AS B266-1968

Relates to gear hobbing machines having a worm driven table or chuck for producing precision gears of 3 ft diameter and smaller. Machines in which the table is driven by means other than a worm, or in which the hob saddle is traversed by means other than a screw, shall comply with the requirements of this Standard so far as they are applicable. Certain tests may have to be varied to suit the particular form of mechanism adopted. Such tests should be devised to ensure the production of gears of equivalent accuracy and should be agreed between the manufacturer and the inspecting authority.
