Spiral bevel and hypoid gear cutting technology update

摘要

Spiral bevel and hypoid gear cutting has changed significantly over the years. The machines, tools, processes and coatings have steadily advanced to the current state of the art. This article will cover the progression from mechanical machines with complex drivetrains that used the Five Cut method of cutting gears with coolant, to machines with direct-drive CNC technology dry cutting gears by the completing method with carbide and high speed tools. The latest cutting tool materials and tool coatings will be discussed. Production examples from the automotive industry will be provided as well as examples from the gear jobbing industry.
