Carbide burrs, often 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, and other industries. Selecting the right carbide burr for the project is crucial. There are lots of options for deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The shape in the carbide rotary burr should be determined by the shape from the workpiece. When processing the inner 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 could be selected. If the flat burr is utilized to reduce the inner right angle surface, it is crucial to produce a narrow surface (smooth edge) without teeth near one of several inner right angle surfaces, to be able to avoid damaging the correct angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth should be determined based on 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 should be selected. When used, it should be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr must be selected according to the size the workpiece and machining allowance. Once the machining dimension is large and also the allowance is large, cemented carbide rotary burr having a large size ought to be selected, or possibly a tungsten carbide rotary burr having a small size ought to be selected instead.
