未来理想磨削技术展望

Prospect on ideal grinding technology in the future

  • 摘要: 砂轮自锐是磨削加工的特有性能。然而,在磨削加工中砂轮的自锐性普遍未得到充分利用,致使砂轮在服役期内力热持续上升、磨削质量多变、砂轮频繁修整、磨削效率低、难以持续加工等,不适用于未来生产需求。对此,分析了影响磨削的砂轮结构、磨削机理、磨粒状态、受力状况、微观磨损、自锐机制、胎体性能及磨削力热;探讨了砂轮钝化磨损与锐化磨损之关联等。同时,基于现代科学技术的发展,特别是信息通信、人工智能、激光加工及传感技术的进步与应用等,创新地提出了未来之理想磨削。磨削过程中,设法保持砂轮表面钝化与锐化相互制约,平衡与协同,有利于砂轮不修整、长时、稳定磨削。理想磨削不仅可提高磨削效率,节约资源、能源,而且有利于磨削加工向高效、绿色、低碳清洁生产方向发展。

     

    Abstract: Wheel self-sharpening is a unique characteristic of grinding processing. However, in grinding processing, the self-sharpen property of the grinding wheel is generally not fully utilized, resulting in the continuous rise of force and heat during the grinding service period, the variability of grinding quality, the need for multiple dressing, low grinding efficiency, and the inability to sustain grinding, which is not suitable for future needs. Accordingly, the grinding wheel structure, grinding mechanism, abras state, stress condition, micro-wear, self-sharpening mechanism, binder performance, and grinding force and heat that affect grinding were analyzed. The relationship between wheel dull wear and sharpening wear was also explored. At the same time, based on the development of modern science and technology, especially the progress and application of information communication, artificial intelligence, laser processing, and sensor technology, an innovative ideal grinding idea for the future was proposed. During the grinding process, try to keep the blunt wear and sharpening wear of the grinding wheel in mutual restraint, balance and synergy, so that it is for the grinding wheel to grind stably for a long time without truing. ideal grinding can not only improve grinding efficiency and save resources and energy but also facilitate the development of grinding processing towards the direction of efficient, green, and low-carbon production.
