Carbide burrs, also called carbide rotary burrs are used 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, along with other industries. Selecting the right carbide burr for the project is of great importance. There are lots of methods for picking a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The design of the carbide rotary burr should be based on the form with the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) ought to be used; when processing the interior 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 used to reduce the interior right angle surface, it is vital to create a narrow surface (smooth edge) without teeth all-around one of many inner right angle surfaces, so as to avoid damaging the correct angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth should be determined in accordance with the allowance sized 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 should 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 style and specification of cemented carbide rotary burr should be selected based on the height and width of the workpiece and machining allowance. In the event the machining size is large along with the allowance is large, cemented carbide rotary burr which has a large size needs to be selected, or even a tungsten carbide rotary burr with a small size must be selected instead.
