Carbide burrs, also referred to as carbide rotary burrs are employed 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 right carbide burr for the project is essential. There are lots of methods for picking a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The contour with the carbide rotary burr needs to be dependant on the shape of the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the interior corner surface, triangular burrs must be selected; when processing the interior right angle surface, a flat burr and square burr may be selected. In the event the flat burr is utilized to chop the inner right angle surface, it’s important to create a narrow surface (smooth edge) without teeth near to one of several inner right angle surfaces, so as to avoid damaging the proper angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to be determined in line with the allowance sized 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 ought to be selected. When used, it ought to be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr should be selected in line with the height and width of the workpiece and machining allowance. When the machining sizing is large as well as the allowance is big, cemented carbide rotary burr which has a large size ought to be selected, or a tungsten carbide rotary burr having a small size ought to be selected instead.
