Amada FOL-AJ-3015 piercing problem 3/8" HRS

Amada FOL-AJ-3015 piercing problem 3/8" HRS

(OP)
Hey all, just joined and this is my first post. Please be gentle.....

I have the Amada 3015, 4kw and it is blowing the pierce on about every 6th part or so.
Did the normal nozzle center, lens clean, check H2O and shot oil.
I am using water cut because I have found it to cut great in 3/8" and 1/2" and I've been using it for a couple years.
I found this site and am amazed with the knowledge here.
So rather than fight it, I figured I'd ask around.
I watched it and it just blows up when it starts the pierce.
I included pics of the cuts and conditions.


Thanks in advance,

Matt

Matt, do you also loose cut quality after pierce? looks like cut got bad and you skipped part?

LaserSpyder,

No, the cut quality is great, except for that one where I stopped it.
I stopped the cut when I saw the pierce go bad and it had a fat blob of slag where the cut was going.
I finished up the 200 pieces and had about 25 blow-out pierces.
Fortunately all the parts came out ok, since I have a pretty long lead-in.
Here is a pic of the cut quality even after an ugly pierce.

On the bad pierces, it looks like there is a burst of power way hotter than a regular pierce.
Kind of a little explosion with slag going everywhere.
Not the usual controlled pierce.

I would try too reduce initial duty.

RE: Amada FOL-AJ-3015 piercing problem 3/8" HRS

are you sure the pierces in the cut program are programmed all the same? if its every 6th part exactly I would look into that machinegun

Ok, I'll try to cut down the initial duty.
I guess since I have an extra long pierce cycle, starting a little less won't hurt.

It's not exactly every 6th part. Sometimes it blows out 2 in row, another time it went 28 parts between blow outs.
Since it is one part called up with a macro, I wouldn't know how to change the pierce conditions from one part to the next.
It only cuts the outside shape, with no other detail, so there is only one cutting condition.

Thanks all,

Matt

If the material is not pierced all the way and it starts to cut, this could happen for thick material. Your gas pressure for pierce is too big. Reduce it to 0.08 and thry.
Sorry for late responce.

Valdanos,

Thanks, I'll give that a try next time I cut 3/8" HRS.

The material I really have a hard time cutting is 3/8" and 1/2" Stainless.
I just haven't been able to get it to cut consistent.
Well, that's not true. I cut it consistently bad.
I'll be asking some questions once I get to that.


Matt

RE: Amada FOL-AJ-3015 piercing problem 3/8" HRS

Dont know if this one was solved or not.

But as what i can see from the picture, you are getting the blow because its not meeting the pierce time to get thru the material?

If that is the case try what valdnos suggested, reduce the gas pressure, 0.08 or 0.06, also try increasing your intial piercing duty.
You can also play around with the Freq settings on pierce.

This is the suggestions i can give based on the pictures and intel you have given.


And really sorry for late reply, havent been active here for awhile.


Let me know how it goes.
