When V slotting, reduce the feed rates by 70%or more. When centre drilling, reduce the feed rates by 80% or more.2) If the rigidity of the machine or the workpiece installation is very low, or chattering is generated, please reduce the revolution and the feedrate proportionately.3) For austenitic stainless steels and hardened steels, the use of non-water-soluble cutting fluide is recommended.<strong>SOLID</strong><strong>END</strong> <strong>MILLS</strong>CARBIDERECOMM<strong>END</strong>ED CUTTING CONDITIONS FOR MIRACLE <strong>END</strong> <strong>MILLS</strong>B260
