The accuracy retention of bal screw has important influence on stability and persistence of processing accuracy of CNC. The loading program of Eddy current damper is used to design a testing device for precision preservation of the bal screw to solve the problem existing in simulating the actual working conditions of the screw with large load, sensor data real-time acquisition and so on. On this base, this paper studies the testing method for accuracy retention of the bal screw. The result shows that the testing de-vice has the advantages of largely applied load, high degree of simulation, DUT easy disassembly and assembly, high accuracy, wide application and the testing method can be used to complete the accuracy retention test preferably, and it is of the guiding signifi-cance for the study of similar products’ testing method.
