Material: Typically made of high-strength nodular cast iron such as QT400-18AL. It must have excellent fatigue resistance and low-temperature impact toughness.

Thread Accuracy Assurance: The threads are produced using a CNC machining center milling process. Finished products are inspected with go/no-go gauges to ensure thread quality.

Anti-deformation Process: Wind turbine bases are prone to deformation during machining. We adopt a cutting process combining stress relief and coolant-assisted cold cutting, ensuring that flatness after machining is controlled within 0.1 mm per meter.

Surface Treatment: After machining, machined surfaces are typically treated with Dacromet or zinc spraying to prevent corrosion, while non-machined surfaces are coated with high-build epoxy paint.

Typical Customers: Leading wind power equipment companies both domestically and internationally.

CMM Inspection: After the product is machined, laser inspection is carried out and an inspection report is issued.
