Carbide burrs, also called carbide rotary burrs are utilized with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are trusted in machinery, automobile, shipbuilding, chemical industry, craft carving, as well as other industries. Choosing the proper carbide burr on your project is crucial. There are several methods for picking a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The contour in the carbide rotary burr needs to be based on the contour in the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the inner corner surface, triangular burrs should be selected; when processing the interior right angle surface, a designated burr and square burr might be selected. When the flat burr is used to slice the interior right angle surface, it is necessary to create a narrow surface (smooth edge) without teeth close to one of many inner right angle surfaces, in order to avoid damaging the best angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth ought to be determined according to the allowance sized the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr is suitable for machining workpieces with large allowance, low dimensional accuracy, large form and position tolerance, large surface roughness value, and soft material; otherwise, fine-tooth carbide burr must be selected. When used, it must be chosen based on machining allowance, dimensional accuracy, and surface roughness essential for workpiece.
Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr must be selected in line with the sized the workpiece and machining allowance. In the event the machining sizing is large along with the allowance is large, cemented carbide rotary burr having a large size needs to be selected, or a tungsten carbide rotary burr using a small size must be selected instead.
