Bone Screw Performance TesterPBSC-RP30 Testing Instrument is a multifunctional integrated instrument developed for the performance determination of medical bone screws. It can perform tests such as bone screw driving torque and self-tapping performance. The bone screw performance tester is widely applicable to medical device testing institutions, medical device manufacturing enterprises, and other units.

Bone Screw Performance Tester

Technical Advantages

● Open structure, full touch screen, user-friendly human-machine interface operation, multiple curve drawing modes, making the testing process clearer

● Utilizes precision micro-stepper motor drive for smoother transmission, lower noise, more accurate positioning, and better repeatability of test results

● Imported custom high-sensitivity load cell, imported (TBI) lead screw ensures precise displacement

● Professional high-performance imported control system controls dual Panasonic servo motors for coordinated action

● Professional software design, fully automatic measurement

● Simple and easy to operate, highly simplified control system handles all complex settings in the background, one-click start

● Professional fixtures suitable for different testing modes

● Built-in dedicated calibration program, convenient for metrology and calibration departments (third-party) to calibrate the instrument

● Supports data export and Office software, combined with an optimized comprehensive data processing system

● Diversified functions, one machine achieves: pull-out performance, self-tapping performance, driving torque, torsional performance
