Hobbing – the standard technology for external gears<\/h3>\n

Hobbing is the most established and widely used method for producing external gears. In this process, the rotational axis of the tool and the workpiece typically intersect at an angle of between 45\u00b0 and 135\u00b0., meaning the axes are crossed.<\/span>\u00a0<\/span><\/p>\n

Technological basics:<\/h4>\n
    \n
  1. The hob resembles a worm with axial flutes that creates cutting edges, known as cleats. <\/span>These are relief-ground to produce a clearance angle.<\/span>\u00a0<\/span><\/li>\n
  2. Cutting speeds are based on the hob diameter and its cutting speed.<\/span>\u00a0<\/span><\/li>\n
  3. The feed rate is measured in mm per workpiece revolution.<\/span>\u00a0<\/span><\/li>\n
  4. In gear technology, the hob behaves like a worm gear with a 90\u00b0 axis angle.<\/span>\u00a0<\/span><\/li>\n<\/ol>\n
