Hi.
Turning question.
I would like to get to know if anyone have solved the problem with chipbreaking when working with POM (maybe a tradename, but the same as Delrin)?
I have found that roughing can be done good, with a Sumitomo NS-U insert, 800m/min and feed about 1mm/rev.
However, finishing is a problem.
I use Aluminumtype inserts (like Sandvik Coromant Al-type), to make the shining finish with a low Ra-value, but chips are not breaking, and making a lot of problem further on in the production.
Have anyone found an untraditional solution?
