The Importance of CNC Machining in the Green Energy Industry

In today’s energy sector, CNC machining is playing a vital role. As a key support for modern society, the energy industry requires advanced equipment to ensure continuous energy production. The application of CNC machining in the green energy industry has brought new opportunities for its development.

1.Wind power generation and CNC machining

Wind energy production places high demands on component durability and precision. CNC machining plays an important role in wind power generation, enabling the manufacture of components that withstand enormous pressures and high precision.

The production of wind turbine blades requires metal and carbon fiber machining, while giant bearings in the adjustment mechanisms also rely on CNC machining for high-precision manufacturing. Multi-purpose lathes are often used to machine components such as gears, gearbox housings and rotors. For wind turbines and windmills, CNC machines can process materials such as reinforced carbon fiber plastic or fiberglass. The profile of the rotor blades is similar to that of aircraft blades and requires high precision.

2.Solar Energy and CNC Machining

In addition to the solar panels themselves, there are various parts that require precision manufacturing, such as frames, back rails, and bracket rails. Milling and drilling machines are ideal for such projects, and many companies market their CNC machines as being specifically designed for producing solar panel parts. Even large solar panel production lines contain multiple types of CNC processes, such as cutting and drilling, but also require multiple non-CNC processes to work simultaneously with operators.

Because production lines can be very large and fancy, companies such as Fanuc have been offering versatile robotic arms that can handle a variety of shapes with more flexibility and workspace efficiency. Similarly, companies such as Beam cut are offering software specifically designed for solar panel manufacturing that streamlines the process so that only one person can operate it. This is one of the ways CNC frees up space and labor utilization.

Solar panel manufacturers often use turning centers and wire EDM machines to create frames and housings. Plasma and fiber laser cutting machines are often specialized for solar panel manufacturing, and various lasers are often used to segment the panels themselves. Similarly, companies like Protolabs combine CNC machining and 3D printing to produce solar panels. This does suggest there may be room for hybrid manufacturing in the solar industry.

3.Hydropower

Hydro turbines and generators are more than just big machines. They also need to be resistant to pressure and water damage, and made from metals with the same qualities, often using carbon and stainless steel parts. Companies around the world use CNC technology to produce a variety of components, from simple shafts and bushings to hydro turbine casings, impellers, and covers.

It involves the usual turning, line boring, and milling, but is often done on a massive scale, depending on the needs of the factory. For reference, Canyon Hydro in North America uses a 7-axis CNC milling machine capable of manufacturing Pelton and Francis hydro turbines up to 16 feet in diameter and weighing up to 25 tons. The CNC machine can correct small (but potentially impactful) imperfections in the turbines. It’s one of many machines in their manufacturing center. On a larger scale, Voith Hydro’s York plant machines workpieces up to 42 feet (12.80 meters) in diameter and weighing more than 350 tons (317.5 tons).

In addition to turbines, CNC milling and other machining techniques are used to develop gates for dams and hydroelectric plants. In some cases, the development of various CNC machine tools has allowed these parts to be produced on-site rather than shipped from distant factories.

The green energy sector in general has benefited greatly from CNC machining and modern technology. We have only scratched the surface of their capabilities, but there are already many applications, benefits, and use cases.

4.Summary

In general, the green energy industry has benefited greatly from CNC machining and modern technology. The application of CNC machining in fields such as wind power generation, solar energy and hydropower has improved the quality and efficiency of energy production tools and parts, providing strong support for the development of the green energy industry. With the continuous advancement of technology, the role of CNC machining in the green energy industry will become more prominent.
