9 methods for removing burrs, burrs, and burrs

April 3, 2024

1. Manual deburring
Manual deburring, as the most primitive and ancient deburring method, is currently used by the vast majority of enterprises. This method uses tools such as sandpaper, grinding head, and file to remove burrs, and the file can also be pneumatic or manual. Artificial deburring does not require high individual technical skills from workers, and is very suitable for products with simple structures and small burrs. However, its disadvantages are high labor costs, low efficiency, and inability to remove some complex cross hole burrs.


2. Deburring of stamping dies
This method involves removing corresponding burrs by using a punching die to match the punching machine. Due to the need to produce corresponding dies, the cost is not too low and is only suitable for products with simple parting surfaces. However, its efficiency and deburring effect are much better than manual labor.


3. Grinding to remove burrs
This deburring method is a combination of various forms such as sandblasting, rolling, and vibration, and is commonly used in many factories. However, the burrs removed by this method are not particularly clean. If they are not completely removed, manual removal will still be required later. At the same time, this method is only suitable for small products and large batches. And this method may cause deformation in thinner areas.


4. Frozen deburring
The method of freezing to remove burrs is to embrittle the burrs at low temperatures, and then spray pellets on the product to achieve the purpose of removing burrs. Using this method to remove burrs requires an investment of over 300,000 yuan in equipment. Secondly, this method is only suitable for workpieces with small burr wall thickness and small product size.


5. Heat explosion deburring
Thermal explosion deburring, also known as thermal deburring, is a method of removing burrs by introducing combustible gas into specific equipment, and then causing the combustible gas to explode under specific conditions and media, using the energy generated by the explosion. Although this method may seem simple and crude, it is costly, costing millions just to purchase equipment. Moreover, it requires high technical skills from workers and is inefficient. But its deburring effect is very good, so this method is usually used in some fields that do not care about cost and value quality, such as aerospace and automotive precision parts.


6. Chemical deburring
By utilizing the principle of electrochemical reactions, the burrs on metal products can be automatically and selectively removed. This method is more commonly used for internal burrs that are difficult to remove. For example, small burrs on workpieces such as valve bodies and pump bodies.


7. Electrolytic deburring
Electrolytic deburring is a method of using electrolysis to remove burrs from metal workpieces. Due to the corrosiveness of the electrolyte used in this method, the surface around the burrs will also be corroded during deburring, causing it to lose its original luster. In severe cases, it can affect the dimensional accuracy of the parts. Therefore, after deburring, the workpiece needs to be cleaned and treated with rust prevention. This deburring method is highly efficient and suitable for concealed and complex shaped burrs in workpieces.


8. High pressure water jet deburring
High pressure water jet deburring, as the name suggests, is a method of achieving the goal of deburring through the instantaneous impact force of water. This method can also clean the workpiece simultaneously. Removing burrs with water may seem simple, but this method is not low-cost and expensive, making it widely used in deburring automotive engines.


9. Ultrasonic deburring
Ultrasonic deburring is a method of removing burrs through the instantaneous high pressure generated by ultrasonic waves. This method is mainly used to remove some very small burrs, such as burrs that can only be observed under a microscope.
