TBI Ball Introduction: definitions and functions TBI ball screw is on machine tools and precision mechanical transmission elements most commonly used, and its main function is to convert rotary motion into linear motion, or to convert torque into axial forces repeatedly , while both high-precision, reversibility and high efficiency. TBI ball screw is the rotary motion into linear motion, or linear motion into rotary motion of an ideal product. Spot TBI Specifications: C5 / C7 precision; ￠ 06-- ￠ 80 Ball Shenyang spot wholesale (end machining cycle 5-7 days, C5 Accuracy: E = 0.018; C7 accuracy of E = 0.050) specifications are as follows:. SCI Type : Specification covers over to the outer diameter of the screw shaft 16 --- 80-speed silent type S Type: SFS-type specification covers over to the screw shaft outer diameter 12-100, DFS type specification covers over to the screw shaft outer diameter 16-100 high-speed heavy Type V Type: SFV type specification covers over to the screw shaft outer diameter 12-80 DFV type specification covers over to the screw shaft outer diameter 15-80 I type: sub SFI and DFI specification covers over to the screw shaft outer diameter 16-80 U Type : SFU specification covers over to the screw shaft outer diameter 12-100 DFU specification covers over to the screw shaft outer diameter 16-100 T Type: sub SFT and DFT specification covers over to the screw shaft outer diameter 20-80 E Type: SFE specification covers over the outer diameter of the screw shaft to 16-50 M (milling only): Specification SFM03205-4, SFM0325T-4, DFM03205-4, both left and right DFM0325T-4 spin. SFK Type: Specification covers over to the screw shaft outer diameter 4-16 BSH Type: Specification covers over to the screw shaft outer diameter 8-25 XSV (grinding stage shaft finished goods) Type: XSVR01210 series, XSVR01510 series, XSVR01520 series, XSVR02010 series , XSVR02020 series characteristics of a TBI ball screw, lead screw and sliding between TBI compared to the screw shaft and ball screw nut has a lot of balls in the rolling movement, they are able to get a higher efficiency of movement. Compared with the previous slide screw vice drive torque reaches 1/3 or less, that the power required to achieve the same results as using the rolling motion of screw vice 1/3. Helpful in saving. 2, high-precision ball screw to ensure that TBI is manufactured in Japan with the world's highest level of consistent production out of machinery and equipment, especially in the grinding, assembly, inspection of the process plant environment, temperature and humidity were strictly controlled Since sound quality management system so that accuracy can be fully guaranteed. 3, the micro-feed may TBI ball screw ball movement because it is so very small starting torque, does not appear as a sliding motion creeping phenomenon, to ensure accurate micro-feed. 4, no backlash, high rigidity
