Torsion Spring Torque Testing Machine

Measures torque versus angle for torsion springs and clock springs, giving torque at set angle and spring rate. Used in hinge, switch and automotive component industries.

Specification

The spring leg is held at an arm while a servo motor rotates the opposite arbor through a programmed angle. A torque sensor records the reaction, and the curve identifies rate and maximum torque.

Features

• Servo rotation with angle encoder
• Torque sensor with overload cut-out
• Clockwise and anticlockwise testing
• Arbor sizes to suit spring bore
• Torque-angle graph on display
