Burrs are metal parts that undergo a series of processing processes during the manufacturing process, such as grinding, drilling, milling, turning, tapping, grooving, etc., and extra protrusions or thorns will inevitably be left after processing.
Affecting the appearance: Burrs will damage the surface finish of the parts and affect the appearance of the product. It will also affect the dimensional accuracy of the parts and make assembly difficult. Sharp burrs may scratch the operator, or cause scratches or damage to other parts during use. It will accelerate the wear of the parts and shorten their use
How to remove burrs after metal processing
Manual deburring
The process of grinding the workpiece and removing burrs using tools such as files, sandpaper, and grinding heads. This is also a commonly used method for removing burrs. It is suitable for small batches and simple-shaped parts, with low cost, but low efficiency and labor intensity. It is difficult to handle parts with complex shapes or burrs in inner holes.
Grinding deburring
Grinding deburring is a method of removing burrs by vibration, sandblasting, drums, etc. The problem with grinding deburring is that sometimes the removal is not very clean, and subsequent manual processing or other methods of deburring may be required. This method is suitable for small products with large batches.
Mechanical deburring
Grinding machines, polishing machines, vibration deburring machines, etc. High efficiency, can handle large batches of parts, suitable for parts with relatively simple shapes. The equipment investment is large, and the technical requirements for operators are high.
Electrochemical deburring
Use an electrochemical reaction to dissolve burrs. Suitable for parts with complex shapes, especially inner hole burrs, with little damage to the surface of parts. The equipment investment is large, requires specific electrolytes, and there are environmental pollution problems.
Thermal deburring
Use high temperature to burn off burrs. It is highly efficient and suitable for large batches of parts. The equipment investment is large, the operating environment requirements are high, and there are safety hazards.
Ultrasonic deburring
Use the cavitation effect generated by ultrasound to peel off the burrs. It is suitable for parts with complex shapes, with little damage to the surface of parts and high efficiency. The equipment investment is relatively large.
When deburring, protective equipment such as gloves and goggles should be worn to protect personal safety.
After deburring, the workbench and equipment should be cleaned in time to keep the working environment clean.
