Sustainable Wind Power Generation Depends on Wenzel CMM Coordinate Measuring Machines

Gear Measurement Wind Power Applications
Creating more efficient, sustainable energy  sources is vital to reducing the use of fossil fuels as the primary source of power generation. 

Making Wind Power generators more reliable and efficient is dependent on manufacturing and refurbishing the giant gears and gear boxes that convert the wind into energy. 

Power generators built for Wind Power applications have very tight tolerances for dimension, shape and position of movable components. These tolerances need to be precisely followed for the wind turbines to generate efficient power and for the life of the turbines and gearboxes inside them. 

Wind Power Generator Gear BoxWind Turbine Gears get exposed to heavy environmental changes from temperature fluctuation and high wind speed to foreign object damage and corrosion.  Refurbishing and refinishing wind turbine gearboxes can cost more than $300,000 after just a few years in service. 




CMM Coordinate Measuring Machines Are Used in Gear Manufacture and Refurbishing

So, ensuring the gears maintain tolerances and are properly maintained is vital to sustainable energy production and wind power generation.

Wenzel Gear Inspection


When gears are inspected before refurbishing and during original manufacture accurate inspection is done using CMM Coordinate Measuring Machines.

Without the knowledge of exactly what damage has been done the gears can’t be refurbished properly. The only way to get this data is with advanced metrology technology and CMMs.




Wenzel LHF is a Vital Component is Wind Power Gear Inspection

Wenzel America’s LHF CMM is a highly precise and dynamic CMM with an extremely large measuring range used for Gear Measurement in Wind Power  applications. The LHF CMM also offers excellent access and great mobility. By adding specialized, custom combinations of touch and scanning sensors the highest accuracy is guaranteed. 

Our CMM coordinate measuring machines and technology support manufacturers of wind turbine for testing and measuring the critical dimensions of gears necessary for sustainable, green, Earth-Friendly energy production worldwide.

What Everybody Ought to Know About the History of CMM Coordinate Measuring Machines

The development of the very first CMM Coordinate Measuring Machine is surprisingly controversial. 
Research shows the development of modern 3-axis machines started in the early 1960s as direct descendants of modern 2-axis metrology machines invented in the 50s in various military defense industries.
The very first 2-Axis universal measuring machine is believed to have been developed by the Sheffield Corporation in the mid to late 1940s. The YZ Machine, as it was called, was used to measure the shells of Hydrogen bombs at a national laboratory in Oak Ridge, Tennessee. The top secret nature of this project leaves us with little actual data about the machine though.

Then in 1957, the Moore Tool Company of the United States introduced the Moore No. 3 Universal CMM Coordinate Measuring Machine aka the M3.

In the early 1960s, Digital Electronic Automation S.P.a of Italy and Ferranti of Scotland, UK both developed 3-Axis CMM coordinate measuring machines. There is controversy over who introduced the first 3D CMM, but the fact is that whoever did it first, today’s CMMs are the direct descendants of this leap forward in CMM Coordinate Measuring Machine technology.
The DEA machine was a Portal Frame CMM with Hard Probe.  While, Ferranti Metrology’s machine was a Cantilever CMM with Digital Read Out and Fixed Probes. DEA introduced their C.M.M. just a few months prior to Ferranti.
