I depends on what you are doing. If you are cutting a pocket and dropping a slug, you don't need to break the wire. If you are cutting a punch, you can cut the wire and re-thread - or just program...

One more thing, use E3 if you are dropping a slug, E2, if you are roughing without dropping a slug.

I'm not sure if it's the same in a 4000, I'm used to a 2020.
Basically you have to make a .tec file with your strategy built in. Usually E3, E7, E17, and E10 for medium accuracy/finish. E3, E7,...

I only used a rust inhibitor once. Be sure you read the label about how much to put in per gallon. I used too much and it totally screwed up my conductivity. I had to replace all the water,...

2 hours is not unreasonable.

What over-burn are you using? Use the largest overburn (smallest undersized) electrode you can so you can maximize the power on your rough setting. I guess I should...

I can't find any information on that machine, but from what I'm used to - that burn should take about 45 minutes to an hour.

.010" wire is more standard than .012, but you have to use what your guides are designed for.

.012" is generally used for roughing/high speed operations, or when you don't need the best finish...

When I am testing a new wire machine, my top 3 considerations are accuracy, reliability of the wire threader, and maintenance. Notice, speed is not a consideration.

I've used wire machines for...

Yeah, this is the same thing that Mits is saying.

Looks like it will be a $700 fix. When this happened at my last shop (with Charmilles) this was a $20 fix that we could get at Best Buy.

Hey all,

We have a problem with one of our VX-20 sinker edms. This machine is in pretty rough shape, but the only reason we can't get it going now is pretty silly.

We load all our programs...

Hey all,

I'm new to this site so I'm not sure if this is the best place for this post.

Basically my company is at a crossroads with their CAM software. We won't be getting service for...
