Carbide burrs, also known as carbide rotary burrs are employed with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are trusted in machinery, automobile, shipbuilding, chemical industry, craft carving, along with other industries. Selecting the right carbide burr on your project is crucial. There are many strategies to choosing a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form of the carbide rotary burr should be driven by the form in the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the interior corner surface, triangular burrs needs to be selected; when processing the inner right angle surface, an appartment burr and square burr may be selected. In the event the flat burr is used to chop the inner right angle surface, it is necessary to make a narrow surface (smooth edge) without teeth near one of many inner right angle surfaces, in order to avoid damaging the right angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to 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 should be selected. When used, it needs to be chosen based on machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The size and specification of cemented carbide rotary burr needs to be selected in accordance with the height and width of the workpiece and machining allowance. When the machining dimensions are large as well as the allowance is large, cemented carbide rotary burr with a large size must be selected, or perhaps a tungsten carbide rotary burr with a small size needs to be selected instead.
