本文介绍了用金刚石砂轮磨削氮化硅和硬质合金材料的部分结果，并将其推广到陶瓷-硬质合金复合钻具的磨削。在这些基础实验中，四种不同类型的金刚石砂轮被用于端面磨削工艺。金刚石砂轮因颗粒尺寸、颗粒浓度和结合剂的不同而不同。通过改变加工进给速度和冷却方式等相关影响因素，考察了脆性氮化硅和延性硬质合金两种不同材料对磨削效果的影响。详细讨论了砂轮径向磨损量、磨削力分量、法向磨削力和切向磨削力以及被磨零件的表面质量等因素对磨削效果的影响。
This paper presents selected results of the grinding of silicon nitride and cemented carbide materials with diamond grinding wheels, which will in later research be extended to the grinding of ceramic-cemented carbide compound drill tools. In these fundamental experiments four different types of diamond grinding wheels were used in face grinding processes. The diamond grinding wheels vary by the grain size, the grain concentration and the bonding material. The relevant influencing variables such as the cutting and feed speed and the coolant supply method were varied to investigate the effect on grinding of the two different workpiece materials, the brittle silicon nitride workpiece material and the ductile cemented carbide workpiece material. Some factors, which have significant effects, like the radial wear of the grinding wheel, the components of the grinding forces, the normal and the tangential grinding force, and the surface quality of the ground workpieces are discussed in detail.
