Abstract: The current cycloidal gear grinders, which machine workpieces point by point, possess 400 low productivity to satisfy the development of national production. In engineering say carved surface being machined depends on two main factors, one is the shape of the cutting tool, another is the relative motion between the tool and the workpiece. By the use of the theory for forming surfaces, the seven ways for grinding cyclo gears have been found in order to choose the best one on the present condition, we take feasibility, machining quality, productivity and economy as evaluating targets. Through comparison, a new method with grinding belt as cutting tool has been selected. It works by way of radial feed, so a whole tooth length of cycloidal gears is ground at the same time. To reduce the experiments, we have discussed the relationship between technological parameters and the results. By using of computer the theoretically parameters have been optimized. Through productive test, it has been testified that the new method can highly increase productivity and decrease cost. So an advanced, practical, radially feeding method orfm finishing cyclo gears with abrasive belt as grinding tool has been developed.
