How To Select The Right Carbide Burrs?
Carbide burrs, also referred to 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 other industries. Selecting the right carbide burr for your project is important. There are several methods for choosing a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The contour of the carbide rotary burr needs to be dependant on the shape in 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 should be selected; when processing the inner right angle surface, a set burr and square burr could be selected. Once the flat burr is used to slice the interior right angle surface, it is crucial to generate a narrow surface (smooth edge) without teeth near one of many inner right angle surfaces, in order to avoid damaging the right angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth should be determined based on the allowance size the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr works 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 according to machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The size and specification of cemented carbide rotary burr needs to be selected in accordance with the sized the workpiece and machining allowance. Once the machining dimension is large and the allowance is big, cemented carbide rotary burr having a large size should be selected, or possibly a tungsten carbide rotary burr with a small size should be selected instead.
