Does anyone die-sink?

[Toolfab]

I have run into a problem. I have a job that I need done, and I dont have the machine to do it. I am pretty sure the only way to get this done is by die-sinking. I have put the part toolfab-1 in the MC9 folder on Jay's FTP.

 

If there is anyone intrested in talking about this please feel free to either post or email me at [email protected]

 

I would appreciate any imput that anyone would have on this tool. I have never done anything like this and it has been very fun to think about, until I relized I cant do it..here.

 

Thanks,

[Harryman]

Hey Paul, cool part.

 

You might want to see if R Stuart can help you out. This is doable on an Integrex with B and Y axes.

 

I'm already working 60 hrs/week.

 

Just curious, how long do you think this should take to Pgram? I'm ashamed to say how long I think it would take me.

LMAO...it took me almost a whole day to figure out that I couldn't do it.....

 

[Toolfab]

BUMP cuz I am desperate....lol

[Eazy]

All the way from Australia. Toolfab, you certainly have a challenge ahead. If the boss gave me that model I would be looking to get it done elsewhere. Good Luck.

[mayday]

Toolfab, can ya send it to me to look at. I still fail to get to the ftp site. I may have some leads for ya

[Harryman]

Hey Paul, Jack gave us another story and, well... Someone may have poked a little fun your way...

Paul, thats an abortion are the non indexable teeth inefective??? can you add clearance to get to the seats??? its doable on a stinker. but your talkin lots a setup/fixturing

nothin against ya but there are a lot of indexable shell cutters out there. what is the special purp for this thing. curios thats all

[Toolfab]

I know its a mess, but these tools are for a weird arse application. They used to be manufactured with a helical carbide blade!! We used to heat the carbide up and TWIST IT along the helix.....have you ever twisted carbide....ever heard a cat skinned, thats what it sounds like!

 

We pretty much need it just like that. The inserts get face ground in the tool! Thos inserts are cast than mounted then ground!

 

Harry, thanks for the heads up! That is some funny stuff!

You mean those other teeth are FUNCTIONAL? Is it a High Speed Steel body? Sorry for shooting my mouth off about it being doable on an Integrex.

 

I'll shut up now.

[Toolfab]

Yes they are functional, and yes it is a highspeed body. The OD and the face of the carbide inserts all get ground once we mount them to the body, that is if we get a body to mount them too....

 

I feel like Ron right now..

[John Summers]

Carbide CAN be twisted. I've seen it done. You need special heating equipment. It looks like it would be the best approach for this job. The pockets look mean. Couldn't you burn (EDM) them in? You're not having trouble with the helixes, are you?

[Toolfab]

No John, rolling the helix in is not an issue, and we HAD the fixturing to twist carbide. We actually used to do it. We would like to get away with it, twisting carbide is really not that acurate. Thats why we are triing to change these tools to indexable.

 

I still havent found anyone that can EDM or Die-sink these tools for me. I think we might have bittin off more than we can chew here..lol

[John Summers]

The twist in the carbide could be more accurate if you used dies to finish the bend.

[Toolfab]

We have dies, but the flex, expand, retract, cooling and everything else just isnt that easy.

[maestro]

Just a thought here. You might call Iscar. They have a custom tooling shop here in the DFW area where they make custom toolholders and inserts. They have a 9 axis grinder there. It sits on a 6 foot thick piece of granite. I don't know for sure if they can do this or not. Might be worth a call though.

[Toolfab]

Thanks for the tip. At this point I will try anything.....lol

[Lars Christensen]

I might be way out of my league, but to me the pocketes do not look that tough to CNC EDM, I would make a electrode with one pocket and having the part indexing around.

Are we talking onely one part?

What is the tolerances?

 

I once had a crazy part that I could not machine, it ended up that we contacted Uddenholm and they molded the part for us right from the factory, that could might be a way to get the helix shape, and then WEDM the center, and EDM the pockets.

[Lars Christensen]

Never heard of twisting carbide, how accurate can you do that?

toolfab,

i looked at your part and like mayday said i can not understand why you would need such a part as compared to what you could buy from any of numeras companies.dont get me wrong just curious.is this some proprietary thing or something along those lines?

i believe it could be edm'd with some time and thought, but why.

i believe with a inserted tool like that you would not be doing any finish work,so why the need for specialty tool?

just wondering.

good luck on your quest hopefully youll come out ahead.

Yes, its on of those jobs that you cant talk about, you cant change, you cant deviate, you just have to figure it out..

 

 

So Lars, you think you would be able to EDM this? I already have the helix milled in.....I need the pockets burned in.....If you are up for somemore details give me an email..

 

[email protected]

Thanks for the continued responses. I appreciate it. I still need help, anyone interested?

[jbel]

I said this about machining tungsten and i will say it about this

 

YUCK!!!

[Toolfab]

Thanks jbel, I needed that.....

 

j/k

 

[Lucky]

Hey Toolfab,

 

I looked over your file. We can EDM this job for you. No problem. Are you only interested in the insert pockets or do you need the entire flute machined out? I am e-mailing you directly. Let me know what you need.

 

GO TONY #20

[Lars Christensen]

Hi Toolfab,

 

Put Lucky 1st on your list.

 

The shop I work in, do not have a sinker good enough for this job. However I can go over to a body of mine, and use his if needed. It is not a problem doing the pockets in the EDM. Did you do the helix on a 5 axis mill?

 

If things do not work out, let me know.

 

I am still corius about the twisting carbide.

 

Lars
