The importance of deburring

1: The impact of burrs on the function of parts and the performance of the whole machine


1. Influence on the wear of parts, the larger the burr on the surface of the part, the greater the energy consumed to overcome the resistance. The presence of burr parts may lead to fit deviation. The rougher the fit part, the greater the pressure per unit area, and the easier the surface is to wear.


2. Influence of anti-corrosion performance. After the surface treatment of the parts, the burrs are easily touched and fall off, which will damage the surface of other accessories. At the same time, a new surface without surface protection will be formed on the burr surface. Under humid conditions, these The surface is more prone to rust and mildew, which affects the corrosion resistance of the whole machine.


 Two: the impact of burrs on subsequent processes and other processes


1. If the machining burr on the reference surface is too large, the machining allowance will be uneven during finishing.


Uneven allowance due to excessive burr When cutting the burr part, the cutting amount of the spindle will suddenly increase or decrease, which will affect the smoothness of cutting, resulting in knife lines or processing stability.


2. If there are burrs on the fine reference surface, the reference surface is easy to overlap, resulting in inaccurate processing dimensions.


3. In the surface treatment process, such as the spraying process, the coated metal will first gather at the tip of the burr part (static electricity is easier to adsorb), resulting in the lack of plastic powder in other parts, resulting in unstable quality.


4. The burr is easy to cause bonding during the heat treatment process, which often destroys the interlayer insulation, resulting in a significant decrease in the AC magnetic properties of the alloy. Therefore, the burr must be removed before heat treatment for some special materials such as soft magnetic nickel alloys.





Three: The importance of deburring


1. Reduce and avoid the presence of burrs that affect the positioning and tightening of mechanical parts and reduce machining accuracy.


2. Reduce the scrap rate of workpieces and reduce the risk of operators.


3. Eliminate the wear and failure of mechanical parts caused by the uncertainty of burrs during use.


4. The adhesion of mechanical parts without burrs will increase when they are painted, so that the coating texture is uniform, the appearance is consistent, smooth and tidy, and the coating is firm and durable.


5. Mechanical parts with burrs are prone to cracks during heat treatment, reducing the fatigue strength of the parts. Deburring of parts under load or parts running at high speed cannot exist.
