We have some new jobs in our shop for machining of split pump casings. We have to face, drill and then threadmill these parts.
Currently we are facing major issues in face milling. We run a 100mm/4" Sandvik R390 cutter with 2040 grade R390-17 sized inserts with 1.6 mm corner radius.
The material is Cast Super Duplex Stainless Steel. Any one have experience facing these types of parts? Our tool life and speed is very less.. VC is close to 30m/min and Fz = 0.15mm/tooth.
I was thinking of using a positive rake round button inserted tool(with single sided inserts) so that i would get more edges and high tool life.
Anyone have any experience which tool brand and grade is best for this kind of application?
Also, note that after drilling and facing, we do some pressure testing, after which we need to further remove 0.001 in off the face prior to delivery.
