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, as well as other industries. Choosing the proper carbide burr to your project is essential. There are lots of methods for selecting a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The design in the carbide rotary burr needs to be dependant on the contour from the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the interior corner surface, triangular burrs should be selected; when processing the inner right angle surface, a designated burr and square burr can be selected. When the flat burr is used to slice the inner right angle surface, it is vital to create a narrow surface (smooth edge) without teeth near to among the inner right angle surfaces, so as to avoid damaging the right angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined based on the allowance height and width 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 must be selected. When used, it should be chosen based on machining allowance, dimensional accuracy, and surface roughness required by the workpiece.
Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr must be selected according to the size the workpiece and machining allowance. If the machining size is large and also the allowance is large, cemented carbide rotary burr using a large size ought to be selected, or perhaps a tungsten carbide rotary burr having a small size needs to be selected instead.
