While stocks last. Cutting data Movie Machining details: 1. Conditions must be: rigid machine conditions and excellent holders (shrinking holder). 2. The stated standard values based on interpolation milling (including corners). 3. Coolant with MMKS [MQL (mist)] or air blow. 4. When dipping in Z-axis, you have to reduce the feed speed by 40-60%. 5. The standard values refer to the length l3 of 3×D. For deeper applications please adjust Vc/ap/Vf for the conditions. 6. In order to achieve ideal cutting results you have to consider your local operating conditions. 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
