Hi,
I had to mill small slot with 3mm diameter 3 flute carbide endmill and the DOC was 3mm as well. Material Aluminium most likely 6063 T6. No flood coolant in use, just compressed air to blow the chips away. It didn't end up well, I broke the endmill due to chip welding and clogging it. I checked the feeds and speeds by G-wizard and even the lowest setting with limited 7000RPM gave 160 mm/min. I used actually 130mm/min to be safe but didn't help. So my question is, is there any chance to make this work with plain compressed air? Maybe with lower rpm.
Thank you in advance.
