Carbide burrs, also referred to 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 also other industries. Choosing the right carbide burr for your project is essential. There are several strategies to choosing a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The contour of the carbide rotary burr needs to be driven by the shape in the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) needs to be used; when processing the interior corner surface, triangular burrs should be selected; when processing the inner right angle surface, a flat burr and square burr may be selected. Once the flat burr can be used to slice the interior right angle surface, it is crucial to create a narrow surface (smooth edge) without teeth close to one of several inner right angle surfaces, in an attempt to avoid damaging the correct angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined in line with the allowance size 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 dimensions and specification of cemented carbide rotary burr needs to be selected based on the sized the workpiece and machining allowance. In the event the machining size is large and the allowance is big, cemented carbide rotary burr using a large size must be selected, or a tungsten carbide rotary burr which has a small size must be selected instead.
