大约25年前，恒力磨削概念的发展导致了几种具有重大优点的新磨削原理。传统上，恒力磨削是通过液压元件实现的，这导致了伪恒力磨削过程。CBN磨料也已问世20年，许多研究人员在CBN车轮的修整、修整和选择方面获得并发表了重要的知识。本文介绍了一种在设计、仪器化和车间硬化方面现代化的机器，使理想的恒力循环可与CBN砂轮结合使用，以实现CBN磨料在生产环境中的实际使用和优化。描述的功能包括CBN车轮自适应修整和调节的硬件和原理，以及恒定扭矩的变化

THE DEVELOPMENT OF THE CONSTANT FORCE GRINDING CONCEPT SOME 25 YEARS AGO LED TO SEVERAL NEW GRINDING PHILOSOPHIES WHICH HAD SIGNIFICANT MERIT. TRADITIONALLY, CONSTANT FORCE GRINDING HAS BEEN ACHIEVED VIA HYDRAULIC COMPONENTS WHICH HAVE RESULTED IN A PSEUDO-CONSTANT FORCE GRINDING PROCESS. CBN ABRASIVES ALSO HAVE BEEN AVAILABLE FOR 20 YEARS, AND SIGNIFICANT KNOWLEDGE HAS BEEN GAIINED AND PUBLISHED BY MANY RESEARCHERS IN THE AREAS OF TRUING, DRESSING, AND SELECTION OF CBN WHEELS. THIS PAPER DESCRIBES A MACHINE THAT IS MODERN IN DESIGN, INSTRUMENTED, AND SHOP HARDENED SUCH THAT IDEALIZED CONSTANT FORCE CYCLES CAN BE USED IN CONJUNCTION WITH CBN GRINDING WHEELS TO ENABLE THE PRACTICAL USE AND OPTIMIZATION OF CBN ABRASIVES IN A PRODUCTION ENVIRONMENT. FEATURES DESCRIBED INCLUDE THE HARDWARE AND THE PHILOSOPHIES FOR ADAPTIVE DRESSING AND CONDITIONING OF CBN WHEELS, THE VARIATIONS OF CONSTANT
