How material type affect resin life

[RJT]

We cut a 4 inch thick aluminum block (about a 3 hour rough cut, no skims) on our 2 year old Fanuc wire EDM, then some thinner aluminum parts and it killed our resin bottle. I'll try to attach a picture of the screen that shows resistivity. I don't remember it ever having this much effect on the resin, I , I remember it can cut up the filters if they are not coated, but never the resin. Is this usual?

Aluminum can be rough on the resin, It might have been a defective bottle too.

Al is always rough on the resin. I try to avoid it, but you cannot always do so. So we charge accordingly and amortize the extra costs. Part of the business.

Al also will clog your filters pretty fast. As he ^ said, just add into cost of job knowing you will use filters and resin bottles faster.
