3. Center Height Adjustment a) When there are no remaining cores and insert breakage near the center of the drill. This happens when the inner insert is set above the center height. (Fig.7) Fig.7 Insert breakage near the center of the drill How to Adjust (1) Install the drill rotated 180°. Most problems will be solved by this method. (Fig.8) Initial Installation (Inner insert positioned higher than normal) 1S0 R°tatiQn/ (Inner insert positioned lower than normal) Inner Improved Position of Inner Insert Fig.8 How to Adjust (2) If the core diameter becomes too large after the above adjustment, install the drill by rotating 90° counter-clockwise as shown in Fig.9 (outer insert is positioned lower) and adjust the center height by moving the tool in the X-axis direction. (However, this will make it impossible to adjust the cutting diameter.) Caution: In case of installing the drill in the reverse direction (outer insert is positioned above), the hole diameter will become smaller, which may cause the drill body to interfere with the drilled hole. The best solution is to readjust the center position of the turret itself. \\Inner edge Zooming near the center Inner Insert Positioned too Far below Center Fig.9 b) Core with excessively large diameter (More than 1mm) This occurs when the inner insert is excessively below the center. This condition causes poor chip evacuation and an adjustment is required. How to Adjust Install the drill rotating 90° as shown in Fig.10. (outer insert is positioned on the upper side) and adjust the center height by moving tool in the X-axis direction. (However, this will make it impossible to adjust the cutting diameter.) Caution: In case of installing the drill in the opposite direction (outer insert is positioned lower), the hole diameter will become smaller, which may cause the drill body to interfere with the drilled hole. The best solution is to readjust the center position of the turret itself. K49 Drilling
