Why not just knock out the middle man and make the end mills out of the material that you cut the end mills with?

that material is fragile
For you
Bruh machinists make damn near minimum wage,
My rougher is a fricking carbide upcut bit from a wood store that has a lifetime warranty that I keep bringing in every few months

Everyone laugh at the moronic name gay
tripgays were generally abused as children, which is why they come to an anonymous website and identitygay - so they can receive abuse so they feel loved. The only way you can help them stop hurting themselves is to ignore them. Let their every post go unreplied to. Eventually they try posting anon and get replies again, and they can start to heal.
your both being immature and silly. it's fine to have an ID on a board like PrepHole.
>it's fine to have an ID
No
The only one that does is your moronic ass, stop spouting your inane bullshit in every thread.

You dont cut carbide, you grind it with resin bonded CBN super-abrasive wheels.
Cubic Boron Nitride is just diamonds on steroids.
You can go get Diamond coated files, burs, bits etc etc at your hardware store.
CBN is softer than diamonds. The only reason to use it instead of diamonds is for grinding ferrous materials since iron at high temps dissolves carbon.
Resin bonded CBN wheels are slightly softer than vitrified diamond wheels.
That means they dont get glazed and need dressed as often, CBN also exhibits a self sharpening effect as it shears itself which keeps finish and tolerances high.
They also are more thermally stable at high temps allowing for heavier DOCs and feeds.
Whatever shit you think you read on reddit pertaining to cheap sharpening stones have no basis in reality with actual carbide tool manufacturing. Imagine that, sharpening chisels with chinese wheels slapped on a bench grinder is not the same things as manufacturing carbide endmills to .0001 tolerances on 7axis CNC machines.
>t, ran ANCA grinding machines with both CBN and Vitrified CBD wheels manufacturing HSS and Carbide drills and endmills for several years
I don't know if your shop is up to industry standard, but most manufacturers suggest diamonds for carbides and CBN for steel and most people I've encountered tend to stick to that.
I can understand having a preference, or something feeling good to you personally as a machinist, but don't try to say that just because you like to use something it is objectively better. You can have a preference that is not the most optimal, but don't shit on people for wanting to do things by what is considered the "right" way. ESPECIALLY if they do not have the same level of skill as a professional machinist.
I'm not a tool grinder, but our tool grind department uses diamond on carbide and CBN on HSS. We also use ANCA's though.
>Resin bonded CBN wheels are slightly softer than vitrified diamond wheels.
They're almost half the hardness. CBN wheels are absolutely not meant for heavy use on tungsten carbide.
>I don't know if your shop is up to industry standard,
We made the switch when a Norton representative came in with a box of wheels. We qualified them all and spent several days doing speed and feed testing on our custom form tool programs.
You underestimate how much glasing occurs during a fluting process, and how much the self sharpening effect of the ceramic makes a difference in cycle times.
Its all a balancing act, especially since the many different types of bonds out there all have different characteristics too.
Glazing happens when the bond isn't breaking away properly to expose fresh grit.
You can. But making a quality end-mill is precise, tedious work. For most shops, the machinist's time (aka money) spent making them + the lost productivity of not being working on client projects during that time will be in excess of the cost of the tooling from a supplier.
He's not saying make your own endmills, he's asking why we don't make endmills out of what's used to shape them.
Lmao no. There's like, 3, maybe 4 companies that actually make tungsten carbide. They make blanks similar to drill rod in the appropriate diameters and lengths, and companies like IMCO buy those and grind them into whatever they need to.
> make tungsten carbide
You need a star to make both tungsten and carbon.
They found it, not “made” it.
Tungsten carbide is a man made alloy. The ore we get tungsten from doesn't even form near carbon sources, let alone have carbon in it. If you're going to be a smartass, at least try to be correct.
i'm sorry sir I will try to do better in future
They use green carbide for the mill that they are making and then harden it.
>Why not just knock out the middle man
Knockout game is not very nice anon.
Endmills are ground not cut
