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, generally you should determine the precision ball screw, will be determined after a good weight-bearing ball screw selection method, the motor speed there is the walking distance, which are given after a good model essentially determines the diameter of the screw , and then determining the pre-press, pre-press grinding stage should be P2 or P3 is no gap Light preload or pre-press, etc., this is no way to use the instrument to detect. Ball Screw directly affect the accuracy of CNC machine tool positioning precision ball screw, ball screw precision parameter, which lead error machine tool positioning accuracy impact on the most obvious. 1/3 ~ 1/2 General set screw in the preliminary design of any 300mm stroke volume variation should be less than the target set position V300p positioning accuracy values ??determined in the final checking of the accuracy. Lead screw selection is generally based on the design goals of rapid traverse speeds up to vmax, maximum speed nmax and the motor and lead screw drive servo motor to determine the ratio of i. Usually by the rated dynamic load of ball screw design to determine the dimensions of the ball screw. Dynamic load rating refers to a group of the same size ball screw after running a million times, the ball screw (threaded surface or ball) 90% non-axial load fatigue stripping injury (pitting) is used. Minimum axial load of rail friction action under the table and workpiece, calculate the maximum axial load is the maximum load machine ball screw driving force, it is cutting force in the axial direction of the force of the ball screw and the friction of the guide rail (where friction is caused by both rail table, the workpiece, the total weight of the jig and the cutting force of the three components in the vertical direction of the guide rail. Selecting a Screw mounting screw support, including ways and wire special bearing selection bars, ball bearing different ways to screw stiffness, rotary precision, critical speed has a great influence, generally based on the length of the screw, rotary precision, stiffness requirements and speed to select different installation methods. tbi ball screws | ball screw | Han desk transmission machinery provided by the Dongguan City, South Korea Taiwan Transmission Machinery Co., Ltd., Dongguan City, Transmission Machinery Co., Ltd. of Korea and Taiwan (www.dghantai.com) (www.hantai168.com) machine tool accessories in this field. devoted boundless enthusiasm and passion, Korea and Taiwan transmission machinery has been customer-centric, the concept of creating value for customers, quality, service to win market, and sincerely hope to cooperate with the community to create success, to create brilliant.
