A Practical Guide To Removing Burrs From The Surface Of Parts With A Disc Brush

Disc brushes are divided into materials: the brush body is PP, PA, POM, PS, ABS, aluminum, bakelite board; the brush filaments are PP, nylon, abrasive filaments, sisal, bristle, etc.

 

There are generally four types of disc brush applications in industry, which boil down to one point: to obtain the required surface finishing effect of the workpiece. Therefore, the main task of the nylon disc brush is the surface processing of the workpiece.

 

Let‘s take a look at the four categories in detail:

 

Satin finishing: Satin finishing is the process of using a soft and fine polishing brush to brush the surface of the part into a matte satin diffuse reflection layer, which can give the surface of the part a non-mirror-like glittering luster.

 

Surface cleaning: The disc brush is mainly used to clean the oxide scale, rust, old paint layer, welding slag and other dirt on the surface of the part. It is also used to brush away the floating dust left after the part is eroded.

 

Silk brushing: Use a CNC deburring abrasive disc brush to brush out a certain regular and fine silk pattern on the surface of the part, such as: wave pattern, fish scale pattern, etc., to achieve the purpose of decoration.

 

Deburring: Remove the burrs on the edges of the surface of the machined part by brushing. This is also the most widely used category of the disc brush in industry.

 

 

 

In the field of industrial production and manufacturing, deburring is a crucial process. Burrs refer to small unwanted protrusions on the edge or surface of parts during the processing of metal, plastic and other materials. These burrs not only affect the appearance quality of the product, but may also affect its performance and service life.

 

The disc brush has a unique structure and brush bristle design, which makes it excellent in deburring work. The brush bristles of the brush disc are soft and elastic, which can fully contact with the surface of the workpiece and effectively remove small burrs.

 

For example, in the processing of metal parts, sharp burrs often appear on the edges after cutting or stamping. At this time, using a disc brush with appropriate hardness and density can quickly and gently remove these burrs without damaging the surface of the part.

 

Another example is plastic products, which may have some tiny burrs after injection molding. The disc brush can easily deal with this situation, remove the burrs cleanly, and make the surface of the plastic product smoother.

 

The disc brush is often used to remove burrs from the surface of parts in industrial production. The use of the disc brush can be summarized into the following steps:

 

 

 

Choosing the Right Disc Brush

 

Brush bristle material: The brush bristles of the CNC deburring brush are made of a variety of materials, such as PP, nylon, abrasive wire, etc. Different materials are suitable for different materials and burr situations. For example, for metal parts, you may need to choose brush bristles with higher hardness; for plastic products, you may need to choose brush bristles that are soft and elastic.

 

Brush bristle hardness and density: The hardness and density of the brush bristles will also affect the deburring effect. Harder brush bristles may be more suitable for removing larger burrs, while softer brush bristles are more suitable for removing small and sensitive burrs. At the same time, the density of the brush bristles will also affect the contact area between the brush bristles and the workpiece surface, thus affecting the deburring efficiency.

 

Adjust Device Parameters

 

Speed: The speed of the disc brush needs to be adjusted according to the material of the workpiece and the size of the burr. Too fast a speed may cause excessive wear on the workpiece surface, while too slow a speed may not effectively remove the burr.

 

Pressure: The pressure of the abrasive disc brushes on the workpiece surface also needs to be properly controlled. Too much pressure may damage the workpiece surface, while too little pressure may not fully contact the workpiece surface, affecting the deburring effect.

 

 

 

Deburring Operation

 

Secure the workpiece: Before beginning deburring, you need to make sure the workpiece is secured to prevent it from moving or rotating during the operation.

 

Start the device: After adjusting the speed and pressure, you can start the device and let the disc brush start rotating.

 

Contact the workpiece: Gently touch the disc brush to the workpiece surface, so that the brush bristles are in full contact with the workpiece surface. During the operation, it is necessary to maintain a stable pressure and speed to ensure consistent deburring effect.

 

Observe the effect: During the operation, you need to constantly observe the deburring effect. If you find that the deburring effect is not good or the workpiece surface is damaged, you need to adjust the equipment parameters or replace the appropriate disc brush in time.

 

 

 

Things to Note

 

Safe operation: When operating a disc brush, you need to wear appropriate protective equipment, such as gloves, goggles, etc., to prevent injuries caused by flying brush bristles or moving workpieces.

 

Regular inspection: It is necessary to regularly check the wear of the disc brush and replace the severely worn brush bristles or the entire CNC deburring brush for aluminum in time to ensure the deburring effect and the normal operation of the equipment.

 

Scope of application: Although the disc brush is widely used to remove burrs from various materials, it also has its scope of application. For some special materials or workpieces with complex shapes, other deburring methods may be required.

 

Through the above steps, the disc brush can be effectively used to remove burrs on the workpiece surface and improve product quality and production efficiency.
