Ball screws are one of the core components of the feed system in CNC machine tools, and their use is an effective measure to improve the sensitivity, positioning accuracy, and prevent creeping of the feed system.
The accuracy and performance of ball screws directly affect the positioning accuracy and repeatability of CNC machine tools. The lead error of ball screws has a significant impact on the positioning accuracy of machine tools.
The accuracy of ball screws is very important as it directly relates to machining accuracy and efficiency. Generally, the accuracy of CNC lathe screws can be divided into grades such as C0, C3, C5, C7, C10, C14, and C16. If high machining accuracy is required, precision-grade ball screws, such as C3 or C5, can be chosen. If the machining requirements are not high, lower precision-grade ball screws, such as C10 or C14, can be selected. Generally, CNC machine tools use ground ball screws with precision grades ranging from C2 to C5.
The choice of ball screw model is also a factor to consider. Common models include short screws, long screws, cylindrical screws, and square screws, among others. Different models and specifications of CNC lathes have different requirements for ball screws.
Therefore, when selecting a ball screw, it is necessary to match it with the lathe equipment to ensure that it can meet the performance and lifespan requirements of the machine tool. At the same time, attention should be paid to the selection and maintenance of other transmission components that are compatible with the ball screw, such as bearings and gears, to ensure the efficient and stable operation of the entire transmission system.
