Max Maag
Max Maag, 1883-1960, of the Maag Gear Wheel Co
The son of a village teacher in Flurlingen at Zurich. He attended the Zurich Polytechnicum and studied machine design at the Oerlikon Co. Soon after, he became a designer at the Kaspar Wust plant. In 1908, he developed the geometry of nonstandard involute spur and helical gears, which enabled designers to avoid undercutting and to increase the tooth thickness. His research led to the development of the Maag system of generating nonstandard involute gears. In this system, he applied the method and machine invented by Samuel Sunderland of Keighley. In 1909 he obtained a patent for cutting nonstandard involute gears based on the application of Sunderland's machine. In 1910 he opened a small workshop to produce non-standard involute gears with modified Sunderland's machines. The first gears cut according to the Maag method were delivered in 1911, and patents were granted in 14 countries. In 1913 he founded the Company Ltd. and remained its managing director until his retirement in 1927. A significant achievement of the Maag Company was the development of the method to grind spur and helical involute gears. It provided the first automatic compensation for wear of the grinding wheel.
