Conditions must be: ridgid machine circumstances and excellent holders. 2. Reduce the cutting data when you machine with long neck length. 3. The stated cutting date belongs to a neck length of max 4×D and a tapered workpiece of max. 15°. 4. I f the corneradius of the workpiece contour is smaler than 1.5× end mill radius or the worpiece contour ist to steep, you have to reduce the cutting data up to 50% Recommended cutting data for Karnasch solid carbide ball nose 3D – 4 flutes Recommended cutting data for Karnasch solid carbide ball nose 3D – 4 flutes 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
