How to Deal With Fastener Burrs?

As a Din Standard Rail Joint Bar Manufacturer, share with you. Fastener burr refers to the extremely fine microscopic metal particles on the surface of the fastener, and these particles become burrs by us.

How does the fastener burr appear when the fastener is formed during cutting, grinding, milling and other similar chip processing. In order to improve the performance and service life of fasteners, it is necessary to remove the burr of the fasteners before using the fasteners. Fasteners are commonly used parts in machinery and equipment, and they are also important parts. Therefore, the surface, sharp angles and edges all need to achieve extremely high metal cleanliness. The main methods for removing burrs are traditional mechanical technology, grinding, polishing and other processes with different degrees of automation.

Chemical processes can also be used to remove the burr of the fastener, so that the quality of the fastener can be better guaranteed. All the fasteners are sequentially immersed in multiple containers, and one of the immersion containers contains a solution. All burrs can be removed through a simple immersion treatment, the surface of the workpiece is smooth and flat, and the edges and corners are smooth, bringing users unprecedented quality. Three issues need attention in fastener maintenance

Although the fasteners are small, they have a great effect. The use of fasteners requires regular maintenance to ensure the safer use of fasteners, and can extend the service life of fasteners and improve the performance of mechanical equipment.

When we are maintaining the Rail Fastening System, there are three major problems:

1. When the fastener is quenched, use silicate cleaning agent to clean up the impurities on it, and then rinse it carefully to avoid impurities remaining on the fastener and affect its normal application.

2.After the fastener is tempered, its color may change. After soaking the fastener in ether for a period of time, an oily substance will be produced. The occurrence of this condition indicates that the fastener Not clean enough. After the analysis, it will be found that when the fasteners are heated, the stacking is not very reasonable, and the fasteners may have some small oxidation phenomena in the quenching oil.

3. If there is a white substance on the fastener, it is likely to be some phosphide. The reason for this phenomenon is that the acid washing machine is not used for cleaning, and the rinsing tank is not carefully checked.

The above problems must be paid attention to, which will directly affect the performance of fasteners, and may also cause the shortening of the service life of fasteners, causing the phenomenon of early damage to fasteners.
