How to reduce burrs in Metal Shear cutting - Jiangyin Aupu Machinery Co.,Ltd

Here are some ways to reduce burrs in Metal Shear cutting:
1. Choose the right tool
The sharpness and quality of the tool have an important influence on the generation of burrs. Sharp tools can cut metal more cleanly and reduce the generation of burrs. Therefore, the cutting edge of the tool should be checked regularly, and sharpened or replaced in time when the tool is worn or blunted.
2. Optimize cutting parameters
Parameters such as cutting speed, feed speed and cutting angle need to be reasonably adjusted according to the nature and thickness of the material. Generally speaking, appropriately reducing the cutting speed can give the tool more time to cut off the metal during the cutting process, reducing the tearing and burrs caused by too fast speed. At the same time, reasonably control the feed speed to avoid being too fast or too slow. Too fast feed speed can easily make the cutting surface uneven and produce burrs, while too slow feed speed will affect production efficiency. In addition, adjusting the cutting angle to a suitable value can help to evenly distribute the cutting force and reduce the generation of burrs.
3. Improve the material fixing method
During the cutting process, the stability of the material directly affects the cutting quality. If the material is not firmly fixed, it will shake or move during cutting, which can easily cause the cutting surface to be uneven and produce burrs. Use a special clamp to firmly fix the material on the cutting table to ensure that the material does not move during the cutting process. For some thin materials, a vacuum adsorption device can be used for fixing to provide more stable support and reduce the appearance of burrs.
4. Perform follow-up treatment

After the cutting is completed, some simple follow-up treatment can be performed on the cutting surface to remove burrs. For example, use sandpaper or grinding tools to lightly grind the cutting surface to smooth out the burrs. Chemical treatment methods such as pickling or passivation can also be used to not only remove burrs but also improve the corrosion resistance of the cutting surface.
