Bevel pinion and ring gear production with gleason powercutting~(TM)

摘要

High speed machining using carbide has been known for some decades for milling and turning operations. The intermittent character of the gear cutting process has delayed the use of carbide tools in gear manufacturing. Carbide was found at first to be too brittle for interupted cutting actions. In the meantime, however, a number of different carbide grades were developed. The first successful studies in carbide hobbing of cylindrical gears were completed done in the mid 80's, but still did not lead to a breakthrough in the use of carbide cutting tools for gear porduction. Since the carbide was quite expensive and the tool life was too short a TiN coated high speed steel hob was more economical than an uncoated carbide hob.
