Carbide burrs, often known as carbide rotary burrs are employed 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. Selecting the most appropriate carbide burr for your project is essential. There are numerous strategies to deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The design with the carbide rotary burr must be based on the form from the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) ought to be used; when processing the interior corner surface, triangular burrs ought to be selected; when processing the interior right angle surface, an appartment burr and square burr could be selected. When the flat burr is used to cut the inner right angle surface, it is necessary to create a narrow surface (smooth edge) without teeth all-around one of the inner right angle surfaces, in an attempt to avoid damaging the correct angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined based on 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 ought to be selected. When used, it must be chosen based on machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr needs to be selected according to the height and width of the workpiece and machining allowance. If the machining sizing is large as well as the allowance is big, cemented carbide rotary burr with a large size should be selected, or possibly a tungsten carbide rotary burr having a small size must be selected instead.
