砂轮自动动平衡装置

随着磨床自动化，NC和CNC控制装置的发展，保证高速磨削、强力磨削及高精度磨削设备的能力的充分发挥，延长砂轮寿命、减小机床振动，砂轮的自动平衡装置尤为重要。文中介绍了加水平衡式、氟里昂平衡式及SBS重块平衡式多种自动动平衡装置的原理，分析了各自的优缺点，预测了发展方向。

Along with the development of automation, NC and CNC control appliances of grinding machine, in order to give full play to ability of high-speed grinding,brute force grinding and high-precision grinding machines, prolong life of grinding wheels and reduce vibration of machine tools, automatic balancing apparatus for grinding wheels is especially important. In this paper, principle of various types of automatic balancing apparatuses such as added water balancing type, freon balancing type and SBS heavy block balancing type are introduced, the advantages and disadvantages of each type are analyzed respectively, and orientation of developngnt is forecasted.
