5. Adjust Closing Speed & Force
a. The Closing Speed of the Gripper Finger is adjusted using the Needle
Valve located on top of the right Solenoid Valve.
b. The Closing Force may be adjusted from zero up to about 20 grams using
the Front Panel Vacuum Regulator Control located to the right of the Die
Eject Speed Control. The closing speed is a function of the Needle Valve
Setting and the Vacuum Force Control.
6. Adjust Vacuum.
a. Rotate the Regulator Control Knob on Front Panel clockwise to increase
the vacuum, thus increasing gripper pressure.
Replace Gripper Fingers
The Gripper Fingers are locked in the Gripper Arms by #2-56 set screws pushing on a
1/16-diameter ball bearing at the tip. The ball minimizes the tendency of the needle
moving when the setscrew is tightened.
The Gripper Finger is the same diameter as a Die Ejector Needle, so a discarded Die Eject
Needle may be used if the Gripper Finger needs to be replaced. While not essential, a
soft vinyl sleeve pushed over the Gripper Finger makes a very soft die contact surface.
