II. The machine characteristics:

1. Make deep hole from diameter 0.3-3.0mmrapidly (Max drilling speed: 30-60mm/min subject to the various materials and electrodes diameters)

2. Servo motor drive Z axis move rapidly

3. Z axis mounts on linear guide ways for high accuracy.

4. X, Y, Z axis adopt ball screw for moving with high stiffness

5. Special pump with high pressure for drilling

6. Auto depth control helps making blind holes easier
