Today, many companies consider whether to add surface treatment when deburring sheet metal parts. Think about it, since you have decided to use a deburring machine to machine the workpiece surface, why not consider finishing the entire surface in one go? precision cnc customized plastic flat washers

Generally speaking, burrs are mostly only produced on the edge, but deburring machines can process the entire surface of the sheet metal part. Due to design, sanding brushes or abrasive belts inevitably leave marks on the surface of the workpiece, especially for stainless steel or aluminum. Metals of these grades are usually not painted or coated so they won’t rust. The processing marks are visible on the surface of the workpiece, which will have a great impact on the overall appearance of the product.

The surface of the workpiece after deburring treatment often presents a certain texture structure. However, not all DIN-compliant workpiece surfaces can be machined with deburring. The reason is simple: deburring machines are mainly used to remove burrs from sheet metal parts. Burrs exist on the edges of sheet metal parts or cuts, not the entire surface.

After the deburring treatment is completed, the next step can be determined according to the needs: some users or customers pay attention to the appearance of the workpiece when it comes out of the machine, which makes it necessary to add a surface treatment processing unit to the deburring machine. Depending on the model, this unit can be retrofitted to the machine at a later date, giving the user the flexibility to respond to changing customer needs. Such retrofit options bring greater convenience and flexibility to customers investing in deburring machines.

If required, the surface treatment unit can be continued after the rounding step of the deburring machine. After the grinding brush and abrasive belt finish the edge and surface treatment of the parts, the burrs or material splashes have been completely removed, which is an important prerequisite for good processing results.

The surface treatment unit itself is equipped with a fine-grained abrasive belt, abrasive flannel or rotating brush. Abrasive belts or abrasive flannels are generally mounted on two rollers and are specially designed to handle the surface of sheet metal parts. This allows the user to obtain a uniform and aesthetically pleasing workpiece. Experts refer to this thread-like finish as “brushed,” even though it’s a non-brushed process. For such parts, it is important to pay attention to the correct orientation of the straight wire when installing it later. The rotary brush is used to achieve non-directional surface finishing for the user, that is, a matte surface. The rotating brush moves in a circle, repeatedly grinding the workpiece from different directions, resulting in a clean and smooth surface.

Before deciding to purchase a surface treatment unit, you can carefully examine the entire process chain. The appearance of the sheet metal part is at risk if processes such as bending, welding, or installing press-fit nuts are required after deburring. Because any further processing may damage the surface, such as leaving scratches. As a result, the beauty of the workpiece after surface treatment is also lost.

If the entire process chain requires processing flexibility, then attention should also be paid to the rational use of other functions of the deburring machine. For example, the surface treatment unit can be switched on and off at any time, so that the machine can perform other processing tasks as required. If the customer wants another finish, the processor can change the abrasive quickly and easily. Finally, it is worth mentioning that it is necessary to have a dust removal system that can be integrated in the machine. It guarantees safe operation of the deburring machine and is “plug and play” without the need for additional connections. Precision cnc customized plastic flat washers
