wheel manufacturers, grinder machine builders and process engineers. To ensure the successful development of ﬁne grinding of silicon wafers, a large amount of research work is needed. As the ﬁrst of a series of papers dealing with ﬁne grinding of silicon wafers, this paper reports and discusses some experimental work on the effects of
Subsurface damage in grinding silicon ceramics793 Кб. Grinding process is an inherently damaging process since the abrasive grains are forced into the surface.Grinding induced damage was found in the subsurface layers of all the silicon ceramics.
Grinding Machine Parts Silicon carbide ceramic wearresistant cyclone is a common separation and classifiion equipment with the principle of centrifugal sedimentation. It is well known as one of the grinding machine parts. The basic principle of silicon carbide ceramic cyclone is to separate
In this study, a commercial grinding machine (VG401 MKII, Okamoto, Japan) was used to grind the silicon wafers. As shown in Fig. 1, in which a silicon wafer is mounted on the vacuum chuck of a worktable, and a cuptype wheel with abrasive blocks uniformly bonded onto the periphery of the end face is used for grinding.During grinding, the worktable and grinding wheel rotate in the opposite
