O How to Clamp a TPDB Plus Insert Clamping an insert to a holder O Put an insert on the tip seat of the holder. As the Pic.1 , push the insert to the v-shaped groove of the holder. Screw and clamp the insert. O Precaution in Drilling Technical Information for TPDB Plus G Changing the used insert to a new one J air / / Pic.2 O Unscrew and separate the used insert from the holder. As the Pic.2 , clean the insert seat. Put a new insert on the tip seat. 0 As the Pic.3 , clamp the insert pushing it with a hand not to separate from the holder. Drilling of angled entrace Drilling of stacked plates Plunging Boring 1. The approach angle between drill and the workpiece at the beginning should be less than 6. 2. Reduce the feed to 30-50% than general cutting conditions at the beginning and the end of angled surface. 1. Gap between the plates could make wrong chip evacuation causing fracture of the drill. 2. Place the workpiece, stacked plates without any gap between each. 1. Irregular cutting resistance in plunging could cause fracture and deformation of the drill. . Boring is not recommended due to wear and chipping in the corner of the insert. O Check Point in Drilling Condition of the clamped workpiece Revolution of the main axis of the machine Condition of the holder Run-out of the clamped drill (Max. 0.03 mm) Condition of supplying coolant (pressure, floconcentration) Chip evacuation O Supply of Coolant Supply enough coolant to the beginning of the hole. Minimum pressure of oil coolant: 5 bar Minimum flow of coolant: 5fi/min 0 Recommended Drilling Method (10D, 12D) Machine a beginning hole with the After machining the beginning hole, replace Result of Result of depth of cut as 0.5D and at 30% lower the pilot drill to a drill for drilling and machine recommended general drilling speed using a 1.5D or 3D drill. in recommended cutting conditions. drilling Drills 37
