it impacts there life have to leave cruel ignorant comments. if they only knew how much carbide is ingested with every bite of a chocolate bar they would realize how much greater risk they are for cancer than the people in this video.

The tungsten carbide powder that is pressed under high pressures is strong enough to undergo basic milling and lathing in its green state. Therefore, parts are machined *before* the sintering process(in this case). Other relatively 'soft' metals usually undergo machining after sintering. But in the end everything depends on what kind of possible characteristics you desire the product to have, which can be vast, especially in powder metallurgy.

@deansmith9496

isometric presses. carbide can be machined in its green state with no problem if handled correctly and machined at correct speeds. first off, the press compacts it into a "solid", from there it can be "shaped". from the looks of it, you have no clue how to machine or even how hard metals produced. go back to your button pushing operator job and let the adults think. i dont see whats so hard to understand?
