In connection with the development of the machine-building industry, the requirements for the quality and operational reliability of cylindrical gears have increased significantly recently. Among the finishing processes of cylindrical gears, tooth honing has become widespread. This article discusses the technological possibilities of tooth honing with internal hones. The conducted studies have shown that honing has a high ability to correct the errors of hardened teeth obtained during previous operations (after tooth shaving and after tooth milling). A feature of the tooth honing operation is the achievement of low roughness values and its correct location on the side surfaces of the teeth, which helps to retain the lubricating film on the surface of the teeth and reduce vibro-acoustic activity during operation.

The goal research consists in the analysis and synthesis of technological schemes, processes, tools and equipment for processing of conical gears and precession gears with medium module. A new processing method which allows to intensify the process of processing as a result is proposed. It ensures a required accuracy of processing. The theoretical researches are based on the theory gear drives, theory of involute profiles generation and precession gears, generating machine, tool design theory machine building technology. Methods of mathematical analysis, analytic geometry, mathematical model and 3D computer model are used. The experimental researches were conducted in laboratories of departments of machine manufacturing technology and fundamentals of machines design in the Technical University of Moldova, by using machines and technological equipment for machining and testing. Experimental data processing were accomplished using approximation methods and mathematical statistics.

The conditions of engagement of grinding wheel with teeth of the cylindrical wheel when intermittent profile grinding are considered in the paper. There are investigated the possibilities of reducing the thermal stress of the grinding process by means of use of highly-porous abrasive wheels, limitation of specific speed of metal removal and sector sequence of teeth grinding.
