Note: If precision is no problem, then you can re-testing under screw beating, For now the truth is there is no better way to detect, and it says that even the most basic detection method is the most effective. As for how the election screw, in general you have to determine the accuracy of Foshan ball screw, fixed after a good ball screw to determine the weight of Suzhou, the motor speed there is the walking distance, which will be good after basically screw diameter models to determine the and then determining the preload, the preload grinding stage should be P2 or P3 is no gap of light or medium preload preload ball screw and so on, this is no way to use the instrument to detect. Fourth, good synchronization due to the smooth movement, responsive, no blocking, no-slip, the same set of ball screw drive system with the children while the same parts or devices drive a child, you can get very good synchronization effect. Fifth, high durability at a ball rolling contact were hardened (HRC58 ~ 63) process, and the precision grinding and recycling system is purely rolling process. Sixth, high reliability compared with other transmission machinery, hydraulic, ball screw bumper transmission failure rate is very low, ball screw repair and maintenance is also relatively simple, just for general lubrication and dust. It can be operated without lubrication on special occasions. Seven, no backlash and high rigidity ball screw drive system using the groove shape Gothic (Gothic arch), make contact with the ball with the groove in order to easily achieve optimum operation. If the addition of an appropriate gap preload ball screw Guangzhou, eliminate axial ball can have a better rigidity, reduce ball screw nut screw between elastic deformation, to achieve higher accuracy.
