I need to tap 2000 m8 and m6 holes in stainless steel on my cnc lathe. I am using G32 tapping cycle. It is the code that mastercam generated. I have tried FEW blue band spiral flute taps. the tap broke after 20 holes. I tried Guhring blue band spiral point. It broke after 2 holes. I have a Emuge tap and a OSG tap. but now im scared that there might be something wrong with my program or setup. I dont want to break anymore taps. I have checked the runout of the drill and tap. they have less than 0.02mm runout. i am using a floating tapping head. i dont have a refractometer to check the soluble oil level. but when i filled the coolant i mixed 10% oil. I am tapping at 300RPM. I am drilling 30mm deep and tapping 20mm deep. is G32 the right cycle for Fanuc OT? What other things can i change to prevent the taps from breaking?
