Technical Manual Technical Specifications (4.4 Application Limits — continued) Maximum Tangential Load for KM4X125 Technical Manual To account for load fluctuations in dynamic F (mm) conditions, a force multiplier of 0,6 to 0,8 should be used. L1 = Distance in millimeters from tool tip to face of clamping unit or spindle. F = Distance in millimeters from tool tip to centerline of taper. P = Maximum static tangential force in newtons. L1 (mm) 8000000 P= √(0.89L1)2 +F2 4.5 Application Limits • Example Maximum Tangential Load for KM4X63 F (mm) 160 L1 (mm) 1700000 Equation provided on page C15 for KM4X63. P= 3(0.81L1)2 +F2 (Only for KM™ and KM4X™. Varies by system and size.) 1700000 P= = 23889,5 N Maximum static tangential load. 3(0,81 * (70))2 +(43)2 Apply a factor of 60–80% to account for dynamic conditions 23889,5N * 0,6 = 14333,7N experienced during actual cutting. 60% is used in this example as a worst-case scenario.
