Flanged Rotational Machined Parts

This disc-shaped component features dual-side mounting lugs and a central stepped bore. It is commonly used as bearing housings, end caps in mechanical transmission systems, or connection flanges for fluid pipelines. The part achieves secure locking through symmetrically distributed bolt holes on the periphery. The central inner bore,配合 with keyways or positioning steps, ensures coaxiality and assembly precision for rotating components, making it suitable for non-standard equipment assemblies with high positional accuracy requirements.

The manufacturing process strictly controls the coaxiality between the central inner bore and the outer flange surface, as well as the parallelism of the two mounting surfaces, to prevent sealing failures or uneven bolt stress caused by deformation. For such rotational structures, CNC turning is typically employed to ensure inner bore surface finish and dimensional tolerances, supplemented by milling processes to shape the lugs and machine hole positions. For thin-walled areas, clamping solutions are optimized to suppress cutting deformation, ensuring consistency in mass production.

Leveraging high-precision CNC machine tools and coordinate measuring machines (CMM), we provide one-stop services from material selection and rough/fine machining to surface treatment. We support process evaluation based on customer-provided 3D models or 2D engineering drawings. We offer customized production for materials such as stainless steel, carbon steel, and aluminum, verifying critical fit tolerances through rigorous dimensional inspection to meet the comprehensive demands of automated equipment and precision instruments for structural strength and appearance quality.
