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, along with other industries. Choosing the right carbide burr to your project is crucial. There are numerous methods for deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form from the carbide rotary burr needs to be based on the form of the workpiece. When processing the interior 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 inner right angle surface, an appartment burr and square burr might be selected. When the flat burr is employed to reduce the inner right angle surface, it’s important to create a narrow surface (smooth edge) without teeth all-around one of many inner right angle surfaces, so as to avoid damaging the best angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth ought to be determined in line with 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 according to machining allowance, dimensional accuracy, and surface roughness needed by the workpiece.
Sizes of carbide burrs
The size and style and specification of cemented carbide rotary burr should be selected according to the sized the workpiece and machining allowance. If the machining dimensions are large and also the allowance is big, cemented carbide rotary burr having a large size must be selected, or possibly a tungsten carbide rotary burr having a small size must be selected instead.
