Abstract

Small machine tools and their components are persistent topics of research. Effective miniaturisation usually requires a complex integration of various functions into a reduced number of components. The concept presented here constitutes a highly miniaturised grinding module named GrindBall. This concept combines a three-dimensional magnetic bearing with a fluidic drive system to embody a micro grinding module with contactless tool positioning and drive. The grinding tool consists of a sphere with an abrasive surface that is able to perform a shaftless micro machining, allowing novel grinding kinematics on hard and brittle materials, such as glass and ceramics. Due to its size and working principles, this concept is specifically developed for micro grinding applications in small machine tools.
