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 widely used in machinery, automobile, shipbuilding, chemical industry, craft carving, along with other industries. Choosing the right carbide burr on your project is important. There are numerous means of deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form of the carbide rotary burr ought to be based on the form of the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) should be used; when processing the interior corner surface, triangular burrs should be selected; when processing the inner right angle surface, a designated burr and square burr might be selected. In the event the flat burr is employed to slice the interior right angle surface, it is necessary to create a narrow surface (smooth edge) without teeth close to one of the inner right angle surfaces, in order to avoid damaging the best angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must 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 needs to be selected. When used, it must be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness required by the workpiece.
Sizes of carbide burrs
The size and specification of cemented carbide rotary burr must be selected based on the height and width of the workpiece and machining allowance. If the machining dimension is large and the allowance is big, cemented carbide rotary burr having a large size needs to be selected, or a tungsten carbide rotary burr using a small size needs to be selected instead.
