MAPLE GROVE, MN, April 25-Carl Zeiss has delivered an MMZ coordinate measuring machines (CMM) to the Mechanical Drives Division at Siemens AG, supporting the rising quality requirements for wind turbine components.

A wind turbine is designed to convert wind into electrical energy with maximum effectiveness throughout its entire lifecycle. This requires reliable compliance with size, form and position tolerances during production of the moveable parts. This applies primarily to the pinion cages and housings of planetary gears. The axis spacing must fit perfectly; the axis alignment must be absolutely parallel. Only then can good operating characteristics be achieved with a high level of effectiveness.
