The three-eared ring-shaped flange piece is a commonly used custom machined component for mechanical transmission, instrument shells, and fluid equipment. Relying on the CNC precision turning and milling combined process, it can complete full-size non-standard customization as per requirements.
The product is overall designed with an integrated structure. The outer ring's ring-shaped reference surface is smooth and free of burrs. Three symmetrical mounting ears are reserved with standard fixed hole positions. The concentricity and flatness tolerances are strictly controlled to ensure the sealing fit after assembly and prevent leakage and loosening problems. The material options include 6061 aluminum alloy, 304 stainless steel, and 45 steel, etc. The surface can be treated with hard anodizing, blackening, polishing, etc. The black anodizing process in the picture has the characteristics of rust prevention, wear resistance, and corrosion resistance, and can be applied in outdoor and humid working conditions.
The entire processing is carried out through one-time clamping on CNC equipment, avoiding size deviations caused by multiple clamping processes. From small instruments with small flanges to heavy-duty ring pieces for large equipment, it can handle all these requirements. It supports custom orders based on drawings or samples, and can adjust parameters such as the inner and outer diameters of the ring body, the number of mounting ears, the hole spacing, and the thickness. Special structures such as sealing grooves and step positioning can also be processed.
It is suitable for scenarios such as sensor housings, motor end covers, pipe connection flanges, optical instrument mirror seats, etc. It balances small batch prototyping and large-scale mass production, and the factory inspection of size accuracy ensures a stable delivery cycle, providing reliable and precise metal structural component solutions for various equipment.
