Verify the recommended conditions for each boring bar as cutting conditions for internal machining will vary depending on the length of overhang. y For effective use of large corner radius By setting the depth of cut smaller than the corner radius value, notching during cutting of heat-resistant alloys can be greatly reduced. Corner radius>.5 x Depth of cut Depth of cut: 0.6mm. Corner radius over 0.9 is recommended. POINT A smaller lead angle is the key to reduced notching.
