I'm trying to cut some grooves in 316 with a Fraisa 0.2mm endmill (2 flutes). The catalog only makes recommendations for hardened tool steels 42-60 HRC. With a gear I have capabilities for up to 40 000 rpm, but my test so far has been with: 30 000 rpm, ap 0.02mm, 250 mm/min feed. The mill snapped at the first pass. It's not a diving mill so I'm diving into 0.5mm holes. Anybody have any experience with this?  |
