Carbide burrs, also called carbide rotary burrs are widely-used 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, and other industries. Choosing the proper carbide burr to your project is of great importance. There are numerous strategies to choosing a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The design in the carbide rotary burr must be based on the design of the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) ought to be used; when processing the interior corner surface, triangular burrs must be selected; when processing the inner right angle surface, an appartment burr and square burr can be selected. If the flat burr can be used to slice the interior right angle surface, it’s important to create a narrow surface (smooth edge) without teeth near among the inner right angle surfaces, to be able to avoid damaging the right angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth ought to be determined in accordance with 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 must be selected. When used, it must be chosen as outlined by machining allowance, dimensional accuracy, and surface roughness needed by the workpiece.
Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr must be selected based on the height and width of the workpiece and machining allowance. Once the machining sizing is large and also the allowance is big, cemented carbide rotary burr which has a large size must be selected, or possibly a tungsten carbide rotary burr having a small size must be selected instead.
