Detection means to enrich and strengthen our experimental study about to join the WTO, the late start of high-speed precision ball screws, face competition in the international market, the product to be innovative, to improve the level of technology, product quality, but also to perfect. Ball manufacturers only pay attention to quickly change product output, output BSH ball screw, do not pay attention to the performance of the experimental study of the situation of the new product. Not only for high-speed ball screw positioning accuracy, noise, temperature, plus (minus) the speed, dynamic stiffness pilot study, more experiments should be conducted to study the reliability of the key which was occupied by the market. Vice ball screw from the original function "Agile province can drive" to "precise positioning", from the "big lead high-speed drive" to "precision high-speed type" is a qualitative leap in product upgrades. Linear servo drive in the field of high speed, when the price-performance ratio, cutting time for a comprehensive analysis of the ratio of air travel time, the acceleration and deceleration of the frequency of appearance, taking into account the energy saving and environmental protection, people pay more attention to high-speed precision ball screw development of. Automobile industry, the development of the aerospace industry for high-speed machining of light alloy and more attention, machining centers, industrial robots, CNC forging machinery, FMS, and all types of CNC machine tools and automated machinery feed drive speed continues to increase. With ball screw machining center, for example, the moving speed of the table in the 1980s only 15 ~ 20m / min, about acceleration 0.5g, 90 years in the early to 30 ~ 50m / min, about the acceleration 1g DFM ball screw, to in the late 1990s reached 60 to 80 min, the acceleration of 1.5g or more, and to promote higher speeds. As the servo feed drive system is an important executive body - ball screw, with their fast and efficient, energy saving, zero backlash high stiffness drive, follow the sensitive, do not pollute the environment and strong adaptability to the surrounding environment and other characteristics SFT ball screw bar, always occupy most linear motion applications market. In order to meet the requirements of high-speed machining, to meet at the same time positioning accuracy, how to further improve the speed of the feed and processing (decrease) rate has become the focus of the current industry focus. 1) ball screw nut and a support system to detect and repair gaps appear when CNC machine tools reverse error, unstable positioning accuracy, when crossing quadrant marks appear, the first to detect screw system has no gaps. Detection methods are: using a dial indicator with the ball on the end of the screw in the center hole, measuring the axial play of the screw, the other dial mobile measurement workbench. Reverse rotation of the screw, observing the two dial indicator reflects the values, confirm the fault location based on the value of different changes.
