Wire edm slugs

[JMahon]

Having issues with slugs shorting out the wire... 5" long part.

 

Anyone have any tricks for dealing with this?

 

I thought of trying a no core path but the boss is worried about cycle times.

 

Opinions?

Some details are needed.  I assume you mean 5" tall (thick) and what size is slug?  Are you doing anything now to control it?

[JMahon]

Think of a triangle with a .375" inscribed circle, with .060" walls.

I'm not sure what they're doing now I know they just mentioned they had trouble last time they wired them. I'm just helping out now that it's in production. I suggested no core but everyone's saying it'll take too long... Gonna give it a shot tomorrow anyways.

[JMahon]

And yes, 5" tall

you don't say material but a magnet on top before the cut is finished might work

I agree. We use rare earth magnets

One order of stainless, one order if 6061

Is the hole a start hole or are you wiring the outside of the triangle.

Can't find them in by bestiary.  What's their armor class?

Start hole

Start hole

Thats your biggest problem. I would use a smaller start hole so that your flush cups can seal off during the cut. If you cant then use flush cups with a smaller opening that will seal off. I imagine that your slug is moving with such a thin wall causing issues. If you cant do any of those things then program the part to rough 1/3 of it at a time to drop a slug and then skim after all have dropped.

I believe you're looking for the "Dungeons and Dragons and Pathfinders, Oh My!" thread.

Cool I'm gonna give it a shot later.

So no go on the no core path?

It would be a long long burn if you did.

Short of draining the tank and super gluing the slug not much I think can be done in those materials. I have done just that where I would stop 75% through the part. Drain the tank and blow dry. I would then put a couple dabs of super glue on the slug use accelerator to dry then finish the cut. Normally the slug would stay in place.
