Carbide burrs, also known as carbide rotary burrs are used with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are traditionally used in machinery, automobile, shipbuilding, chemical industry, craft carving, along with other industries. Selecting the most appropriate carbide burr to your project is crucial. There are numerous options for selecting a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form in the carbide rotary burr should be driven by the shape in the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the interior corner surface, triangular burrs needs to be selected; when processing the inner right angle surface, a flat burr and square burr might be selected. In the event the flat burr is employed to slice the interior right angle surface, it’s important to make a narrow surface (smooth edge) without teeth all-around one of several inner right angle surfaces, to be able to avoid damaging the proper angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined based on the allowance height and width of 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 should be chosen as outlined by machining allowance, dimensional accuracy, and surface roughness required by the workpiece.
Sizes of carbide burrs
The size and style and specification of cemented carbide rotary burr should be selected in accordance with the size the workpiece and machining allowance. When the machining sizing is large and also the allowance is big, cemented carbide rotary burr with a large size ought to be selected, or even a tungsten carbide rotary burr using a small size must be selected instead.
