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 trusted in machinery, automobile, shipbuilding, chemical industry, craft carving, along with other industries. Choosing the right carbide burr for the project is important. There are several means of choosing a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The design from the carbide rotary burr ought to be driven by the form from 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 inner corner surface, triangular burrs should be selected; when processing the inner right angle surface, a set burr and square burr could be selected. In the event the flat burr can be used to slice the inner right angle surface, it is necessary to make a narrow surface (smooth edge) without teeth near to one of the inner right angle surfaces, so as to avoid damaging the right angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth should be determined in accordance with the allowance height and width of the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr is acceptable 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 needs to be chosen based on machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr must be selected according to the sized the workpiece and machining allowance. In the event the machining dimensions are large as well as the allowance is big, cemented carbide rotary burr with a large size must be selected, or possibly a tungsten carbide rotary burr having a small size ought to be selected instead.
