CNC Turning for Disc Components
Basic Product Information
The CNC Turning for Disc Components by our company, also known as flanges, are commonly used disc-shaped components in pipeline systems and are typically used in pairs.
The flanges have bolt holes, and the two flanges are tightly connected through bolts. Gaskets are installed between the flanges to achieve sealing and prevent leakage.
The main structural features include the flange sealing surface and bolt holes, making them simple in structure and highly practical.
Product Classification
Our CNC Turning for Disc Components can be classified according to various standards, such as structure, connection method, application field, etc.
Common types include: flat flanges, raised surface flanges, concave flanges, as well as welded flanges, threaded flanges, which can meet different customer needs.
Customers can choose the appropriate flange type based on specific usage conditions.
Processing Accuracy
The CNC Turning for Disc Components by our company require high processing accuracy:
Hole diameter tolerance is generally controlled within ±0.2 mm.
Flatness tolerance is controlled within 0.02 mm.
Verticality tolerance is controlled within 0.015 mm.
Surface roughness is controlled between Ra 0.8 and Ra 1.6 μm.
This accuracy ensures compatibility with pipeline installations and enhances product reliability.
Processing Methods
Our company uses a variety of processes such as turning, milling, planing, grinding, and CNC wire cutting to process the flanges.
Turning: Mainly used to process the flange's inner and outer diameters, end faces, and hole systems.
Milling: Primarily used to process planes, grooves, steps, etc.
Different processing methods are applied based on specific requirements to ensure all parts of the flange meet the accuracy standards.
Product Standards and Production Characteristics
Our flanges are manufactured in accordance with the Chinese national standard GB/T 9118.1–9118.2 or the American standard ASME B16.5.
Under special circumstances, and while adhering to industry standards, adjustments can be made to parameters such as lap welding thickness and pipe length to meet customer customization requirements.
Our flanges are mainly produced in large quantities. During production, we adopt efficient processes such as metal die forging and die forging. The blank processing allowance is small, the precision is high, and the interchangeability is excellent. Reasonable methods are used to ensure accuracy during assembly, and special fixtures, tools, and equipment are utilized to balance production efficiency and product quality.
