Carbide burrs, also 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 traditionally used in machinery, automobile, shipbuilding, chemical industry, craft carving, and also other industries. Selecting the right carbide burr for the project is crucial. There are lots of options for deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form from the carbide rotary burr must be based on the design in the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) should be used; when processing the inner corner surface, triangular burrs ought to be selected; when processing the interior right angle surface, a set burr and square burr might be selected. Once the flat burr is utilized to cut the interior right angle surface, it is crucial to create a narrow surface (smooth edge) without teeth near to one of the 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 in line with the allowance size of the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr would work 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 needs to be selected. When used, it needs to be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The size and style and specification of cemented carbide rotary burr needs to be selected in line with the height and width of the workpiece and machining allowance. Once the machining dimensions are large and also the allowance is big, cemented carbide rotary burr using a large size should be selected, or even a tungsten carbide rotary burr with a small size ought to be selected instead.
