Carbide burrs, also called carbide rotary burrs are 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, along with other industries. Choosing the proper carbide burr for your project is of great importance. There are numerous means of picking a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The contour in the carbide rotary burr must be determined by the contour from the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) needs to be used; when processing the interior corner surface, triangular burrs ought to be selected; when processing the interior right angle surface, a set burr and square burr may be selected. Once the flat burr is employed to cut the interior right angle surface, it is necessary to generate a narrow surface (smooth edge) without teeth close to one of many inner right angle surfaces, in order to avoid damaging the proper angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth ought to be determined based on the allowance sized 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 ought to be selected. When used, it must be chosen according to machining allowance, dimensional accuracy, and surface roughness essential for workpiece.
Sizes of carbide burrs
The size and style and specification of cemented carbide rotary burr must be selected based on the size of the workpiece and machining allowance. In the event the machining dimensions are large along with the allowance is big, cemented carbide rotary burr having a large size must be selected, or a tungsten carbide rotary burr using a small size ought to be selected instead.
