Wind Power Industry Solution - Wind Power Wheel Hub Processing Solution

With the advancement and improvement of wind power technology, as well as more and more countries recognizing the importance of sustainable energy, the wind power industry has experienced rapid growth. In recent years, driven by global investment, the industry market has achieved an annual growth rate of 29%. In the foreseeable future, it is expected to continue double-digit annual growth.

The wind power industry continues to innovate and grow, and the challenges of metal cutting encountered in processing and production, such as wheel hubs in wind power components, have also emerged. Due to the fact that the hub is one of the important components of wind turbines, its structure and stress deformation are complex, which will directly affect the normal operation and service life of wind turbines. Therefore, it has the characteristics of high strength, good reliability, long fatigue life, and strong vibration absorption to meet the operating conditions of -20~-40 ℃. The common material is cast low-temperature high impact toughness ductile iron. Wind turbine wheel hubs have a huge volume and generally have a long processing cycle. How to achieve high productivity processing and reduce costs, Dahong has provided such a solution.

The main machining types for wheel hubs are milling and drilling. The DoTriple Mill series milling cutters from Teclo are highly suitable for wheel hub milling.

The 8-angle and 16 angle blades adopt a groove positioning structure to improve clamping rigidity. The optimized blade structure design can meet the processing of stainless steel, high nickel alloy, and high chromium alloy. The concave edge design can ensure the generation of chips during deep cutting, which are easy to discharge and reduce chip residue. The polished blade design of square and octagonal blades can be used for precision machining to expand the application range, with unparalleled economy and universality.

Of course, the more obvious improvement in efficiency lies in drilling, which usually requires drilling nearly 200 holes for the wheel hub. Kyocera's interchangeable tip Magic Drill DRV has better stability and higher strength.

Featuring a unique chip removal groove design, the 6D deep hole machining also has smooth chip removal performance, which can effectively control the flow of coolant and improve chip removal. By combining CVD (outer edge) and PVD (inner edge), high production efficiency and long service life processing can be achieved. When processing the connecting holes of the wheel hub joint surface, significant improvements in production efficiency and stability can be obtained, and the processing cost of each hole can be lower. In this sequence, the feed rate can exceed 400, which means that one hole can be processed in less than one minute.

By using the above products correctly, wheel hub processing can improve efficiency by more than 50%.
