introduction：1. The first is the ball screw that drives the sensor，Due to the lead screw if there is a gap in the future to make experimental data，It will directly affect the maximum deformation and elongation after fracture。Some of the current electronic universal testing machines on the market are usedTThe shape of the popular screw，In this case, the gap is relatively large，Second, the friction force is relatively large and the service life is short，Jiangdu open source testing machine
