Ball screw determine the main technical parameters: (1) Lead Ph transmission requirements depending on the machine, load size, and transmission efficiency and other factors considered OK. Generally selected, press the machine drive required to determine, the formula is: Ph≥vmax / nmax (10). Where: vmax- fastest machine table feed speed, mm / min; highest nmax- Taiwan ball screw drive motor speed, r / min. In the resolution of the system to meet the control requirements of the premise, Ph should take a larger value. (2) selection of a ball screw nut ball screw for CNC machine tools due to the rigidity have higher requirements, so pay attention to the stiffness of assurance when choosing nut. Recommended by high stiffness required to select a preloaded nut type. Wherein the outer loop of the end of the cannula style double flange nut most widely used. It is suitable for heavy loads drive, high-speed driving and precision positioning systems. And it has a unique advantage in the large lead, small lead and long thread, and more economical. Linear guides and ball screw technology trends and current situation with increasing speed of the machine, the use of linear guides also transformed from sliding to rolling. In China, due to lower manufacturing costs and the reasons the machine speed on the Hangzhou ball screw, slide rails use account for the majority of Zhongshan ball screw, but the use of ball and roller guide rails in the sharp rise in the number of machines. Since rolling guide with high-speed, long life, plus the advantages of pre-press, easy installation, etc., with the improvement of performance and NC machine tool requirements, scroll increase rail use ratio is inevitable. To achieve its high-performance, high-precision machine tools in China's production of ball screws on the drive ratio has been greatly improved. Currently the machine uses a ball screw, a lower domestic price, but also high precision Taiwan, Japan and Europe, and other products. The use of such products tend to have higher requirements for the machine in those processing speed, accuracy, longevity and stability. To increase the productivity of your machine, it is necessary to improve the machine's speed. These machines are widely used HIWIN products. In China, it has started production speed of 60m / min processing center, thus, the demand for high-speed ball screw and linear guide will also have to increase rapidly. HIWIN brand from 1990 began to develop the manufacture of bearings ball screw, already has many years of production history of bearings and ball screws. Recent years, HIWIN also developed a high-speed silent ball screws, roller linear guide, which will provide strong support for China's development of high-performance machines. HIWIN bearing manufacturing technology strengths, this scroll technology, development and production of ball screws, linear guides, spindle unit and used in various parts of the machine almost all the rolling members.
