Carbide burrs, often known as carbide rotary burrs are utilized with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are popular in machinery, automobile, shipbuilding, chemical industry, craft carving, along with other industries. Selecting the right carbide burr to your project is essential. There are lots of strategies to deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The design with the carbide rotary burr ought to be based on the shape of the workpiece. When processing the interior 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 interior right angle surface, a set burr and square burr could be selected. Once the flat burr is employed to reduce the inner right angle surface, it is vital to make a narrow surface (smooth edge) without teeth close to among the inner right angle surfaces, in order to avoid damaging the right angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined in line with the allowance sized 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 should be chosen according to machining allowance, dimensional accuracy, and surface roughness essential for workpiece.
Sizes of carbide burrs
The size and specification of cemented carbide rotary burr should be selected based on the size the workpiece and machining allowance. In the event the machining sizing is large along with the allowance is large, cemented carbide rotary burr having a large size ought to be selected, or even a tungsten carbide rotary burr using a small size ought to be selected instead.
