Hi friends.
Some of you know which is the best method to turning large pieces of Hadfield steels (Manganese from 12% to 18%)?
Tool material?
Tool geometry?
Dry or wet?
Cutting parameters?
Anything else?
Many thanks.

hi dear fiend
tool and machining parameter selection are depend on martial hardness
could you give me hardness detail of your alloy?
No Alexander, in this case doesnt depend of material hardness, because in Hadfiel steel if you take the hardness you can obtain 200HB, but when you machining this steel, the hardness increase by the deformation caused by the tool. This steel is harder when is machining.
What kind of machining do you need to do?
What is the size of the workpiece?
There are many shapes of parts. This parts needs turning and milling operations.
The weigth of the parts may be fron 1 t to 13t.

There is a ceramic insert for CNC machines that uses very hard material. However, there can be no discontinuity in the piece, the tablet will break.
