Carbide burrs, also called carbide rotary burrs are employed with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are popular in machinery, automobile, shipbuilding, chemical industry, craft carving, and also other industries. Choosing the right carbide burr on your project is of great importance. There are numerous methods for selecting a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form of the carbide rotary burr should be based on the shape with the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) should be used; when processing the inner corner surface, triangular burrs should be selected; when processing the inner right angle surface, a designated burr and square burr can be selected. If the flat burr is employed to cut the inner right angle surface, it is vital to make a narrow surface (smooth edge) without teeth all-around one of several inner right angle surfaces, in an attempt to avoid damaging the proper angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to be determined according to the allowance size 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 needs to 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 should be selected based on the height and width of the workpiece and machining allowance. If the machining sizing is large as well as the allowance is large, cemented carbide rotary burr using a large size ought to be selected, or possibly a tungsten carbide rotary burr using a small size ought to be selected instead.
