Automated features make the dimpling process more repeatable
and easy to use. Tools are raised and lowered at the touch of
a button; dimpling force, damping force, fine balance, and Z
offset (termination point) all are set from the front panel.

Four factors improve the termination accuracy:

1. Non-Contact Position Sensor
2. Tool Phase Sensor
3. No external measuring device
4. Magnetically coupled arm damping
