Deep Hole Drilling working principle
Check whether the size and datum mark of the workpiece are correct
The accuracy of X and Y axes shall be ensured during calibration
First move the machine tool to the side of the dividing line. When the relative distance is observed visually, switch to the handwheel operation and the moving speed must be controlled as shown in 10
The horizontal edge of the drill bit is aligned with the center of the hole to drill a shallow hole, and visually check whether the orientation of the shallow hole is correct
Drilling can be carried out after the test drilling azimuth accuracy is required
Conduct quality inspection, including aperture size, position accuracy, etc
