How to make high-precision flanges? Detailed explanation of production process

As a connection between pipelines and equipment, flanges have the advantages of easy installation, good sealing, and strong load-bearing capacity. It is connected through bolts for easy disassembly and maintenance, adapts to various pressure, temperature and medium environments, and can ensure the stable operation and safety of the system. Because of its standardized and modular design, it is widely used in petroleum, chemical industry, electric power and other industries. It is an ideal connection solution for high pressure, high temperature and corrosive environments.

In order to meet the company's high-quality requirements for flange performance, many modern flange processing companies choose to use CNC drilling machines for drilling processing. With its efficient processing capabilities and excellent precision control, CNC drilling machines not only greatly improve production efficiency, but also ensure that the hole spacing, hole diameter and depth of each flange strictly meet the design requirements, thereby meeting the requirements of high precision and high stability. Use standards. Yunci Technology’s flange processing uses CNC machining. The process flow is as follows:

• Select materials

Choose the appropriate material. Commonly used materials include carbon steel, stainless steel, alloy steel, etc. Materials are selected according to the actual needs of the product and the working environment to ensure good mechanical properties and good corrosion resistance.

• CNC machining and forming

Processing and shaping. First, the selected materials are cut or die-stamped, and a preliminary blank is made according to the size specifications of the flange. Then, CNC machining, turning, drilling, and trimming of the inner and outer circumferences, apertures, and threads of the flange are performed.

• surface treatment

After cutting, milling, and drilling, the surface of the aluminum alloy flange usually has some burrs or uneven spots. It is necessary to use a deburring tool or sander to ensure that the surface of the flange is smooth.

• Assembly inspection

The processed aluminum alloy flange can be strictly tested for its size, hole diameter, hole spacing, etc. by using measuring tools (such as calipers, micrometers, projectors, etc.) to ensure that it meets the drawing requirements.
