DEVELOPMENT OF THE UNIVERSAL THREAD-GRINDING MACHINE

There are many available methods for the grinding of thread surfaces. Depending on whether the threads are used as joining elements or whether they are kinematic ones, the dominant requirement being the dimension or precision, they differ from each other by a significant measure. The geometric requirements basically influence the manufacturing process. This lecture primarily deals with the development of concepts of thread-grinding machines for the manufacture of kinematic thread surfaces of high precision. This problem is a real one because, according to present knowledge, no thread-grinding machine tool is commercially available suitable for the universal finishing of the newly developed worm gear drives (e.g. spiroid, globoid). Most up-to-date CNC-controlled thread-grinding machines are suitable for manufacturing a given type of thread surface within a well-defined range of dimensions [3]. The target is to develop a thread-grinding machine suitable for universal adoption
