1、离散磨料研磨技术与固结磨料研磨技术摘要：本文简要介绍了研磨及磨料的一些基本知识，着重介绍了离散磨料研磨技术与固结磨料研磨技术的研究背景、原理及性质特点等，并对两者进行了比较。一研磨研磨是一种重要的精密和超精密加工方法，内于其不断发展善，定义也在不断地变化。早年德国的经济加工协会曾给研磨定义为：研磨是一种加工方法，在工件和工具之间无强制导引，利用研磨剂，在不断变更方向的情况下相互滑动。这个定义是较为原始的基本定义，没有体现出研磨的特征。所以，后来有人给研磨又下了定义：用研磨工具和研磨剂从工件表面上磨去一层极薄的金属，使上件表团达到精确

2、的尺寸、准确的几何形状和很低的表面粗糙度值，这种精密加工的方法，叫研磨。这个定义强调了研磨的特征，但也限制了加工工工件的材料范围，仅指金属似乎不妥。由于材料科学的进步和发展，非金属材料的大量涌现，其应用日益广泛，所以研磨加工对象也应包括非金属。因而，研磨可以表述为；利用磨具通过磨料作用于工件表面，进行微量加工的过程。Opinionsandsuggestionsontheparty'smasslineeducationalpracticeAccordingtothecentralandprovincial,municipalunifi
