Carbide burrs, often known as carbide rotary burrs are widely-used 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, and other industries. Choosing the right carbide burr on your project is essential. There are several methods for picking a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The contour from the carbide rotary burr ought to be dependant on the design from the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the inner corner surface, triangular burrs must be selected; when processing the interior right angle surface, a set burr and square burr could be selected. If the flat burr is employed to reduce the inner right angle surface, it is necessary to generate a narrow surface (smooth edge) without teeth near among the inner right angle surfaces, so as to avoid damaging the right angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to be determined based on the allowance size the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr would work 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 based on 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 needs to be selected in accordance with the size of the workpiece and machining allowance. If the machining dimension is large along with the allowance is big, cemented carbide rotary burr which has a large size ought to be selected, or perhaps a tungsten carbide rotary burr with a small size must be selected instead.
