how about machining hard parts like 60-65 HRC?If you have the tools...can it be done also in this case?
I have to machine a welded portion (the welding itself is used to obtain a final shape) wich has about 62-65 HRC.I found an aplication from ISCAR,but it takes a huge amount of time to finish the part.I have a 50mm mill in diameter,milling at 40m/min,0.05mm/tooth (5 teeth),and 0.2 mm depth...If I go to 0.4mm depth the inserts begin to brake after about 2 passes...Any suggestions?
Your best bet will be to find an insert or solid carbide mill that is specifically designed for milling of high RC material. I would suggest looking at the high feed cutters for mold and die work. These cutters take very shallow cuts but at very high speed, and are specifically designed for cutting of high RC die mold materials.
