Carbide burrs, often known as carbide rotary burrs are employed 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, and other industries. Choosing the right carbide burr for the project is essential. There are several methods for picking a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The contour from the carbide rotary burr should be driven by the design in the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the inner corner surface, triangular burrs needs to be selected; when processing the inner right angle surface, an appartment burr and square burr might be selected. In the event the flat burr is utilized to cut the interior right angle surface, it’s important to produce a narrow surface (smooth edge) without teeth near to one of several inner right angle surfaces, in order to avoid damaging the best angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined according to the allowance size 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 ought to be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr should be selected in accordance with the sized the workpiece and machining allowance. Once the machining dimension is large and the allowance is large, cemented carbide rotary burr using a large size should be selected, or possibly a tungsten carbide rotary burr using a small size ought to be selected instead.
