Rotary burs are tools used for metalworking. They are usually made of abrasives that rotate at high speeds and can be used for a variety of metalworking tasks such as cutting, grinding, deburring, and polishing. In the application of large stainless steel pipe fittings, rotary burrs can play the following roles:

1. Cutting: Rotary burrs can be used to cut stainless steel pipe fittings, especially when precise cutting is required.

2. Grinding: During the manufacturing process of stainless steel pipe fittings, rotary burrs can be used to grind the surface of pipe fittings, remove burrs and sharp edges, and make the surface of pipe fittings smooth.

3. Deburring: After welding or cutting, burrs may appear on the edges of stainless steel pipe fittings. Rotary burrs can effectively remove these burrs.

4. Polishing: To improve the appearance quality of stainless steel pipe fittings, rotary burrs can be used for polishing to make the surface of pipe fittings brighter.

5. Drilling: When drilling holes in stainless steel pipe fittings is required, a specific type of rotary burr can be used to complete this task.

6. Finishing: During the manufacturing or installation of pipe fittings, the rotary grinding head can be used to trim the size of the pipe fittings to ensure that they meet the design requirements.

7. Cleaning: The rotary grinding head can also be used to clean the surface of stainless steel pipe fittings to remove dirt and rust.

8. Special shape processing: For pipe fittings that require special shapes or contours, the rotary grinding head can be customized.

When using the rotary grinding head, it is necessary to select the appropriate abrasive type and particle size to adapt to the hardness and processing requirements of the stainless steel. In addition, the operator should take appropriate safety measures, such as wearing protective glasses and gloves, to prevent accidents during high-speed rotation.
