Book description. Handbook of Ceramics Grinding and Polishing meets the growing need in manufacturing industries for a clear understanding of the latest techniques in ceramics processing. The properties of ceramics make them very useful as components—they withstand high temperatures and are durable, resistant to wear, chemical degradation, and light.
Finishing process such as lapping and polishing are required [B.P. Bandyopadhayay, H. Ohmori, A. Makinouchi 2006].In single side grinding with lapping kinematics, the workpiece will be in contact with the grinding wheel during the whole process with constant pressure [Doi, T., Uhlmann, E., & Marinescu, I. D. (Eds.) 2014].

Kinematics of the ELID grinding with lapping kinematics. The study will be conducted on the Melchiorre Machine (210-3P). This machine has two lower wheels and one upper spindle. Because this experiment is for a single-side grinding, some modifications needed to be implemented. Trajectory
Lapping of plane surfaces is the technology which allows achieving high surface quality. Kinematics of lapping has the main effect on the flatness of active plane of the lapping tools as well as on the quality and flatness of the machined surface. Lapping machines can be used for grinding without the chuck-related problems as encountered in conventional surface grinding.

Lapping is a process used where the surface finish, flatness, or parallelism of the workpiece must be held to very close tolerances. Professional lapping services can achieve a flatness rating of 6 millionths of an inch (0.000006″), parallelism tolerances of ten-millionths of an inch (.00001″), and surface finishes to 0.6Ra. using special ...
periment includes double-side lapping machine, acid etching machine, caustic etching machine, double-side grinding machine, single-side polishing machine and geometric parameters testing equipment. The polishing treatment is carried out in a state in which the polishing pad is in good condition and the polishing machine is sufficiently heated. 2.2.
Some technologies possess the advantages of both lapping and grinding. ELID-lap grinding has the advantage of using micrograin-wheels above #10000 and can be used on existing lap machines (Itoh et al., 1998). Simultaneous double side grinding (SDSG) is believed to be as effective as lapping in waviness reduction (Li et al., 2006).
Sometimes, single side grinding is preferable over surface grinding, because it has the ability to produce flat surfaces. However, the manufacturing cost is still high because of the high tool wear and long machining time. Additionally, most of these grinding processes are followed by a lapping process.

Fine grinding is one of the grinding operations that uses the face of the grinding wheel, but also uses the kinematics of a lapping operation. Fine grinding has a constant pressure between the workpiece and the grinding wheel [7]. This project will focus solely on this operation and will be explained extensively later on.
