How To Opt For The Perfect Carbide Burrs?
Carbide burrs, also known as carbide rotary burrs are used 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, along with other industries. Selecting the most appropriate carbide burr for your project is of great importance. There are many means of choosing a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form of the carbide rotary burr ought to be determined by the shape with the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the inner corner surface, triangular burrs must be selected; when processing the interior right angle surface, a designated burr and square burr can be selected. Once the flat burr can be used to cut the inner right angle surface, it is vital to produce a narrow surface (smooth edge) without teeth close to 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 works 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 in accordance with 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 needs to be selected based on the height and width of the workpiece and machining allowance. Once the machining size is large as well as the allowance is large, cemented carbide rotary burr with a large size should be selected, or possibly a tungsten carbide rotary burr using a small size should be selected instead.
