die making company in the United States to offer machined nicks. The dieboard is located using the die C/L notch. A CNC program specifying nick width, depth, and location is created to drive the machine.
Nick location is etched on the die so that the press operator can see nick location after ejection rubber is applied. This ensures that if any nicks need to be added the press operator has visual location of current nick location. Diamond nicking wheels are used to provide precise and repeatable nick depth and width.
