tolerances obtainable turning

[Franz 2.0]

Good morning.
being "limited" tolerances for turning and not wanting to go to rectification by question of cost, I ask if:

- outside with steel c45 you can hold fi 14 d6
- inside with brass cw614n you can hold fi 14 h7

Thank you.

I don't think that way. .
x c45 should you also consider overmetal x reclaim?
cmq, if you ask a good supplier will tell you, and cmq you can also look at the classic tables of the unit.

I don't think there's any difficulty for both of us, they're part of the error of a lathe (parallele or cnc that is).
depends (as always) on the "manic" of the lather.
You may have a higher cost attributable to the high probability of scrap, but still feasible both without problems.

for the internal ø14h7, there are the alestors.
so much to indicate the first that indicated me google.. .http://www.novarametalli.it/index.html?lang=it&target=d294.htmlare not overly pushed tolerances

Hello friuldoc
those indicated in the web page are hand alestors
Maybe I would opt for those in the car
hand-handed (for obvious ray)lightly conical and you must have the ability to pass it throughout the length of the piece
the machine should be mounted on the spindle
in the mirror
center tip
12 pre-hole
hole 13.75
alestore from 14 h7

the tolerances indicated are easy to perform
if one can't do it means he does another job
p.s.
use emulsion
drunkenness and scarcagnifica :smile:
Thank you very much

Dearest shiren
I had no doubt about your speech::finger:
in fact I indicated the first alestors I found on the google, only to indicate that there is the tool "already ready" to get that quota with that tolerance, without going to look for it with work on the machines
It is obvious that then you choose the most suitable tool according to the needs, the number of pieces etc. etc.

mbt:tongue::smile:
was just a clarification to your proper intervention
since the friend franz 2.o
to ask such a question
It is obvious that you have no direct or specific experience
It's fair to say that with an alestore you solve the prob.
but we must also address choices
a hug:wink:
