Carbide burrs, often known as carbide rotary burrs are widely-used with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are traditionally used in machinery, automobile, shipbuilding, chemical industry, craft carving, along with other industries. Selecting the most appropriate carbide burr for your project is important. There are several options for deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The design in the carbide rotary burr needs to be determined by the contour of 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 interior right angle surface, an appartment burr and square burr might be selected. If the flat burr can be used to reduce the interior right angle surface, it is crucial to produce a narrow surface (smooth edge) without teeth near 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 needs to be determined based on 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 ought to be selected. When used, it should be chosen based on machining allowance, dimensional accuracy, and surface roughness essential for workpiece.
Sizes of carbide burrs
The size and specification of cemented carbide rotary burr needs to be selected in line with the size of the workpiece and machining allowance. If the machining sizing is large and also the allowance is big, cemented carbide rotary burr which has a large size needs to be selected, or even a tungsten carbide rotary burr with a small size ought to be selected instead.
