Technical Guidance Technical Guidance Basics of Drilling I Reference of Power Requirement and Thrust Diameter (mm) Cutting Condition Selection Control cutting force for low rigid machine The following table shows the relation between edge treatment width and cutting force. If a problem caused by cutting force occurs, reduce either the feedrate or the edge treatment width. Condition Edge treatment width 0,15mm 0,05mm vc (m/min) f (mm/rev) Torque (N m) Thrust (N) Torque (N m) Thrust (N) 40 0,38 12,8 2.820 12,0 2.520 50 0,30 10,8 2.520 9,4 1.920 60 0,25 9,2 2.320 7,6 1.640 60 0,15 6,4 1.640 5,2 1.100 Drill : 010 Work material: C50 (230HB) High speed machining recommendation When there is surplus capacity with enough machine power and rigidity drilling at normal recommended cutting conditions, we recommend higher drilling speeds.
