Carbide burrs, also called carbide rotary burrs are widely-used 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, and other industries. Selecting the most appropriate carbide burr to your project is important. There are several strategies to selecting 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 shape in the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) needs to be used; when processing the inner corner surface, triangular burrs should be selected; when processing the inner right angle surface, an appartment burr and square burr can be selected. If the flat burr is utilized to cut the interior right angle surface, it is vital to generate a narrow surface (smooth edge) without teeth near one of many inner right angle surfaces, so as to avoid damaging the proper angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to be determined in line with the allowance height and width of the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr is acceptable 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 should be selected. When used, it must be chosen as outlined by machining allowance, dimensional accuracy, and surface roughness essential for workpiece.
Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr needs to be selected based on the size of the workpiece and machining allowance. If the machining dimension is large and the allowance is large, cemented carbide rotary burr with a large size should be selected, or a tungsten carbide rotary burr having a small size should be selected instead.
