If there is chatter, insert chipping, etc. during machining, alter conditions accordingly. Note 2) Chattering vibration is more likely under the following circumstances. Use a cut and feed per tooth that are at minimum recommended conditions or below. • When tool overhang is long (using a long shank, screw-in type, etc.) • Rigidity of machine, work material or attachment of work material is low • Corner radius during pocket milling Note 3) A type with fewer teeth is recommended when the depth of cut in the radius direction (ae) is .5 DC or more. Note 4) Wet cutting is recommended, when focusing on the surface finish. (Tool life is shorter than for dry cutting.) Note 5) When using under higher than recommended cutting conditions, or for long periods of time, the clamp screw may become fatigued and break during machining. Please change out the clamp screw periodically. L152 INDEXABLE MILLING
