摘要： 提出一种带有粗磨区倾角θ的陶瓷结合剂CBN点磨削砂轮，研究了新型砂轮设计与制备的原理；这种新型砂轮具有磨除率大、加工精度好等优点.分别用不同θ角的砂轮在一系列磨削参数条件下磨削QT700材料的阶梯轴，用超景深显微系统和三维轮廓仪观测工件的表面质量，测量出表面粗糙度，得出偏转角α、磨削深度ap、工件轴向进给速度vf和砂轮速度vs等不同磨削参数对表面粗糙度的影响规律，并且比较了在同一组磨削参数下，3种不同θ角砂轮对表面粗糙度的影响情况.

Abstract: A vitrified bond CBN point grinding wheel with coarse grinding area slope angle θ was proposed， which owned higher removing rate and machining accuracy compared with the conventional wheels. The design and manufacture principle of the novel grinding wheel was studied. Stepped shafts of QT700 were ground using the wheels with different coarse grinding area slope angle θ under the conditions of a series of grinding parameters. The surface qualities of the workpieces were observed by means of VHX1000E microscopic system and Micromeasure system， with the surface roughness measured. The effect of the grinding parameters on surface roughness was investigated， and the surface roughness of workpieces， which were ground using the wheels with different slope angle θ under identical conditions of the grinding parameters，was compared.

Key words: coarse grinding area slope angle, point grinding, grinding wheels fabrication, grinding parameter, surface quality
