The Screwdriver Bit Torsion Testing Machine is a specialized testing device designed to evaluate the torsional mechanical properties of screwdriver bits, which are tool bits mounted on electric drills, screwdrivers, and other fastening tools for driving screws. It is mainly used to determine parameters such as torsional stiffness, torque, torsional strength, torsion angle, and failure torque.
The Screwdriver Bit Torsion Testing Machine is designed to evaluate the torsional stiffness, torque, torsional strength, torsion angle, and other mechanical properties of various screwdriver bits, including:
Power screwdriver bits
Screwdriver bits
Phillips bits
Double-ended bits
Ball-cage-type bits
The machine uses a computer-controlled AC servo system for torsional loading. An AC servo motor and reducer drive the active chuck to rotate and apply controlled torsional force to the test specimen.
A high-precision torque sensor and photoelectric encoder are used to measure torque and torsion angle, providing accurate test data.
The computer control and test software can dynamically display and record:
Torque–Torsion Angle Curve
Torsion Angle
Torque
Loading Speed
Peak Torque
Other relevant torsional test data
The system is suitable for quality control, product development, performance verification, and research of screwdriver bits and related fastening tools.
