Abstract

For precise micro-EDM machine tools with high-speed pneumatic spindle, the parallelism between the axis of rotation and the existing Z axis directly determines the machining accuracy of tool electrode and workpiece, so it is necessary to adjust the parallelism between the rotary axis of the pneumatic spindle and the Z axis. Due to the small diameter and low rigidity of the tool electrode, the traditional contact metering method is difficult to apply. Therefore, based on the principle of micro-energy pulse discharge sensing, the diameter and center coordinates of the tool electrode are measured in different tool electrode sections, and the tilt between the pneumatic spindle and the Z-axis is calculated. Based on principle, the posture of the spindle is fine-tuned. This can easily and quickly adjust the parallelism between the pneumatic spindle and the Z-axis. Finally, the parallelism error of the measuring section is successfully controlled within 0.0015 mm.
