If the rpm available is lower than recommended please reduce the feed rate to the same ratio. Use only accurate and highly rigid machines. Decrease the feed rate about 50% from the milling parameters when slot milling. We recommend to reduce the feed rate about 50% when milling in corners. 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
