Processing Fastener Burrs


Fastener burr is a tiny microscopic metal particle on the surface of the fastener.


How does the fastener burrs come into being?


Fasteners are made by cutting, grinding, milling and other similar chip processing during the formation. In order to improve the performance and service life of the fastener, we need to remove the burrs before using. Fasteners are commonly used in machinery parts, is also one of the important parts, so the surface, and the edge angle needs to achieve high metal cleanliness.


The main ways to remove the burr are:

Traditional mechanical technology, grinding, polishing and other processes with different degrees of automation.


Chemical process can also be used to remove fasteners, so that the quality of fasteners can be better secured, the fasteners are all in turn soaked in a number of containers, one of the immersion container containing CULLYGRAT solution. Through a simple immersion treatment it will be able to remove all the burr, so that provding the workpiece smooth surface, smooth edges and corners, bringing the users an unprecedented high quality. Using CULLYGRAT to carry out chemical removing burr is not only environmental protection but also can save a lot of production and personnel cost.
