Abstract
Nowadays Russian manufacturers of metal-cutting tools for machine-building industry do not offer structures of prefabricated cutting hobs with retrofittable carbide blades for processing of tooth wheels, though usage of retrofittable carbide blades allows to increase significantly working capacity and productivity of the processing. As of today creation of an assembly cutting tool for processing of tooth wheels with the retrofittable carbide blades is a big step forward for machine-building industry. A high quality tool allows warranting for a new equipment and making work of operators more productive. This paper offers a new technical solution providing increase of efficiency of processing by assembly tools with the retrofittable carbide blades made of a hard alloy. Due to usage of progressive cutting patterns division of a margin for straight-line segments and curved sections is performed. This division has a positive impact on cutting hard-alloy inserts and also reduces their wear and tear.
Highlights
Nowadays Russian manufacturers of metal-cutting tools for machine-building industry do not offer structures of prefabricated cutting hobs with retrofittable carbide blades for processing of tooth wheels, though usage of retrofittable carbide blades allows to increase significantly working capacity and productivity of the processing
In accordance with state program of RF “Development of industry and increase of its competitiveness” the task of perfection of structures of the assembly tools for processing of the coarse pitch tooth wheels equipped with cutters made of tool hard alloys with the purpose of a significant increase of productivity and working capacity is essential
Many leading countries such as Germany, Switzerland, USA, Japan develop actively manufacturing of a metal-cutting tool and contribute a lot in their economics
Summary
Nowadays Russian manufacturers of metal-cutting tools for machine-building industry do not offer structures of prefabricated cutting hobs with retrofittable carbide blades for processing of tooth wheels, though usage of retrofittable carbide blades allows to increase significantly working capacity and productivity of the processing. In accordance with state program of RF “Development of industry and increase of its competitiveness” the task of perfection of structures of the assembly tools for processing of the coarse pitch tooth wheels equipped with cutters made of tool hard alloys with the purpose of a significant increase of productivity and working capacity is essential.
