Carbon steel 45 # Q235 weldable bearing flange blank with large and small hole diameters

The production of bearing flange blanks is mainly completed through the following core steps, which balance precision and strength requirements in the process:

1. Raw material selection: Low carbon steel, alloy steel and other metal materials are usually selected to ensure sufficient strength and processing performance.

2. Cutting: Processing raw materials into blocks that conform to the size of the blank through cutting, punching, or sawing.

3. Forming processing: Using forging, stamping, or turning processes to process the blank into the basic shape of the flange plate, including the preliminary forming of the flange body and connecting holes.

4. Precision machining: Precision machining such as turning, milling, drilling, etc. is carried out on the formed flange to ensure the flatness of the flange surface, the positional accuracy and dimensional tolerance of the connecting holes.

5. Heat treatment: Quenching, tempering and other heat treatments are carried out according to the requirements to improve the hardness, wear resistance and mechanical properties of the flange.

6. Surface treatment: Surface treatment is carried out through methods such as galvanizing, chrome plating, and painting to enhance the rust and corrosion resistance of flange plates.

7. Quality inspection: Inspect the size, accuracy, hardness, surface quality, etc. of the bearing flange blank to ensure compliance with product standards.

8. Packaging and storage: Packaging qualified bearing flange blanks, classifying them for storage and waiting for assembly or factory delivery.
