Ball screw support is a key part of CNC machine tools, in the CNC machine tools play an important role in supporting and fixing the screw, ensuring the screw rotates accurately and operates smoothly, the following are its specific applications in CNC machine tools.
1、Support the weight of the screw: the screw of the CNC machine tool is usually long and large in mass, the screw support seat is used to support the weight of the screw, reduce the sagging and deformation of the screw due to its own gravity, prevent it from affecting the machining accuracy of the machine tool.
2, Withstand axial and radial forces: in the operation of CNC machine tools, the screw will be driven by the axial force from the motor and the radial force generated by the table movement or tool cutting. The ball screw support can withstand these forces and transfer them to the machine's infrastructure to ensure the stable operation of the screw.
3, Accurate axial positioning: screw support seat bearing has high precision axial positioning ability, can ensure the accuracy of the screw in the rotation process of axial position, which is critical for the coordinate positioning accuracy of CNC machine tools.
4, Reduce frictional resistance: screw support seat bearing is usually used in rolling bearings, its rolling friction coefficient is small, can effectively reduce the frictional resistance of the screw rotation. This not only reduces energy loss and improves transmission efficiency, but also reduces the wear and tear of bearings and screws, extending their service life.
5, Optimize lubrication and sealing: screw support is usually designed with good lubrication and sealing system, which can ensure that the bearings work under good lubrication conditions. Further reduce the friction resistance, and prevent lubricant leakage and external impurities from entering, to ensure the stability and reliability of the transmission system.
6, Easy to adjust: screw support seat in the installation process can be adjusted through the adjustment shims or other adjusting mechanism to accurately adjust the position of the screw and preload to meet the precision requirements of the machine tool.
Screw support holders are widely used in various components of CNC machine tools, such as spindles, tables, tool magazines, etc. They are used to support and fix ball screws to ensure high precision and stability of the machine tools. Its high precision, high rigidity and low noise characteristics make it an indispensable key component in CNC machine tools.
