500 N·m Screwdriver Torsional Strength Testing Machine

The 500 N·m Screwdriver Torsional Strength Testing Machine is a high-precision torsion testing system designed to evaluate the torsional strength and mechanical properties of screwdrivers and other torque-loaded materials or components. With a maximum test torque of 500 N·m, the machine uses a high-resolution torque measurement system and angle measurement system to accurately record torque and torsion angle during testing.

Application

The 500 N·m Screwdriver Torsional Strength Testing Machine is widely used for torsional performance testing of various materials and components, including:

Welding joints

Spring steel

Steel wire ropes

Steel wires

Electrical wires

Cables

Other metal materials and torque-loaded specimens

The machine can determine key mechanical performance parameters such as:

Maximum Torque

Torsional Strength

Upper Yield Strength

Lower Yield Strength

Torsional Failure Torque

The test data can be automatically collected, analyzed, and printed as detailed test reports, making the equipment suitable for material research, quality inspection, product development, and laboratory testing.
