stamina processing

[marman]

hello to all...... I need help from you.
I have to work with the stax in milling (family of steels) and I would like some testimonies, from who has already dealt with this material, to get info and start my work.
processing concerning sanding, grinding and finishing...... !
Thank you.

What do you need?

the stax is a great steel from molds, often used for molds from plastics type pa6 loaded glass or similar.

has excellent wear resistance created by fibers or gases.

hi technomodel thanks for your answer mah you had to deal directly with this steel? i.e. did you work it personally? my doubts are mostly in sanding since the tool supplier gives me parameters that personally do not square much to me.... i.e. it gives me a speed of cutting vt of 160m/min in a tool d=50 to 5 approbing plates about 0.8m/min.
So at calculations made it turned out to me s1000 with f4000.0 with prof.pass 0.5... which, after a test made, I see that the finish is vibrated improves if I lift the turns to 1500 and I carry the feed to 2500 but is not an excellent finish as I would.a sto' point I ask...... I guess something? or the parameters that gave me are not accurate for this kind of material?
If you've already dealt with operationally, how did you work it?
Thank you very kind.
Hi.

I worked it years ago so I don't remember the parameters well.

However, they were not disconnected from the parameters used for other commonly used steels.

so to the eye it seems very high advancement for tooth, sure of calculations?

If you have the insert catalog you should easily find the parameters to use for calculation.

then you must also evaluate the type of insert, that does a lot.

 

[marman]

bhe the calculation of the parameters makes them directly cad-cam so I can say that we can be sure then we can discuss everything else. Frankly, even to me it seems high it is advanced for tooth that then consequently raises very speed of advancement (feed).
the inserts are plaques of the kjocera, like the frieze, precisely how I told you of impact in the piece to about 45°.tu that advancement for tooth would you give? In your opinion?

 

[TECNOMODEL]

In fact the calculations come back for that data.

It seems strange to me the speed/feed ratio.

Already for years it has been understood that to reduce the times you must have high number of turns, high progress and low increase of pass.

by memory therefore with benefit of doubt: brake ø30, 3 circular inserts, speed 10000, feed 3000, increment z 0.1

can you post the inserts page so you know what we're talking about?

 

[marman]

In fact, it is well known that high advances and low depths of past........ and however if I lift the turns and slightly lower the progress also improves the finish!

Mom that bad site.
If I don't know Norwegian, does there not exist a search to find that fried in an understandable language?

However, that in the image has 6 inserts, not 5.

and still need the insert data, what do you use?

 

[marman]

I searched everywhere but they don't provide much......as data!the fresa in figure you have 6 sharp but it's a standard photo that put on all those pages...... in Italian I didn't find anything unfortunately!
However milling mfh050r-10-5t-m/thn07671 and inserts are tma05606-ca6535 (somt100420er-fl)!
These are the cut codes and inserts!

 

[TECNOMODEL]

how they do not provide much, and how should one do to work?

ask who sells them to you that you send a catalog with the cutting parameters.
if it does not change supplier, and quickly too.... .

As soon as I have some time I try to do a research

 

[marman]

I know...... I take back what I've heard of you......... but unfortunately my employers for the moment want to work with him (it's a representative) and so I just have to do their will...!
And I don't see it clearly in the situation. I asked someone here...... but I will try again to ask....
Anyway thank you for your interest.......

 

[TECNOMODEL]

the only thing I found does not refer to those inserts, however from a fz 0.1-0.2-0.35 and a vc of 80-140-180

even if they are not the same inserts according to me are more correct than those you have.

for the representative speech ok that they want to work with him, but you have to spend the right info if not then in the future those inserts don't buy them anymore because you can't work on it.

make him a phone call and tell us directly by expressing your doubts, if it's not a who's cheating on you, he has to give you some answers.

 

[marman]

In fact, I think it's even more correct because they respect the evidence I did after trying the initial parameters of the representative. (s1500,f2500,z0.25 and the finish already ' improves a lot) also because with its parameters in sanding the inserts last me 1 piece approximately or a little more', grafting 1mm in total per piece, and I do not know if it is normal having a cut with inserts specially created to work steel.
Anyway, I wanted to make a further call to expose my doubts after the trials I'll see what he's gonna tell me... I hope I can solve this situation as best as possible, even because with the stax from now on I will have to deal probably daily and I would like to work the right way and not always wrong.... !
hello thank you very kind
