Canyon Hydro expands manufacturing center, turbine machining capabilities

Canyon Hydro announced it has completed a major expansion to its manufacturing facility, including the addition of a 7-axis CNC milling machine capable of fabricating Pelton and Francis hydroelectric turbines up to 16 feet in diameter.

Canyon Hydro is now the only turbine manufacturer in North America with the capability to fully machine Pelton runners from a single casting, Canyon Hydro reported.

The new CNC center makes it possible for Canyon Hydro to machine all surfaces of its Pelton and Francis turbines with much greater precision. Canyon’s Pelton runners are typically milled from a single, stainless-steel casting, the company reported.

The company also rebuilds turbine systems for existing hydroelectric projects. The 7-axis CNC machine can accommodate components up to 36 feet long, 16 feet in diameter, and 25 tons.

CNC machining eliminates the minor imperfections that result when turbines are hand-ground to match a series of templates. Each of those imperfections, however small, impacts the efficiency of the turbine. With CNC, every curve on the turbine precisely matches design specifications, Canyon Hydro reported.

“With this investment, Canyon Hydro has set up the highest standard for turbine quality,” said Richard New, vice president of manufacturing for Canyon Hydro. “Tighter tolerances translate to better turbine efficiency, which goes right to the bottom line for our customers.”

Canyon Hydro’s new CNC fabrication center is the latest in a series of investments. In addition to the 7-axis machine, the new facility houses several smaller CNC machines for milling other turbine components, plus a fully-equipped computer lab for design and modeling, the company reported.

Canyon Hydro is the Waterpower Division of Canyon Industries. The company manufactures utility-grade hydroelectric turbines up to 25 megawatts and rebuilds existing turbine systems to match newer, more efficient specifications.
