 CNC machine tools as ball screw feed drive chain, and its assembly in the form of a decision of the CNC machine tools and precision positioning accuracy, but also affect the smooth running of the feed axis interpolation. First, the ball screw installation form and force control machine axis common screw support are the following forms: 1, one end fixed - freedom screw end fixed at one end and the other end free. Fixed end bearings withstand the axial and radial forces, which supported a small way for the trip or for a short screw machine screw manufacture of closed loop, because the mechanical positioning accuracy of this structure is the most unreliable, Especially for large aspect ratio screw (ball screw relative elongated), heat denaturation is obvious, 1.5m long screw in the cold, variation 0.05 ~ 0.10mm is normal under different thermal environments. However, due to his simple structure, easy installation, and many high-precision machine tools are still using this structure, but the grating must be installed, using closed-loop feedback. 2, one end is fixed - the other end of the support screw one end fixed and the other end of the support. Fixed end while axial and radial forces; supporting end only radial forces, but also for the small amount of axial float, can reduce or avoid bending due to the weight of the emergence of the screw, and screw the thermal deformation can be freely elongation to end. The most widely used such a structure, the current domestic small and medium CNC lathes and vertical machining centers, are using this structure. 3, fixed at both ends of the screw fixed at both ends. Fixed end bearings can withstand axial force, this support, it can be applied to the appropriate preload screw, screw improve bearing stiffness, thermal compensation can screw portion is deformed. For large-scale machine tools, heavy-duty and high-precision boring and milling machine is often used such programs. But screw supply, adjust this screw more complicated, if the ends of excessive preload screw experts, will lead to the final stroke ratio designed screw stroke is longer than the design pitch pitch too big. If both ends of the lock nut preload is not enough, can lead to the opposite result, and prone to machine vibration, reduced accuracy. So, when this type of screw disassembly must be adjusted in accordance with the original manufacturer's instructions, or with the instrument (dual laser measuring instrument) adjustment. Ball zero backlash and high rigidity CNC machine tools, IT and semiconductor equipment requirements for the drive screw zero backlash, minimal elastic deformation (high rigidity) and high-smooth feel, through our specially designed to achieve this requirement. Ball (ball screw) using pre-applied pressure to achieve high rigidity CNC machine and the reproducibility of the whole trip. But too much preload will increase operating torque. Thus increasing the friction torque will generate heat and reduce life expectancy. Through a special design and manufacturing process, to provide you the best of a ball screw - zero backlash and low heat loss.
