Ball Screw Torque Tester

The Ball Screw Torque Tester measures ball screw nut torque for screws ranging in length from 8 inches to 15 feet. The screw drive head is at the left end of the machine with the tailstock shown just to the right of the drive head. Torque Rings, which attach to the ball screw nut to prevent rotation with the driven screw, are stored progressively by increasing size on hooks in storage cupboards in the right half of the machine backsplash. Adjustable industrial leveling feet are used as bases for the 14 legs for even and level support. Machine frame is covered by sheet metal plates for a clean appearance.

The Computer Data Acquisition / Control System is placed at the left end of the machine frame. The touch screen monitor located just above the machine drive head shows the same display as the computer monitor (not shown), but responds to operator input via touching screen displayed push-button choices. The test specimen is mounted between the drive dog on the left and the tailstock to the right.
