Im making some hexagon nuts out of 310 stainless steel, the starting diameter is 35mm and my finished a/f im aiming to achieve is 30mm
Im using a Trishul 2ts polygon milling machine, ive set up the program to take 2 passes at 1.25mm each time and im using tnmg yg3030 inserts with a tool nose radius of 1.2 but burning through inserts really quickly.
My parameters are 0.04 feed rate and spindle speed of 140m/min
Can someone advise on better speeds or feeds or maybe some inserts #industry source
