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, and other industries. Choosing the proper carbide burr for the project is crucial. There are numerous options for deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form with the carbide rotary burr must be driven by the shape in the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) needs to be used; when processing the inner corner surface, triangular burrs ought to be selected; when processing the interior right angle surface, a designated burr and square burr might be selected. When the flat burr is utilized to slice the interior right angle surface, it is vital to make a narrow surface (smooth edge) without teeth close to one of the inner right angle surfaces, so as to avoid damaging the proper angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined in accordance with the allowance size of the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr works 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 ought to be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness required by the workpiece.
Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr must be selected in accordance with the height and width of the workpiece and machining allowance. If the machining sizing is large and the allowance is large, cemented carbide rotary burr with a large size needs to be selected, or a tungsten carbide rotary burr using a small size needs to be selected instead.
