Carbide burrs, also referred to as 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, and also other industries. Choosing the proper carbide burr on your project is crucial. There are lots of means of selecting a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The shape of the carbide rotary burr needs to be determined by the design 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 must be selected; when processing the inner right angle surface, a flat burr and square burr could be selected. If the flat burr is utilized to slice the interior right angle surface, it’s important to make a narrow surface (smooth edge) without teeth near to one of several inner right angle surfaces, in order to avoid damaging the correct angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined according to 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 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 ought to be selected in accordance with the sized the workpiece and machining allowance. Once the machining dimensions are large and also the allowance is big, cemented carbide rotary burr having a large size must be selected, or perhaps a tungsten carbide rotary burr which has a small size ought to be selected instead.
